NAME

       domNode - Manipulates an instance of a DOM node object

SYNOPSIS

        $nodeObject method  arg arg ...
_________________________________________________________________

 DESCRIPTION
       This command manipulates one particular instance of a DOM node object.  method indicates a
       specific method of the node class.  These  methods  should  closely  conform  to  the  W3C
       recommendation  "Document  Object  Model  (Core)  Level  1" (http://www.w3.org/TR/REC-DOM-
       Level-1/level-one-core.html) as well to parts of  the  W3C  draft  "XML  Pointer  Language
       (XPointer)"  (http://www.w3.org/TR/1998/WD-xptr-19980303).  Please note, that the XPointer
       methods are deprecated. Use DOM methods or XPath expressions instead of them.

       The selectNodes method  implements  the  "XML  Path  Language  (XPath)  Version  1.0"  W3C
       recommendation  16  November  1999 (http://www.w3.org/TR/1999/REC-xpath-19991116). Look at
       these documents for a deeper understanding of the functionality.

       The valid methods are:

       nodeType
              Returns the node type of that node object. This can  be:  ELEMENT_NODE,  TEXT_NODE,
              CDATA_SECTION_NODE, COMMENT_NODE or PROCESSING_INSTRUCTION_NODE.

       nodeName
              Returns  the  node  name  of  that  node object. This is the element (tag) name for
              element  nodes  (type  ELEMENT_NODE),   the   processing-instruction   target   for
              processing-instructions,  "#text"  for  text  node, "#comment" for comment nodes or
              "#cdata" for cdata section nodes.

       nodeValue ?newValue?
              Returns the value of that node object. This is the text or  the  data  for  element
              nodes    of    type   TEXT_NODE,   COMMENT_NODE,   PROCESSING_INSTRUCTION_NODE   or
              CDATA_SECTION_NODE).  Otherwise  it  is  empty.  If  the  node  is   a   TEXT_NODE,
              COMMENT_NODE  or  PROCESSING_INSTRUCTION_NODE and the optional argument newValue is
              given, the node is set to that value.

       hasChildNodes
              Returns 1 if the node has children. Otherwise 0 is returned.

       parentNode ?objVar?
              Returns the parent node.

       childNodes
              Returns a list of direct children node objects.

       childNodesLive
              Returns a "live" nodeList object of the child nodes of the node in the sense of the
              DOM recommendation. This nodeList object is "live" in the sense that, for instance,
              changes to the children of the node object that it was created from are immediately
              reflected  in  the  nodes  returned  by  the NodeList accessors; it is not a static
              snapshot of the content of the node. The two accessors known by the nodeList object
              are "item <index>", which returns the indexth item in the collection, and "length",
              which returns the number of nodes in the list.

       firstChild ?objVar?
              Returns the first child as a node object.

       lastChild ?objVar?
              Returns the last child as a node object.

       nextSibling  ?objVar?
              Returns the next sibling relative to the current node as a node object.

       previousSibling ?objVar?
              Returns the next sibling relative to the current node as a node object.

       getElementsByTagName name
              Returns a list of all elements in the subtree matching (glob style) name.

       getElementsByTagNameNS uri localname
              Returns a list of all elements in the subtree matching (glob style)  localname  and
              having the given namespace uri.

       getElementById id
              Returns  the  node  having  an id attribute with value id or the empty string if no
              node has an id attribute with that value.

       hasAttribute attributeName
              Returns 1 if the object node  contains  an  attribute  with  name  attributeName  .
              Otherwise 0 is returned.

       getAttribute attributeName  ?defaultValue?
              Returns the value of the attribute attributeName. If the attribute is not available
              defaultValue is returned.

       setAttribute attributeName newValue  ?attributeName newValue ...?
              Sets the value for one or more  attributes.  Every  attributeName  is  set  to  the
              corresponding  newValue.  If  there  isn't  an  attribute  for  one  or more of the
              attributeName, this will create that attribute.   It  is  not  recommended  to  set
              attributes that look like xml namespace declarations.

       removeAttribute attributeName
              Removes the attribute attributeName.

       hasAttributeNS uri localName
              Returns  1  if  the object node contains an attribute with the local name localName
              within the namespace uri.  Otherwise 0 is returned.

       getAttributeNS uri localName ?defaultValue?
              Returns the value of the  attribute  with  the  local  name  localName  within  the
              namespace  URI  uri.  If  the  node  dosn't have that attribute the defaultValue is
              returned.

       setAttributeNS uri qualifiedName newValue ?uri qualifiedName newValue ...?

              Sets the  value  for  one  or  more  full  qualified  attributes.  Every  attribute
              qualifiedName  with the namespace URI uri will be set to newValue. This will create
              a new attribute, if it wasn't available before. If you want  to  set  an  attribute
              within  a  namespace  you  must specify the attribute name with prefix, even if you
              want to set an already existing attribute to a new value. While searching,  if  the
              attribute already exists, only the given uri and the localname of the qualifiedName
              is used.

                     $node setAttributeNS "http://some.uri.com/wow" prefix:attr1 attrValue

              If the uri is the empty string and the attribute name has no  prefix,  this  method
              has the same effect as the method setAttribute.

                     $node setAttributeNS "" attri "some Value"

              With  the  exceptions  of  the  special  prefixes "xmlns" and "xml" you always must
              provide a non empty uri if your qualifiedName has a prefix. It is  not  recommended
              to  set  xml  namespace  declarations.  The  effects are complicated and not always
              obvious up to resulting a not well-formed serializations after further processing.

       removeAttributeNS uri localName
              Removes the attribute with the local name localName within the namespace uri.

       attributes ?attributeNamePattern?
              Returns information about the  attributes  matching  the  attributeNamePattern.  If
              attributeNamePattern  isn't  given,  information about all attributes are returned.
              The return value is a Tcl list, the elements just the attribute name in case of non
              namespaced  attributes and three element sublists for namespaced attributes. n case
              of an "ordinary"  namespaced  attribute,  the  sublist  elements  are  {<localname>
              <prefix>  <namespace_uri>}.  In the special case of an xml namespace declaration it
              is {<the prefix defined> <localname> ""}.

       attributeNames ?attributeNamePattern?
              Returns a flat list of all attributes names (as found in the XML  source)  matching
              the  attributeNamePattern. If attributeNamePattern isn't given, all attribute names
              are returned as a Tcl list.

       appendChild newChild
              Appends newChild to the end of the child list of the node.

       insertBefore newChild  refChild
              Inserts newChild before the refChild into the list of children of node. If refChild
              is  the  empty  string,  insert newChild at the end of the child nodes list of that
              node.

       replaceChild newChild  oldChild
              Replaces oldChild with newChild in the list of children of that node. The  oldChild
              node will be part of the document fragment list after this operation.

       removeChild child
              Removes  child  from  the list of children of that node.  child will be part of the
              document fragment list after this operation.

       delete Deletes the given node and its complete child tree and frees the complete  internal
              memory. The affected nodes are not accessible through the document fragment list.

       cloneNode ?-deep?
              Clones  this  node and adds the new create node into the document fragment list. If
              the -deep option is specified, all descendant nodes are also cloned.

       ownerDocument ?domObjVar?
              Returns the document object of the document this node belongs to.

       find attrName attrVal ?objVar?
              Finds the node with the attribute name attrName, and attribute value attrVal in the
              subtree starting the current node.

       child number|all type attrName attrValue
              (XPointer) child

       descendant number|all type attrName attrValue
              (XPointer) descendant

       ancestor number|all type attrName attrValue
              (XPointer) ancestor

       fsibling number|all type attrName attrValue
              (XPointer) fsibling

       psibling number|all type attrName attrValue
              (XPointer) psibling

       root  objVar
              (XPointer) root

       text   Returns  all  text  node children of that current node combined, i.e. appended into
              one string.

       target For a processing instruction node the target part is returned.  Otherwise an  error
              is generated.

       data   For  a  processing  instruction  node  the  data part is returned. For a text node,
              comment node or cdata section node the value is returned.  Otherwise  an  error  is
              generated.

       prefix Returns the namespace prefix.

       namespaceURI
              Returns the namespace URI.

       localName
              Returns the localName from the tag name of the given node.

       selectNodes ?-namespaces prefixUriList? ?-cache <boolean>? xpathQuery ?typeVar?

              Returns  the result of applying the XPath query xpathQuery to the subtree. This can
              be a string/value, a list of strings, a list of nodes or a list of attribute name /
              value  pairs. If typeVar is given the result type name is stored into that variable
              (empty, bool, number, string, nodes, attrnodes or mixed).

              The argument xpathQuery has to be a valid XPath expression.  However  there  are  a
              few  exceptions  to  that  rule.  Tcl variable references (in the usual tcl syntax:
              $varname) may appear in the XPath statement at  any  position  where  it  is  legal
              according  to  the rules of the XPath syntax to put an XPath variable. Ignoring the
              syntax rules of XPath the Tcl variable name may be any legal Tcl  var  name:  local
              variables, global variables, array entries and so on. The value will always be seen
              as string literal by the xpath engine. Cast the value explicitly with the according
              xpath functions (number(), boolean()) to another data type, if needed.

              Similar  to  the  way  described  above to inject literals in a secure way into the
              XPath expression using tcl variable references there is a syntax to inject  element
              names  from tcl variables. At every place where the XPath syntax allows a node test
              there could be a tcl variable reference (in any form), just the leading $  replaced
              with  %.  This allows one to select nodes with 'strange' (invalid, according to the
              appropriate XML production rule) node names which may be needed in case of  working
              with JSON data.

              The  option  -namespaces  expects  a  tcl  list  with  prefix  / namespace pairs as
              argument. If this option is not given, then any namespace prefix within  the  xpath
              expression  will be first resolved against the list of prefix / namespace pairs set
              with the selectNodesNamespaces method for the document, the  node  belongs  to.  If
              this  fails,  then  the  namespace definitions in scope of the context node will be
              used to resolve the prefix. If this option is given, any  namespace  prefix  within
              the  xpath  expression will be first resolved against that given list (and ignoring
              the document global prefix / namespace list). If the list binds the same prefix  to
              different  namespaces,  then  the  first binding will win.  If this fails, then the
              namespace definitions in scope of the context node will  be  used  to  resolve  the
              prefix, as usual.

              If  the -cache option is used with a true value, then the xpathQuery will be looked
              up in a document specific cache. If the  query  is  found,  then  the  stored  pre-
              compiled  query  will  be  used.  If the query isn't found, it will be compiled and
              stored in the cache, for use in further calls.  Please  note  that  the  xpathQuery
              given  as  string  is  used  as  key  for  the  cache. This means, that equal XPath
              expressions, which differ only in  white  space  are  treated  as  different  cache
              entries.  Special  care  is  needed,  if  the  XPath  expression includes namespace
              prefixes or references to tcl variables.  Both namespace prefixes and tcl  variable
              references  will be resolved according to the XML prefix namespace mappings and tcl
              variable values at expression compilation time. If the  same  XPath  expression  is
              used  later  on  in a context with other XML prefix namespace mappings or values of
              the used tcl variables, make sure to first remove the compiled expression from  the
              cache  with  the  help  of  the  deleteXPathCache method, to force a recompilation.
              Without using the -cache option such consideration is never needed.

              Examples:

                     set paragraphNodes [$node selectNodes {chapter[3]//para[@type='warning' or @type='error'} ]
                     foreach paragraph $paragraphNodes {
                         lappend  values [$paragraph selectNodes attribute::type]
                     }

                     set doc [dom parse {<doc xmlns="http://www.defaultnamespace.org"><child/></doc>}]
                     set root [$doc documentElement]
                     set childNodes [$root selectNodes -namespaces {default http://www.defaultnamespace.org} default:child]

       getLine
              Returns the line number of that node in the originally parsed XML.

       getColumn
              Returns the column number of that node in the originally parsed XML.

       asList Returns the DOM substree starting form the current node as a nested Tcl list.

       asXML ?-indent none/tabs/1..8? ?-channel channelId? ?-escapeNonASCII? ?-doctypeDeclaration
       <boolean>?  -xmlDeclaration <boolean>? -encString <string> ?-escapeAllQuot? ?-indentAttrs?
       ?-nogtescape? ?-noEmptyElementTag?

              Returns the DOM substree starting from the current node as the  root  node  of  the
              result  as  an  (optional  indented) XML string or sends the output directly to the
              given channelId.

              See the documentation of the of the

              domDoc  command method asXML for a detailed description of the arguments.

       asHTML  ?-channel  channelId?   ?-escapeNonASCII?   ?-htmlEntities?   ?-doctypeDeclaration
       <boolean>? ?-breakLines? ?-onlyContents?

              Returns  the  DOM  substree  starting from the current node as the root node of the
              result serialized according to HTML rules (HTML elements are recognized  regardless
              of  case,  without  end  tags for empty HTML elements etc.), as string or sends the
              output directly to the given channelId.

              See the documentation of the the

              domDoc  method asHTML for a detailed description of the arguments.

       asText For ELEMENT_NODEs, the asText method outputs the string-value of  every  text  node
              descendant  of  node  in  document order without any escaping. For every other node
              type, this method outputs the XPath string value of that node.

       appendFromList list
              Parses list , creates an according DOM subtree and  appends  this  subtree  to  the
              current node.

       appendFromScript tclScript
              Appends  the nodes created in the tclScript by Tcl functions, which have been built
              using dom createNodeCmd, to the given node.

       insertBeforeFromScript tclScript refChild
              Inserts the nodes created in the tclScript by Tcl functions, which have been  built
              using  dom createNodeCmd, before the refChild into the list of children of node. If
              refChild is the empty string, the new nodes will be appended.

       appendXML XMLstring
              Parses XMLstring, creates an according DOM subtree and appends this subtree to  the
              current node.

       simpleTranslate outputVar specifications
              Translates  the subtree starting at the object node according to the specifications
              in  specifications  and  outputs  the  result  in  the  variable  outputVar  .  The
              translation is very similar to Cost Simple mode.

       toXPath ?-legacy?
              Returns  an  XPath,  which  exactly  addresses the given node in its document. This
              XPath is only valid as there are no changes to DOM tree made later  one.  With  the
              -legacy  option,  other  XPath  expressions are returned, which doesn't work in all
              cases.

       getBaseURI
              Returns the baseURI of the node. This method is deprecated in favor of the  baseURI
              method.

       baseURI ?URI?
              Returns  the present baseURI of the node. If the optional argument URI is given, it
              sets the base URI of the node and of all of its child nodes out of the same  entity
              as node to the given URI.

       disableOutputEscaping ?boolean?
              This  method  works  only  for  text  nodes; for every other node it returns error.
              Without the optional argument it returns, if disabling output escaping is  on.  The
              return  value 0 means, the characters of the text node will be escaped, to generate
              valid XML, if serialized. This is the default for every parsed or created text node
              (with  the exception of that text nodes in a result tree of an XSLT transformation,
              for which disabling output escaping was requested explicitly  in  the  stylesheet).
              The  return  value 1 means, that output escaping is disabled for this text node. If
              such a text node is serialized (with asXML or asHTML),  it  is  literally  written,
              without  escaping  of  the  special  XML  characters. If the optional boolean value
              boolean is given, the flag is set accordingly. You should not set this  flag  to  1
              until you really know what you do.

       precedes refnode
              Compares the relative order of the node and refnode. Both nodes must be part of the
              same documents and not out of the fragment list of the document.  Returns  true  if
              node  is  in  document  order (in the sense of the XPath 1.0 recommendation) before
              refnode, and false otherwise.

       normalize ?-forXPath?
              Puts all Text nodes in the full depth of the sub-tree underneath this Node  into  a
              "normal"   form   where   only  structure  (e.g.,  elements,  comments,  processing
              instructions and CDATA sections) separates Text  nodes,  i.e.,  there  are  neither
              adjacent  Text  nodes  nor  empty Text nodes. If the option -forXPath is given, all
              CDATA sections in the nodes are converted to text nodes, as a first step before the
              normalization.

       xslt   ?-parameters   parameterList?  ?-ignoreUndeclaredParameters?  ?-maxApplyDepth  int?
       ?-xsltmessagecmd script? stylesheet ?outputVar?
              Applies an XSLT transformation on the document using the XSLT stylesheet (given  as
              domDoc).  Returns  a  document  object  containing  the  result  document  of  that
              transformation and stores it in the optional outputVar.

              The optional -parameters option sets top level <xsl:param> to  string  values.  The
              parameterList has to be a tcl list consisting of parameter name and value pairs.

              If  the  option  -ignoreUndeclaredParameters  is given, then parameter names in the
              parameterList given to the -parameters options that are not declared  as  top-level
              parameters in the stylesheet are silently ignored. Without this option, an error is
              raised if the user tries to set a top-level parameter which is not declared in  the
              stylesheet.

              The  option  -maxApplyDepth expects a positive integer as argument. By default, the
              xslt engine allows xslt templates to nest up to 3000 levels (and  raises  error  if
              they nest deeper). This limit can be set by the -maxApplyDepth option.

              The  -xsltmessagecmd  option  sets  a  callback  for  xslt:message  elements in the
              stylesheet. The actual command consists of the script, given  as  argument  to  the
              option,  appended  with the XML Fragment from instantiating the xsl:message element
              content as string (as if the XPath string() function would have been applied to the
              XML  Fragment) and a flag, which indicates whether the xsl:message has an attribute
              "terminate" with the value "yes". If the called script returns anything  else  then
              TCL_OK then the xslt transformation will be aborted, returning error. If the called
              script returns -code break the error message is empty, otherwise the result code is
              reported.  In  case of terminated transformation the outputVar, if given, is set to
              the empty string.

       @attrName
              Returns the value of the attribute attrName.  Short cut for getAttribute.

       jsonType ?OBJECT|ARRAY|NONE)|(STRING|NUMBER|TRUE|FALSE|NULL|NONE)?
              Only element and text nodes may have a JSON type  and  only  this  types  of  nodes
              support  the jsonType method; the other node types return error if called with this
              method.  Returns the jsonType of the node. If the optional argument is  given,  the
              JSON  type  of the node is set to the given type and returned. Valid type arguments
              for element nodes are OBJECT, ARRAY and NONE. Valid type arguments for  text  nodes
              are STRING, NUMBER, TRUE, FALSE, NULL and NONE.

       Otherwise, if an unknown method name is given, the command with the same name as the given
       method within the namespace ::dom::domNode is tried to  be  executed.  This  allows  quick
       method additions on Tcl level.
