NAME

       XML::LibXML::Attr - XML::LibXML Attribute Class

SYNOPSIS

         use XML::LibXML;
         # Only methods specific to Attribute nodes are listed here,
         # see XML::LibXML::Node manpage for other methods

         $attr = XML::LibXML::Attr->new($name [,$value]);
         $string = $attr->getValue();
         $string = $attr->value;
         $attr->setValue( $string );
         $node = $attr->getOwnerElement();
         $attr->setNamespace($nsURI, $prefix);
         $bool = $attr->isId;
         $string = $attr->serializeContent;

DESCRIPTION

       This is the interface to handle Attributes like ordinary nodes. The naming of the class
       relies on the W3C DOM documentation.

METHODS

       The class inherits from XML::LibXML::Node. The documentation for Inherited methods is not
       listed here.

       Many functions listed here are extensively documented in the DOM Level 3 specification
       (<http://www.w3.org/TR/DOM-Level-3-Core/>). Please refer to the specification for
       extensive documentation.

       new
             $attr = XML::LibXML::Attr->new($name [,$value]);

           Class constructor. If you need to work with ISO encoded strings, you should always use
           the "createAttribute" of XML::LibXML::Document.

       getValue
             $string = $attr->getValue();

           Returns the value stored for the attribute. If undef is returned, the attribute has no
           value, which is different of being "not specified".

       value
             $string = $attr->value;

           Alias for getValue()

       setValue
             $attr->setValue( $string );

           This is needed to set a new attribute value. If ISO encoded strings are passed as
           parameter, the node has to be bound to a document, otherwise the encoding might be
           done incorrectly.

       getOwnerElement
             $node = $attr->getOwnerElement();

           returns the node the attribute belongs to. If the attribute is not bound to a node,
           undef will be returned. Overwriting the underlying implementation, the parentNode
           function will return undef, instead of the owner element.

       setNamespace
             $attr->setNamespace($nsURI, $prefix);

           This function tries to bound the attribute to a given namespace. If $nsURI is
           undefined or empty, the function discards any previous association of the attribute
           with a namespace. If the namespace was not previously declared in the context of the
           attribute, this function will fail. In this case you may wish to call setNamespace()
           on the ownerElement. If the namespace URI is non-empty and declared in the context of
           the attribute, but only with a different (non-empty) prefix, then the attribute is
           still bound to the namespace but gets a different prefix than $prefix. The function
           also fails if the prefix is empty but the namespace URI is not (because unprefixed
           attributes should by definition belong to no namespace).  This function returns 1 on
           success, 0 otherwise.

       isId
             $bool = $attr->isId;

           Determine whether an attribute is of type ID. For documents with a DTD, this
           information is only available if DTD loading/validation has been requested. For HTML
           documents parsed with the HTML parser ID detection is done automatically.  In XML
           documents, all "xml:id" attributes are considered to be of type ID.

       serializeContent($docencoding)
             $string = $attr->serializeContent;

           This function is not part of DOM API. It returns attribute content in the form in
           which it serializes into XML, that is with all meta-characters properly quoted and
           with raw entity references (except for entities expanded during parse time). Setting
           the optional $docencoding flag to 1 enforces document encoding for the output string
           (which is then passed to Perl as a byte string).  Otherwise the string is passed to
           Perl as (UTF-8 encoded) characters.
