       rxp - XML parser program


       rxp [ -abemnNRsStvVx4 ] [ -o b|p|0|1|2|3|i|d ] [ U 0|1|2 ] [ -c encoding ] [ url ]


       rxp  reads  and parses XML from the url (or standard input if none is provided) and writes
       it  to  standard  output,  optionally  expanding  entities,  defaulting  attributes,   and
       translating to a different output encoding.

       rxp  accepts  XML  1.0  and  1.1,  and  the  corresponding versions of XML namespaces.  It
       implements the Oasis XML catalog specification.

       Common option combinations are -Nxs to check a document for well-formedness and  namespace
       well-formedness, and -VNxs to also check for DTD-validity.


       -a     Insert declared default values for omitted attributes.

       -v     Be verbose.

       -V     Validate  the document.  Repeating this option will make the program treat validity
              errors  as  well-formedness  errors,  and  exit  after  the  first  validity  error
              (otherwise a warning will be printed for each one).

       -d     Read  the  whole  DTD  (internal  and  external parts) regardless of any standalone
              declaration.  Otherwise a declaration "standalone='yes'" will prevent the  external
              part from being read (unless validation is selected).

       -N     Enable  XML  namespace support.  The document will be checked for correct namespace
              syntax, and if -b is specified  qualified  element  and  attribute  names  will  be
              displayed with their URIs.

       -R     The  value  of  this  flag is a time limit in seconds, after which the program will
              abort.  This is  to  protect  against  denial-of-service  attacks  using  malicious

       -S     Keep  track  of  xml:space  attributes.   This  will  only affect output when -b is

       -e     Obsolete, do not use.

       -E     Do not expand entity references (opposite of old -e flag)

       -s     Be silent (that is, suppress output).  Useful for benchmarking or if you just  want
              to see the error messages.

       -b     Print output as "bits".

       -n     Treat the input as normalised SGML rather than XML.  Not intended for general use.

       -o     If  this  flag is p, output is in the default (plain) format. If it is b, output is
              printed as "bits"  (equivalent  to  -b).     If  it  is  0,  output  is  suppressed
              (equivalent  to  -s).   If  it  is  1,  2 or 3, output is in first, second or third
              canonical form.  If it is i, output is a dump of the document's infoset.  If it  is
              d,  output  is in a form suitable for use with "diff"; in particular attributes are
              sorted into alphabetical order.

       -m     Merge PCData across entity references.  This will only affect the output when -b is

       -t     Read  in  the  input as a tree, rather than bits.  Should make no difference to the

       -u base_uri
              Use the specified base URI when resolving system identifiers.

       -U     This flag controls Unicode normalization checking and is only relevant when parsing
              XML  1.1  documents.  If it is 0, no checking is done.  If it is 1, rxp checks that
              the document is fully normalized as defined by the W3C character model.  If  it  is
              2,  the  document  is  checked  and  any  unknown  characters  (which  may  be ones
              corresponding to a newer version of Unicode than rxp knows about) will  also  cause
              an error.

       -x     Strict  XML  mode.   This  suppresses  some  warnings (eg entity redefinitions) but
              treats all XML well-formedness errors as fatal.  This flag implies the -a flag, and
              sets  the output encoding to UTF-8 unless the -c flag is given.  It sets the output
              format to first canonical form unless the -o, -b or -s flag is given.

       -c encoding
              Produce output in  the  specified  character  encoding.   Known  encodings  include
              ISO-8859-1,  UTF-8, ISO-10646-UCS and UTF-16.  16-bit encoding names my be suffixed
              with -B or -L to specify big- or little-endian byte order (the default is the  host
              byte order).  If no -c or -x option is given, output is in the same encoding as the
              input document.

       -D name sysid
              Force use of the document type specified by  sysid.   The  root  element  name  for
              validation  is name.  Any DTD in the document is ignored.  This flag does not imply
              validation; use -V if required.

       -i     Do xml:id processing.  Attributes named xml:id are recognised as IDs  even  if  not

       -I     The same as -i, but in addition xml:id attributes are checked for uniqueness.

       -z     Use a shorter format for error messages.  Particularly useful when using the parser
              in Emacs compilation mode, so that Emacs can find the error location.

       -4     Use pre-fifth-edition rules for XML 1.0.  XML 1.0 fifth edition extends the set  of
              allowed  name  characters to match XML 1.1, and allows unrecognised version numbers
              of the form 1.x to be treated as 1.0.  the -4 flag disables these changes.


       If the -V flag is given, and the document is well-formed but not valid, 2 is returned.  If
       the  document is not well-formed, or a system error occurs, 1 is returned.  Otherwise 0 is
       returned.  Since the parser can expand external entities  even  when  not  validating,  it
       treats certain errors which are technically validity errors as well-formedness errors.  If
       -x is not specified, some well-formedness errors produce only warnings and do  not  affect
       the exit status.


       If  the  environment variable XML_CATALOG_FILES is set, XML catalog processing is enabled.
       A catalog can be used to map system and public identifiers to local files.  In particular,
       this  allows  copies of common DTDs to be kept locally, so that rxp does not have to fetch
       them over the internet.  XML_CATALOG_FILES should be set  to  a  space-separated  list  of
       catalog  files.  The variable XML_CATALOG_PREFER may be set to public or system to set the
       initial mode for catalog processing; the default is system.

       If the variable RXPURL is set, it is used as the URL of the document to parse.   This  may
       be useful in CGI scripts and the like to avoid shell parsing of a user-supplied argument.

       The  variable  http_proxy can be used to specify a proxy for HTTP connections.  The syntax
       is hostname[:port].
