NAME ^

Apache::XPointer - mod_perl handler to address XML fragments.

SYNOPSIS ^

 <Directory /foo/bar>

  <FilesMatch "\.xml$">
   SetHandler   perl-script
   PerlHandler  Apache::XPointer::XPath

   PerlSetVar   XPointerSendRangeAs    "application/xml"
  </FilesMatch>

 </Directory>

 #

 my $ua  = LWP::UserAgent->new();
 my $req = HTTP::Request->new(GET => "http://example.com/foo/bar/baz.xml");

 $req->header("Range"  => qq(xmlns("x=http://example.com#")xpointer(*//x:thingy)));
 $req->header("Accept" => qq(application/xml));

 my $res = $ua->request($req);

DESCRIPTION ^

Apache::XPointer is a mod_perl handler to address XML fragments using the HTTP 1.1 Range and Accept headers and the XPath scheme, as described in the paper : A Semantic Web Resource Protocol: XPointer and HTTP.

Additionally, the handler may also be configured to recognize a conventional CGI parameter as a valid range identifier.

If no 'range' property is found, then the original document is sent unaltered.

If an Accept header is specified with no corresponding match, then the server will return (406) HTTP_NOT_ACCEPTABLE. Successful queries will return (206) HTTP_PARTIAL_CONTENT.

IMPORTANT ^

This package is a base class and not expected to be invoked directly. Please use one of the scheme-specific handlers instead.
