NAME Apache::XPointer - mod_perl handler to address XML fragments. SYNOPSIS SetHandler perl-script PerlHandler Apache::XPointer::XPath PerlSetVar XPointerSendRangeAs "application/xml" # 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. SUPPPORTED SCHEMES XPath Consult Apache::XPointer::XPath RDF Data Query Language (RDQL) Consult Apache::XPointer::RDQL MOD_PERL COMPATIBILITY This handler will work with both mod_perl 1.x and mod_perl 2.x.
