But in cpan, it says you can parse the object of xml parser too to the xpath. Here is the CPAN XML::XPATH content Parameters you can use are: filename, parser, xml, ioref and context. The 4 parameters filename, xml, ioref and context are mutually exclusive - you should only specify one (if you specify anything other than context, the context node is the root of your document). The parser option allows you to pass in an already prepared XML::Parser object, to save you having to create more than one in your application (if, for example, you're doing more than just XPath). Since I wanted to validate the xml against DTD and then give it to XPath, I used the option of creating parser object, validate against DTD and pass it to the XPath. Thanks, Sunil.

I think you misunderstand what that means. You can pass it a pre-created XML::Parser for it to use but you still have to pass one of filename, xml, ioref or context. And you still have to use named parameters. e,g. $xpath = XML::XPath(parser => $xml_parser, filename => $file ); /J _______________________________________________ Perl-XML mailing list Perl-XMLlistserv.ActiveState.com To unsubscribe: http:/ /listserv.ActiveState.com/mailman/mysubs

Thanks. I misunderstood. It works now. Any idea how to set the relative path of DTD document that is specified in the xml. How should I ask parser to look for DTD document in a particular place.
