Hi Craig,
Thanks for the info. I followed the example you mentioned but it still does not work. We are trying to validate against a DTD that is at a specific path in the local file system. It seems that the 'file:' URL does not work because we need to specify the 'd:' windows drive. The XML, DTD and error message are included below. Any idea how to make it to work ? Thanks, Tal ------------- templates.xml -------------- <?xml version="1.0" ?> <!DOCTYPE Templates PUBLIC "-//Netscape Communications//DTD RSS 0.91//EN" "http://my.netscape.com/publish/formats/rss-0.91.dtd";> <!-- Experimental XML based config file.
