Hi,
I have various XML documents in my plug-in which use default XML editor.
Each of these documents have a DTD stored somewhere in my workspace. I want
to validate these XMLs using the DTD without specifying them in the XML
docuement it self but my plug-in should take care of finding this DTD
depending upon editor instance and validating XML document against
respective DTD. Is that possible?
Thanks a lot for your help.

Currently you can only get proper grammar support (validation, content
assist, etc.) for an xml file that specifies a DOCTYPE, xml namespace or
xsi:schemaLocation / xsi:noNamespaceSchemaLocation. Unless you've got one
of those the validator and editor don't know how to find your grammar.
It'd be useful to see a 'sample' of your file to verify that your use case
is a lost cause.
BTW, It's possible that the validator and editor *could* be enhanced to
consider the root element name and use the XML Catalog to look up a
grammar registered for the root element. However, that sounds like a
significant code change and testing effort. Until someone volunteers to
take on such an effort, I'd recommend just modifying your XML files to
provide grammar information (such as a DOCTYPE in the DTD case).
hope that helps!
