Joe, Thanks very much for your time in clearing my doubts :-) >Depends on what you mean by "traverse". Might help if you provided a >concrete example. By "traverse" I meant complete access to the src. XML tree. in all possible ways. for eg. say getting all the nodes that are children of say "foo" element etc. I guess all that is possible through the pattern syntax of XSL, and if some of the "traversals"(as I read it) are not then the pattern syntax needs to be made richer (as you stated) rather than DOM interfaces being introduced. >If you mean you want to do something more complicated than XSL's query >language and templates will support, you either don't use XSL, or you use >the escape mechanisms that may (or may not) be designed into XSL. Yes. Now I understand , why there is no place for DOM into XSL. DOM is an API used by a prog. lang/application, XSL is neither , simply because it was put togther to be a query , tranformation language. So anything outside the scope of patterns / templates , will need an escape mech. (in case of DOM a programming language , as Paul pointed out). > Early versions of XSL did have some support for Ecmascript, which was given >DOM-like read-only access into the model... The current spec doesn't have >that feature, It was the "DOM-like read-only access" in the earlier versions that made me think of DOM with XSL. >but I get the impression that it hasn't yet been ruled out for future versions. I feel it would be proper to have "DOM-like read-only access" methods as they would leverage the XSL pattern syntax by giving them a DOM like feel.
