I do a lot of xml transformation, on pretty large files 5-150MB, and I have for the most part used Websphere transformation extender for some years now, because that is what we have at work. This is okay, but a bit heavy for the task, and I find it hard to find good examples on usage on the web. Also we are heavy into .net, so not sure why we use it.I've also done some transformation in C# using XLinq, and that is all fine, but I want to avoid calling a exe file, cause its pain to rebuild it and redistributed it.I'm looking into xslt now, and I like it, but where is it heading? No brower is supporting xsl 2.0 right off the bat. Also no native support for it in .net? 2.0 has been out over 5 years now...So my questions are: Should I skip trying to learn 2.0 in great detail, or will it come sooner or later?What are people using to process heavy documents?
