I'm teaching XSLT and using for it the XMLCopy Editor. Because it's for educational use, I need open source software and that one fits perfect for my purpose. The problem is that XMLCopy Editor doesn't support XPath 2.0, and all the online free processors can't handle with files larger than 2Mb, in the other hand, I prefer not to use the command line, because my students are not used to use it, besides each one use a different operating system. Do you know any alternative software with those requirements? Thanks in advance.
