The leading XML/XSLT Editor and Integrated Development Environment. Need an XSLT editor which has element and attribute Intellisense? How about automatic tag completion? The XPath query analyzer tests XPath queries to see the resulting node sets and the debugger has full stepping capability and breakpoints on both XSLT and input XML. You can also view the template call stack during transformations. Don't use MSXML? Xselerator also uses alternative command line transformation engines (e.g. Instant Saxon, XT, etc.).
