I am looking for a Xsl transformation free online editor. I have found w3schools TryIt Editor, but I need some more extended one. I need a tool with custom output formatting and more.

  • What exactly do you mean by "custom output formatting"? Indentation? Syntax highlighting? Markup rather than result?

  • @Eric indentation, syntax highlighting at least

There is an open source in browser editor called CodeMirror. It doesn't hace an xsl parser, but you can add one. It does have an xml/html and an xquery parser

  • In other words, "roll-your-own", nothing pre-existing out there.... Commented Oct 12, 2010 at 14:29
