XML Notepad – an open-source XML document editor written by Chris Lovett. The editor has good performance when working with large XML documents and provides interactive XML schema validation. The editor also has an HTML viewer to display the results of the XSLT transformation and a built-in XML comparison tool.
XML Notepad is the result of a promise Chris Lovett made to a friend at Microsoft. The original XML Notepad shipped in back in 1998, written by Murray Low in C++. Later on it fell behind in support for XML standards and, because we didn’t have time to fix it, we pulled the downloader. But Murray apparently did such a nice job that MSDN was inundated with requests to put the notepad back up, so they asked for a replacement.
