XMLMate plugin for TextMate

The XMLMate Plug-In adds an XML parsing palette to the popular TextMate text editor for Mac OS X. While editing an XML (or XHTML) document in TextMate, you can open the XMLMate palette to conveniently check your document for well-formedness or validity against a DTD, W3C XML Schema, RELAX NG schema, or Schematron schema.
