Application made with Mono 2.0, compatible with .NetFramework 2.0. It allows to load and modify xml, xsd and xsl docs and perform theirs validation, also using an embedded browser. Also, it allows to apply xsl to xml and to validate xml with xsd.
Another Diff is a utility like anothers diff utilities but that's works how I want and its run in mono also, so can be used in Linux and Windows.
No is necessary install, or install any third part library to run (Except mono or .netframework).
