XML for mIRC Beta

By Mpdreamz on Nov 29, 2008

This is the first beta of XML support in mIRC. There's two example aliases that show how to use it. Once im confident it's bug free and I've added all the functionality i still want too implement ill write up a decent API documentation. The example snippets are very self explanatory.

                "XML Extensions For mIRC 1.0" (XMLEX for short) provides a complete set of aliases to
                create,fetch,load,manipulate,navigate & transform XML documents
