Luckily, libxslt is available. You just read and parse the original XML file, then apply your XSL style sheet to it. > 3.

There have been lots of threads on the subject of document merging on the Mulberry Tech XSL list. Check out: http://www.mulberrytech.com/xsl/xsl-list/ You can get high quality help here. My personal experience with libxslt used in conjunction with libxml2 has been very good. It works very well. > 4. I have a template XML file and a config XML file.

Or maybe just into the proper places in a text file. Or maybe as attributes on some element.
