A fast XML/DOM/XPath/XSLT extension for Tcl written in C

 tDOM takes advantage of Expat, the XML parser from James Clark,
 including namesspace and DTD support. It includes a modified version
 of Tclexpat, the Tcl interface to Expat, and comes with a (partial)
 DOM-I and DOM-II implementation in C for maximum performance and minimum
 memory need. A very complete, compliant and fast XPath implementation
 is provided. A fast XSLT implementation in C completes the feature
 set. Documentation is provided in TMML, HTML and nroff formats.
