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.
