Binary package “tdom” in ubuntu bionic

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

 tDOM takes advantage of Expat, the XML parser from James Clark,
 including namespace 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 basic feature
 set. tDOM interfaces with the gumbo HTML5 parser and provides a robust
 JSON parser/ serializer for JSON-to-JSON roundtripping. Documentation is
 provided in TMML, HTML and nroff formats.
