Some of my projects:
TeXstudio: a LaTeX editor with grammar/syntax checking, pdf viewer and other things.
Pascal Internet Tools: A dependency-free Pascal implementation of a HTML parser, CSS 3 Selectors, a standard conformant XPath/XQuery 3.1 interpreter with a compatibility mode for XPath 2 and XQuery 1 as well as extensions for JSONiq and pattern matching.
Xidel: Command line tool to extract data from X/HTML files, entire webpages, and JSON documents. (basically the same as the Internet Tools, but not tied to Pascal)
XPath/XQuery online tester: CGI-Version of Xidel
