LT XML is an integrated set of XML tools and a developers' tool kit,
including a C-based API.

The LT XML tool kit includes stand-alone tools for a wide range of
processing of well-formed XML documents, including searching and
extracting, down-translation (for example, report generation,
formatting), tokenizing and sorting.

For special purposes beyond what the pre-constructed tools can achieve,
extending their functionality and/or creating new tools is easy using
the LT XML API. Minimal applications require less than one-half page of
C code to express.

LT XML provides two views of an XML file; one as a flat stream of
markup elements and text; a second as a sequence of tree-structured XML
elements. The two views can be mixed, allowing great flexibility in the
manipulation of XML documents. It also includes a powerful, yet simple,
querying language, which allows the user to quickly and easily select
those parts of an XML document which are of interest.
