Bare XML is a "bare" XML parser with all primary parsing done via a simple state engine with about 20 or so different states. A tree structure is created during parsing, with all node names and values linked via pointers directly into the original text buffer. As such, Bare XML is extremely fast and simple. Currently, the parser is available in a perl module with Perl glue to turn the created tree into a Perl hash tree. The module name is XML::Bare.

BibTeX bibliographies can be imported, and selected references can be exported to BibTeX, Ris, and DocBook format.
