docbook2texixml converts an XML DocBook document to Texi-XML, an immediate XML document type for converting to Texinfo. This output can then be run through texi_xml to produce actual Texinfo files.
The document in the file xml-document is converted and written to standard output. If xml-document is not given, then the document to convert is read from standard input.
Always validate the input document. Although some docbook2X tools try to be resiliant against unrecognized markup, the behavior when encountering such markup is undefined.
The docbook2X tools do not support all of DocBook, or may produce wrong output or even die with markup that is claimed to be supported. These are bugs and you should nag the maintainer about them.
XML::DOM is slow and takes up a lot of memory, proportional to the input document.
