Team member during the design phase of the XML DTD, created the original XSLT stylesheet pipeline to convert existing SGML to XML, and provided maintenance of the process until leaving employment with APA in 2006.Since this conversion occured pre-XSLT 2.0, I used Perl and Python scripting to facilitate the conversion of SGML to a well-formed XML format that was then converted through XSLT 1.0 templates.In addition I completed a proof-of-concept Word-to-XML conversion for a fast editing pipeline while at APA. The output available from this pipeline included XML, HTML, and PDF.
