PTC Advanced Print Publisher can be instructed to recognize XML content. Document properties available to PTC Advanced Print Publisher documents have a direct effect on how PTC Advanced Print Publisher processes XML. Templates can use XPath, or access and manipulate XML DOMs. Transformation of content using XSLT is supported in PTC Advanced Print Publisher.

PTC Advanced Print Publisher includes two XML parsers. Its default parser is based on the libXML library and should always be used. The 3B2–XML parser, which was a home-grown library, should not be used.
