Use a text editor (or a sed script) in order to replace --- <!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN" "http://www.oasis-open.org/docbook/xml/4.0/docbookx.dtd";> --- by --- <!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN" "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd";> --- in all your V4.1.2 documents. This is possible because DTD V4.2 is compatible with DTD V4.1.2. > Which DTD is XXE using when I made file / new ? V4.2 > Does it depend on the catalogs files ? No, both DTD are referenced in catalog.xml. For the Book and Article templates, it depends on the document type declaration used in document template. For example, this is the Book template included in the DocBook configuration: --- <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN" "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd";> <book> <title></title> <chapter> <title></title> <sect1> <title></title> <para></para> </sect1> </chapter> </book> --- Document type declaration-less templates such as Chapter, Section or Appendix use the following configuration element of docbook.xxe to find their DTDs: --- <dtd publicId="-//OASIS//DTD DocBook XML V4.2//EN" systemId="dtd/V4.2/docbookx.dtd" /> --- You can read docbook.xxe, it is well commented regarding this point.
