Hello, I am facing the following problem : My files (I am using DocBook as a DTD) : - I have a book.xml file with "book" as the root. - inside that file I have different "part" elements with some entities inside. - these entities are links to external files I want to include in the book.xml file Overview of book.xml : <!DOCTYPE book SYSTEM "file:/C:/Program%20Files/Oxygen/frameworks/docbook/dtd/docbookx.dtd" [ <!ENTITY % global_entities SYSTEM "global.ent"> %global_entities; ]> <book> <part> <title>My first part</title> &chapter1; &chapter2; </part> </book> Overview of chapter1.xml (file related to &chapter1; entity) : <chapter> <title>My chapter 1</title> <para>blablabla</para> </chapter> Overview of chapter2.xml (file related to &chapter2; entity) : <chapter revision="9.1"> <title>My chapter 2</title> <para>blablabla</para> </chapter> My oXygen transformation scenario : - in the "Parameters" window, I added the following entries : Name : "profile.revision" Value : "9.1" - of course I parameterized the docbook xsl as a cascading style sheet to process profile.xsl first The problem is that in the resulting PDF file I have the chapter1.xml file included but not the chapter2.xml file What did I miss ? In general profiling works well, this is the first time I face such a problem.
