You did nothing wrong. I'm really sorry but you face a (documented) *regression* of XXE v4:
Excerpts of Changes, 4.0 (July 21, 2008), Regressions, http://www.xmlmind.com/xmleditor/changes.html : --- References to external entities can no longer be used to compose modular documents. --- This implies that, for example, a chapter intended to be referenced as an external entity and as such, having no <!DOCTYPE>, is no longer recognized as being a DocBook document. Because it is no longer recognized as being a DocBook document, the chapter is no longer automatically associated to the DocBook DTD and to the DocBook CSS[*]. We definitely gave up the support of authoring modular document using the references to external entities mechanism. We do not intent to remove this regression in the future. We are aware of the inconvenience this severe regression causes to many users and we apologize for this. In order to solve your problem: * You'll have to downgrade to XXE v3. * OR You'll have to use a text editor to convert all your references to external entities to XIncludes as explained here: Porting to XInclude, http://www.xmlmind.com/xmleditor/changes.html#porting_to_xinclude (While at it, why not convert your document to DocBook 5?) * OR You'll have to switch to another XML editor. Many other XML editors support out of the box modular DocBook 4 documents built using references to external entities. I mean, you are not stuck with proprietary software. --- [*] The stock DocBook 4 configuration contains the following detect configuration element and contains no dtd configuration element at all: --- <detect> <and> <rootElementNamespace xsi:nil="true" /> <dtdPublicId substring="true">DTD DocBook</dtdPublicId> <not> <dtdPublicId substring="true">Simplified</dtdPublicId> </not> </and> </detect> --- If you add the following detect and dtd configuration elements to your DocBook 4 customization (~/.xxe4/addon/config/Docbook/docbook.xxe), this will override the stock detect element and this will restore, to certain extent and without support from XMLmind, XXE v3 behavior: --- <detect xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <and> <rootElementNamespace xsi:nil="true" /> <not> <dtdPublicId substring="true">Simplified</dtdPublicId> </not> <or> <dtdPublicId substring="true">DTD DocBook</dtdPublicId> <and> <schemaType xsi:nil="true" /> <or> <rootElementLocalName>part</rootElementLocalName> <rootElementLocalName>chapter</rootElementLocalName> <rootElementLocalName>refentry</rootElementLocalName> <rootElementLocalName>appendix</rootElementLocalName> <rootElementLocalName>glossary</rootElementLocalName> <rootElementLocalName>section</rootElementLocalName> <rootElementLocalName>sect1</rootElementLocalName> <rootElementLocalName>sect2</rootElementLocalName> <rootElementLocalName>sect3</rootElementLocalName> <rootElementLocalName>book</rootElementLocalName> <rootElementLocalName>article</rootElementLocalName> </or> </and> </or> </and> </detect> <dtd publicId="-//OASIS//DTD DocBook XML V4.5//EN" systemId="xxe-config:docbook/dtd/V4.5/docbookx.dtd" /> --- See http://www.xmlmind.com/xmleditor/_distrib/doc/configure/detect.html See http://www.xmlmind.com/xmleditor/_distrib/doc/configure/dtd.html Sundial Services wrote: > I have built a large Docbook reference-manual document with hundreds > of function-definition pages that have each been stored as separate > XML files which are referenced by the master document.
