While XXE carps on and does not resolve XIncludes using the XPointer scheme, they are preserved and round-tripped, as far as I can see. That is, while you can't see and edit the resulting infoset in XXE, you can at least edit the XPointer expression.
I customized the DocBook XML V4.2 DTD to allow xi:include at appropriate places, and also included the EBNF customization. XXE appears to work with this without further costumization, even display EBNF productions in a very nice style :). My only problem has been that XXE appear to have an internal declaration of the xi:include element similar to the first http://www.w3.org/2001/XInclude version, while I use the http://www.w3.org/2001/XInclude that is now a recommendation (per 20th December 2004). If I want to be able to add xi:include elements in XXE, I must put an 'new' xi:include declaration in the internal subset of the document: <!ELEMENT xi:include (xi:fallback?)> <!ATTLIST xi:include xmlns:xi CDATA #FIXED "http://www.w3.org/2001/XInclude"; href CDATA #IMPLIED parse (xml|text) "xml" xpointer CDATA #IMPLIED encoding CDATA #IMPLIED accept CDATA #IMPLIED accept-language CDATA #IMPLIED > Otherwise, XXE inserts xi:include elements based on the 'old' http://www.w3.org/2001/XInclude (see http://www.w3.org/TR/2002/CR-xinclude-20020917/): <!ELEMENT xi:include (xi:fallback)> <!ATTLIST xi:include xmlns:xi CDATA #FIXED "http://www.w3.org/2001/XInclude"; href CDATA #REQUIRED parse (xml|text) "xml" encoding CDATA #IMPLIED > kind regards Peter Ring > -----Original Message----- > From: xmleditor-support-bounces at xmlmind.com > [mailto:xmleditor-support-bounces at xmlmind.com]On Behalf Of Hussein > Shafie > Sent: 21. januar 2005 10:25 > To: Reiner Schlenker > Cc: xmleditor-support at xmlmind.com > Subject: Re: [XXE] XPath-Expressions with XInclude and XPointer > > > Reiner Schlenker wrote: > > is it possible in XXE to reuse fragments of XML-documents > by adressing them > > with XPath-expressions in the Xpointer-statement?
