Recursive XInclusion with XPointer fragment selection fails
Hello!
I have three XML files: "a.xml", "b.xml" and "c.xml". Full XML files are at the end of this message.
1) "c.xml" is simple XML file.
2) "b.xml" does simple XInclusion of "c.xml" as '<xi:include xmlns:xi="http://www.w3.org/2001/XInclude" href="c.xml" parse="xml" />'.
3) "a.xml" does XInclusion of "b.xml" using XPointer as '<xi:include xmlns:xi="http://www.w3.org/2001/XInclude" href="b.xml" xpointer="element(/1/1)" parse="xml" />'.
I want to have "a.xml", which contains part of "b.xml" and whole "c.xml". I am not able to do this. I receive "a.xml" containing part of "b.xml" with just reference to "c.xml" (there is not done XInclusion of "c.xml") ?unparsed "b.xml". I can receive "a.xml" with (whole) "b.xml" and "c.xml", but only if I do not use XPointer. What am I doing wrong? I am using JAXP in Java 1.5.0_02-b09. Can You help me? I tested it in oXygen 7.0 (Java-based XML editor) and I received expected (correct) result.
Thank You for answers. Stepan
