--------------------------------------
Summary: XPointer is not yet supported
Key: XERCESC-2215
URL: https://issues.apache.org/jira/browse/XERCESC-2215
Project: Xerces-C++
Issue Type: Bug
Affects Versions: 3.2.3
Environment: Gentoo Linux
Reporter: John L. Poole
The documentation at http://xerces.apache.org/xerces-c/ states XInclude is
supported:
...
Features
conforms to
...
XML Inclusions (XInclude) 1.0 (Second Edition), W3C Recommendation 15 November
2006
The XInclude specification entitled "XML Inclusions (XInclude) Version 1.0
(Second Edition)" at https://www.w3.org/TR/2006/REC-xinclude-20061115/
specifies at 3.1 xi:include Element
(https://www.w3.org/TR/2006/REC-xinclude-20061115/#include_element):
xpointer
When parse="xml", the XPointer (see [XPointer Framework]) contained in the
xpointer attribute is evaluated to identify a portion of the resource to
include. This attribute is optional; when omitted, the entire resource is
included. The xpointer attribute must not be present when parse="text". If the
xpointer attribute is absent, the href attribute must be present.
In Gentoo Linux, I installed version 3.2.3-r2
[I] dev-libs/xerces-c

Description: A validating XML parser written in a portable subset of C++
I then created two sample files:
red.xml:
<book xmlns:xi="http://www.w3.org/2001/XInclude";>
<chapter>
<title>Red 1</title>
<para>This is red Chapter 1.</para>
</chapter>
<xi:include href="file:///blue.xml" xpointer="blue1" />
</book>
blue.xml:
<book>
<chapter id="blue1">
<title> Blue First Chapter</title>
<para>This is blue first chapter.</para>
</chapter>
</book>
My run failed to resolve the <xi:include> stating "XPointer is not yet
supported":
jlpoole@ares ~/work/xerces $ XInclude red.xml output.xml
Parse red.xml in progress ...
Fatal Error at file file:///blue.xml, line 0, char 0
Message: include element with XPointer specification; XPointer is not yet
supported
finished.
jlpoole@ares ~/work/xerces
I modified red.xml as follows:
<xi:include href="blue.xml" xpointer="blue1" />
ran:
jlpoole@ares ~/work/xerces $ XInclude red.xml output.xml
Parse red.xml in progress ...
Fatal Error at file blue.xml, line 0, char 0
Message: include element with XPointer specification; XPointer is not yet
supported
finished.
jlpoole@ares ~/work/xerces $
copied blue.xml to my apache server, confirmed that Apache serves us blue.xml.
Modified red.xml:
jlpoole@ares ~/work/xerces $ XInclude red.xml output.xml
Parse red.xml in progress ...
Fatal Error at file http://localhost/blue.xml, line 0, char 0
