[libxml++] problems with xmlpp

[Darko M. <da...@uv...>]

Hi,

Recently I started to use libxml++ for more complex xml files and 
stumbled upon problem.
Problem description is:

If xml file has only specified schema files and not DTD files xpath can 
not be used. I there a workaround for this or something else that can be 
done?

I used it, before I used RelaxNG in favour of XML Schemas. I used the
underlying libxml2 code - have a look over here:
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/*checkout*/protosquared/protosqua=
red/src/ConfigFile.cc?rev=3D1.3

And the lines I changed for Relax NG:
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/protosquared/protosquared/src/Con=
figFile.cc.diff?r1=3D1.3&r2=3D1.4

Have a nice day,
 Daniel

Thanks Daniel, but my problem is more complex. I have xml file that 
needs to be validated with 5 schema files.
here is the root element of the file
<manifest xmlns="http://www.imsglobal.org/xsd/imscp_v1p1" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:adlcp="http://www.adlnet.org/xsd/adlcp_v1p3" 
xmlns:imsss="http://www.imsglobal.org/xsd/imsss" 
xmlns:adlseq="http://www.adlnet.org/xsd/adlseq_v1p3" 
xmlns:adlnav="http://www.adlnet.org/xsd/adlnav_v1p3" 
identifier="MANIFEST-6CF68835-9183-7DD5-93E9-46A5952A16A6" 
xsi:schemaLocation="http://www.imsglobal.org/xsd/imscp_v1p1 
imscp_v1p1.xsd http://www.adlnet.org/xsd/adlcp_v1p3 adlcp_v1p3.xsd 
http://www.imsglobal.org/xsd/imsss imsss_v1p0.xsd 
http://www.adlnet.org/xsd/adlseq_v1p3 adlseq_v1p3.xsd 
http://www.adlnet.org/xsd/adlnav_v1p3 adlnav_v1p3.xsd" version="1.3">

If I use default validation of xsi:schemaLocation I get internal error : 
like this

Unimplemented block at ..\xmlschemastypes.c:2156
file:///C%3A/reload/test_scorm/imsmanifest.xml:21: element controlMode: 
Schemas
validity error : Element 'imsss:controlMode', [strict WC]: No matching 
global de
claration available.

I noticed that if file passes validation xpath can be used. In other 
case no.

Of course file is valid, it appears to be limitation of libxml2.

The code I used for automatic validation is this:

I use libxml++ 1.0.04 and libxml2 2.6.19
