[xml] Using xpointer with xmllint

[stuart shepherd <jonny wark googlemail com>]

Hi

I'm having trouble using xpointer with an xinclude.

Below is an extract of my xml file

<?xml version="1.0"?>

<card

  xmlns:xsl="http://www.w3.org/2001/XMLSchema-instance"

  xsl:noNamespaceSchemaLocation="shema.xsd"

  xmlns:xi="http://www.w3.org/2001/XInclude">

.....

<xi:include href="" xpointer="element(/1/1)"/>

......

</card>

control.xml

<?xml version="1.0"?>

<root>

<control>

    <id>8</id>

    <name>ValidHd</name>

    ......

</control>

</root>

and I validate it with

xmllint --valid --xinclude --schema schema.xsd Xpointer.xml

and that works fine. But when I change the xinclude to 

<xi:include href="" = 'ValidHd'])"/> 

to try and include the control element by name so it's more robust I get the error message "Xpointer.xml:152: element include: Schemas validity error : Element '{http://www.w3.org/2001/XInclude}include': This element is not expected. Expected is ( control ).

Xpointer.xml fails to validate"

And you can see in the output that it hasn't substituted any code in for the xinclude.

What should I be doing?

Is it possible to include elements like this? The name element is unique within the control.xml document, which is why I thought I would be able to include it this way.

Thank you

Stuart.
