heyho,
have a XML like:


<DNgV>

<DeviceTest name="test1" type="Test" spec="harddisc">

        <parent name="ptest1" type="Test" spec="pci">

            <parent name="pptest1" type="Test" spec="pci">



...

I use Schematron Validation and want to test, if DeviceTest-name attribute is unique. Means no other DeviceTest-name and no other parent-name should have the same string.

In schematron i wrote following:

Code: Select all


        <iso:pattern id="uniqueness.DInvDeviceTest">

            <iso:rule context="//dnv:DeviceTest/@name">

                <iso:assert test="count(//dnv:DeviceTest/@name[. = current()]) = 1">

                    Attribute is not unique in 'DeviceTest'

                </iso:assert>

                <iso:assert test="count(//dnv:parent/@name[. = current()]) = 1">

                    Attribute is not unique 'parent/DeviceTest'

                </iso:assert>

            </iso:rule>

        </iso:pattern>

This Schematron works for the test if another DeviceTest has the same name. But i can't figure out why the second test allways leads to an error. what's wrong here?

For a unique DeviceTest/@name value you need to test in the second assert that there is no parent element with the same name attribute as the one matched by the context attribute:

Code: Select all

      <assert test="count(//dnv:parent/@name[. = current()]) = 0">

          Attribute is not unique 'parent/DeviceTest'

      </assert>
