Schematron - Counting number of elements+attributes

[Iwicka]

Hi,

I have a strange problem in schematron - I need to create a role that an element with certain attribute value should occur in the XML exactly once. I created the following rule, but it doesn't show an error when the number of elements with 'en' attributes value is more than 1. However, if I change the constrain to e.g. 3, then it does show en error when there are only 2 of them. What am I doing wrong?

My rule:

Code: Select all

    <sch:pattern>

            <sch:rule context="//description/functionalName/@languageCode">

            <sch:assert test="count(.='en') = 1">The value of Type  must be set to a valid GS1 document name</sch:assert>          

        </sch:rule>

    </sch:pattern>

This doesn't work either:

Code: Select all

    <sch:pattern>

            <sch:rule context="//description">

            <sch:assert test="count(functionalName/@languageCode='en') = 1">The value of Type  must be set to a valid GS1 document name</sch:assert>          

        </sch:rule>

    </sch:pattern>

This XML instance should be incorrect - the name in one language should appear only once:

Code: Select all

<description>

<functionalName languageCode='sv'/>

<functionalName languageCode='sv'/>

</description>

Thanks in advance for any help,

Ewa

Hello,

You can create a rule for the description element that checks the number of functionalName elements that have the @languageCode equal with 'en', something like this:

Code: Select all

<sch:pattern>

    <sch:rule context="description">

        <sch:assert test="count(functionalName[@languageCode= 'en']) = 1">The value of Type  must be set to a valid GS1 document name</sch:assert>         

    </sch:rule>

</sch:pattern>
