Dear Luis, Your description of the problem differs clearly from what you put in the Schematron schema. From your description it looks you want <sch:rule context="Root/Element"> <sch:assert test="count(.//Element4)=1">There should be only one element Element4 in Root/Element</sch:assert> </sch:rule> but from your schema it looks like you want <sch:rule context="Root/Element/Element2[@name='Attribute1']/Element3"> <sch:assert test="count(Element4)=1">There should be only one element Element4 in Root/Element/Element2[@name='Attribute1']/Element3</sch:assert> </sch:rule> Best Regards, George -- George Cristian Bina <oXygen/> XML Editor, Schema Editor and XSLT Editor/Debugger http://www.oxygenxml.com Luis Costa wrote:
Hi all,
My goal is to test if there is only one Element4 in each Root/Element.
I try to do this validation with schematron “a” but the result I have got is the wrong one because “a” is testing if there is only one Element4 in all xml “b” and that is not my intend.
Can anyone help me?
a)
<sch:schema xmlns:sch="http://purl.oclc.org/dsdl/schematron">
<sch:title>XXX</sch:title>
<sch:phase id="yyy">
<sch:active pattern="rrr" />
</sch:phase>
<sch:pattern id="rrr">
<sch:rule context="Root/Element">
<sch:assert test="Element2[@name='Attribute1']/Element3/Element4 = 1">Attribute1 shall be single Element4</sch:assert>
</sch:rule>
</sch:pattern>
</sch:schema>
b)
<Root>
<Element>
<Element2 name="Attribute1">
<Element3>
<Element4>Smitty</Element4>
</Element3>
</Element2>
<Element2 name="Attribute2">
<Element3>
<Element4>Cleveland Clinic</Element4>
<Element4>Parma Community</Element4>
</Element3>
</Element2>
</Element>
<Element>
<Element2 name="Attribute1">
<Element3>
<Element4>Dopplemeyer</Element4>
</Element3>
</Element2>
<Element2 name="Attribute2">
<Element3>
<Element4>Cleveland Clinic</Element4>
<Element4>Berea Community</Element4>
