Hi All,
I am trying to use key in order to find the distinct parents & their
children. My input xml has the following hierarchy -
ProjectType
Project
Task
My issue is that the xslt I have written picks the distinct project type
& projects properly. However it picks only the first distinct task under
various project but not all the distinct task. I am unable to find my
mistake in the code.
I am using .NET & xslt 1.0.
My input xml is -
<?xml version="1.0" encoding="utf-8"?>
<tnsa:Projects xmlns:tns="http://local/Schema/Finance/Common/1.0";
xmlns:tnsa="http://local/Schema/Finance/ChargeableProject/1.0";>
<tnsa:Project>
<tns:ProjectType>Resources</tns:ProjectType>
<tns:ProjectNumber>JXCS08015</tns:ProjectNumber>
<tns:Task>
<tns:TaskNumber>01</tns:TaskNumber>
</tns:Task>
<tns:Task>
<tns:TaskNumber>01A</tns:TaskNumber>
</tns:Task>
<tns:Task>
<tns:TaskNumber>01A-00</tns:TaskNumber>
</tns:Task>
<tns:Task>
<tns:TaskNumber>01B</tns:TaskNumber>
</tns:Task>
</tnsa:Project>
<tnsa:Project>

</tns:Task>
<tns:Task>
<tns:TaskNumber>01A-00</tns:TaskNumber>

</tns:Task>
<tns:Task>
<tns:TaskNumber>5.1.1</tns:TaskNumber>

</tnsa:Project>
</tnsa:Projects>
I am using the following xslt -
