XSL conditional styling based on certain values lower down

[narkusa]

I am trying to create an xsl stylesheet.
Here is how my input XML looks like :-

<diffs>
<test-case number="1">
<diff>
<element>cost-basis</element>
<attribute>at</attribute>
<actual>123</actual>
<expected>234</expected>
<diff-data>
<cost-basis cb="300" key="mykey" is-true="false"/>
</diff-data>
<diff-data>
<cost-basis cb="301" key="mykey" is-true="false"/>
</diff-data>
</diff>
<diff>
<element>adjustment-basis</element>
<attribute>unique-object-id</attribute>
<actual/>
<expected>1.0</expected>
<diff-data>
<cb-adjust-impl id="123456" quantity="100" myid="123456-0-0" />
</diff-data>
<diff-data>
<cb-adjust-impl id="123456" quantity="100" myid="123456-0-0" />
</diff-data>
</diff>
</test-case>
<test-case number="2">
</test-case>
</diffs>

For test case number 1, the id is same irrespective of whether it lies in a different diff-data.
For the first diff-data, the id is not mentioned. Is it possible to go one level higher up and collect the id from either of the subsequent diff-data which has the id attribute and display the value of that id (123456 in this case) for all element in any diff-data for that test case. The output format is not an xml. it is in CSV format.
I tried using ancestor, but not able to get it correctly.
