It's dangerous to use the word "when" in your problem statement because it
suggests you are thinking in terms of order of execution.
What you've got here is a positional grouping problem:
<xsl:for-each-group select="level2"
group-starting-with="*[not(@attachpart)]">
<record>
<name><xsl:value-of select="name"/></name>
<attachingPart>
<xsl:value-of select="current-group()[(_at_)attachpart]/number"/>
</attachingPart>
</record>
</xsl:for-each>

Subject: [xsl] Select nodes with an attribute but not all the nodes
I am making an XML to XML transform using XSLT 2.0 and Saxon
8B. I need to select certain nodes based on an attribute,
but when I find a node without the attribute I want to stop
selecting nodes even if subsequent siblings have the attribute.
<level2>
<name>box</name>
<number>1234</number>
</level2>
<level2>
<name attachpart="1">washer</name>
<number>234</number>
</level2>
<level2>
<name attachpart="1">screw</name>
<number>345</number>
</level2>
<level2>
<name attachpart="1">bolt</name>
<number>456</number>
</level2>
<level2>
<name>nameplate</name>
<number>9876</number>
</level2>
<level2>
<name>switch</name>
<number>7654</number>
</level2>
<level2>
<name attachpart="1">screw</name>
<number>345</number>
</level2>
The washer screw and bold are attaching parts for the box.
I need to output these in an <attachingPart> element.
<record>
<name>box</name>
<attachingPart>234 345
456</attachingPart>
</record>
Depending on how I approach the code, I get nothing or just
the washer or I get *all* of the parts that have the
attachpart attribute. Is there some way to say stop
selecting attachpart nodes when a level2 doesn't have the
attribute? It's sounds so simple but I'm not getting
anywhere with it.
I've been reading both Michael and Jeni and checking the
archives. Some things look close but I get the same results.
The answer is probably right in front of my face but I've
been looking at it so long I can't see the forest for the trees.
Regards,
Hermy
