I was thinking sequentially...down the elements as
they occur.
When I tried your suggestion the <number> element came
up blank. Did I do this correctly?
XSL:
<?xml version="1.0" encoding="utf-8"?>
<xsl:transform version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" method="xml"
omit-xml-declaration="no"
encoding="UTF-8"/>
<xsl:template match="doc">
<doc>
<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-group>
</doc>
</xsl:template>
</xsl:transform>
XML:
<?xml version="1.0" encoding="UTF-8"?>
<doc>
<level2>
<name>box</name>
<number>1234</number>
</level2>
<level2>
<name attachpart = '1'>washer</name>

</level2>
<level2>

<number>7654</number>
</level2>
<level2>
<name attachpart='1'>screw</name>
<number>345</number>
</level2>
</doc>
OUTPUT:
<?xml version="1.0" encoding="UTF-8"?>
<doc>
<record>
<name>box</name>
<attachingPart/>
</record>
<record>
<name>washer</name>

Thanks for your help.

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

</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.

Hermy
