295-298....now, about keys.... ;^)

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:

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

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
