[xsl] Incrementing position in the tree midstream (Part 3)

["Durston, Andrew (AGRE)" <andrew.durston@xxxxxxxxxxxxxxxxxxxx>]

Hi Andreas (and all),

What I have is a really flat XML file. "test-plan" is the bottom level. There are several hundred of "object" within "test-plan." Each "object" has 30-40 odd items under it including "objecttext" and the others I mentioned.

However, I will have one or more tables buried throughout the XML. Starting in one instance of "object" and running for 20-30 objects then ending. So my table building routine needs to find the related "objecttext"s in that table but not further instances of tables. I think I can do that by having two tests in the count command you mention --

	count(following::objecttext[.='.0-1.0'])

How would that be written?

	count(following::objecttext[.= 'string1' & 'string2']) ??

And once I have the count, I use that in a for-each from '.' to following less than count, to output the cells?

	<xsl:for-each select=". | following::objecttext[position()&lt; <<insert count command here or a variable??>>]">
						^^ or following-sibling??
		<xsl:copy-of select="."/>
	</xsl:for-each>

Thanks again,
Andrew

ps	This makes my old brain hurt... :)

What exactly do you need?
If, while processing an objecttext node (the objecttext matching template or
an encompassing xsl:for-each) you need the number of objecttexts having a
certain content ('.0-1.0'), that would be

count(ancestor::test-plan/object/objecttext[.='.0-1.0'])

for the number of all preceding- or following objecttexts in the document,
this would become

count(preceding::objecttext[.='.0-1.0'])
count(following::objecttext[.='.0-1.0'])

The *-sibling axes return only nodes from the same object parent (my guess
is that this is one of the things causing your confusion?)

xsl:number offers a very interesting and highly configurable alternative...

For all objecttext nodes in the document, no matter what level
<xsl:number count="objecttext[.='.0-1.0']"
            format="1. " level="any" />

For all objecttext nodes, starting from the current test-plan (if there are
more than one in the document)
<xsl:number count="objecttext[.='.0-1.0']"
            from="test-plan"
            format="1. " level="any" />

This should rid you of having to do the counting yourself (in case there are
more than one test-plan in your source document, the XPath needed to feed to
count() will obviously become more complicated..)

Hope this helps!

Cheers,

Andreas
