Michal HuniewiczSubject: The document() function inside a loop

Dear All,

I have a foreach loop that I want to sort.

<xsl:for-each select="//Documents/Relationships/Relationship[not(Rubriek=preceding-sibling::Relationship/Rubriek)]/Rubriek">

And this works OK (the weird not thing is a select distinct workaround for XSLT 1.0).

But now I wanna sort it and I want to do it like that:

<xsl:sort select="document($rubriekConfigFileLocation)/RubriekConfig/RubriekOrder/Rubriek[@name=.]/@sortKey" data-type="number" order="ascending" />

and it doesn't work. If, instead of the dot, I provide a rubriek name inside apostrophes (hardcoded) - it works.
The dot is supposed to represent the current node and if I simply display it:
<xsl:value-of select="." />
it works. But inside the select construction of the sort element - it doesn't...

Moreover, if I try to display it like that:

<xsl:value-of select="document($rubriekConfigFileLocation)/RubriekConfig/RubriekOrder/Rubriek[@name=.]/@sortKey" />

it DOES NOT work.

Any ideas? Thanks.

OK so the problem is that here:

<xsl:value-of select="document($rubriekConfigFileLocation)/RubriekConfig/RubriekOrder/Rubriek[@name=.]/@sortKey" />

the dot means... the current node which is Rubriek, and not the current loop node. I would use

<xsl:variable name="rubriekName" select="." />

but I cannot use it before Sort...

FIXED!

Okay just for the record, in case someone has the same problem.

There is a function ready to use in a situation like that called current().

<xsl:sort
select="document($rubriekConfigFileLocation)/RubriekConfig/RubriekOrder/Rubriek[@name=current()]/@sortKey" data-type="number" order="ascending" />
