In 2.0 you don't need the key() function to do this, you can do it using the
idref() function.
If you want to do it using key(), your key definition would work (the value
would be indexed on each string appearing in the @references attribute)
provided you use a schema-aware processor and @references has a list type.
If you want to do it using a 2.0 basic processor, you can specify
use="tokenize(@references, '\s')".
If you want to do it using 1.0, you're a masochist...

Subject: [xsl] IDREFS and key()
I have an element that contains an IDREFS attribute like the
following:
<Attribute id="aAtt" references="foo bar"><Name>Att</Name></Attribute>
The references attribute is defined as an IDREFS and the schema and
document that this lives in are all valid.
I want to use the references attribute in a key definition so
I can reverse
the relationship and in this case from the element identified
as foo or
bar, indicate that the Attribute element, named Att links to it.
My key definition is this:
<xsl:key name="attribute-references" match="Attribute"
use="@references"/>
I process this with a for-each as follows:
<xsl:for-each select="key('attribute-references', $parentElement)>
$parentElement is set to the id value that is in the
references attribute.
In this example when there are multiple values in the
@references, nothing
is found, but if I remove in this case the second value, I
produce results.
It seems like the key() is trying to match my value of 'foo'
against the
complete string of 'foo bar', rather than doing a "contains"
sort of match.
Is this what is expected? When I provide the full 'foo bar'
to the for-each
I now match this Attribute definition.
How do I get the key() function to break up the IDREFS and
process the
individual values? I tried using id() in the key definition
but that didn't
help.
