RE: Defining a key on a RTF inside a Template

2004-12-08 05:14:00
The key() function selects nodes in the document that contains the context
node. So if the context node is a node in the RTF, the key() function will
search the RTF.

The easiest way of ensuring this in XSLT 1.0 is to use something like:

<xsl:for-each select="xx:node-set($rtf)">
  <xsl:value-of select="key('k', 12345)"/>
</xsl:for-each>

Michael,
       I am afraid if I understood your suggestion
correctly.
My key is associated with RTF "projectSum". The I am
wodering how I can use "projectSum" RTF in my key.
"projectsum" is a node in "projectSum" RTF variable.

The value of the match attribute must be a valid

match="exslt:node-set($projectSum)/projectsum"

should simply be

match="projectsum"

The xsl:key declaration doesn't define which
document the key is referring
to; that's decided at the time you use the key()
function.

I am quite agree with Michael because my key
depends
upon an RTF. So I can take that RTF is the context
node for declaring key.

In either case, I am getting error during
processing.
In XALAN : "Incorrect place of defining key"
In SAXON 8.1.1: XPath syntax error at char 0 in
{exslt:node-set($}:;     The only functions
allowed in
a pattern are id() and key()

I too tried to declare the key at the top of my
stylesheet but it still throw error.

Ranjan

According to XSLT 1.0 specificatoion ( 
http://www.w3.org/TR/1999/REC-xslt-19991116 ),
xsl:key is a
top-level element. Therefore you cannot place
it
outside a 
xsl:stylesheet/xsl:transform .
The easiest solution: do not use keys.

No, it's perfectly OK to use keys to search
within
an RTF.

I am creating  a key inside a template with

            <xsl:variable name="projectid"

select="count(key('ProjectPartNumber',$projectref))"/>
                    </projectsum>
            </xsl:copy>
    </xsl:for-each>
</xsl:variable>

<xsl:key name="countDetail"

match="exslt:node-set($projectSum)/projectsum"
use="./@id"/>

In XALAN it throws error with message
"Incorrect
place
of defining Key".
I am not sure whether it is possible to
create a
key
with RTF within a template?
If not possible, is there any otherway to
achive
the
same functionality?

Ranjan
