Value of parent element of current-grouping-key()

bonekrusher · September 8th, 2007, 02:57 PM

Hi,

Is it possible to get the attribute value of a parent of a current-grouping-key()?

for example, I have this Xpath expression:

Code:

<xsl:for-each-group group-by="." select="for $w in tokenize(string(.), '\W+') return lower-case($w)">
<xsl:sort select="count(current-group())" order="descending"/>
.......

I want the value of the ../@id

How can I do this?

The items you are grouping (and their grouping keys) are atomic values. Atomic values don't have a parent. So I've no idea what ../@id refers to.

Thank you Michael.

I was trying to get the value of a parent attribute (@id) of the current grouping key...

If Atomic values don't have a parent then what I am trying to do can not work.

Thanks
