Hi,
I am using xslt to search an xml file of resonses to a
survey. I want to
display the search predicates at the top of the results of
the search.
How do I get at the text of the search to show what the argument was
that produced the result which I am displaying?
I put the search into a variable at the top of the xslt file:
<xsl:variable name="bool"
select="/responses/response[section/number_sewn > 3]"/>
And then use it
<xsl:apply-templates select="$bool">
And this works the way you want to?
I also want to display the search argument on the output, so
I know what
it was that this output is searching for.
If I use <xsl:value-of select="$bool"/> I just get the text
value of the
first element of the selected set. And if I first define the search
xsl:value-of will extract the string value of the result of evaluating the
expression <http://w3.org/TR/xslt#value-of>. In you case, the result is a
node-set. Extracting the string value of a node-set will retrieve the string
value of the first element in document order
<http://www.w3.org/TR/xpath#function-string>. Use e.g. xsl:for-each to go
throught the node-set bound to $bool, and there extract the value of the
current node.
Cheers,
Jarno
