Well, there aren't many programming languages that allow a program to read
its own source code, but you're in luck, because XSLT is one of them.
<xsl:value-of select="document('')/*/xsl:variable[(_at_)name='bool']/@select"/>
should do the trick.
The alternative solution to this problem is to have the search conditions
supplied as a string (for example in a stylesheet parameter or a
configuration file) and to use dyn:evaluate() to turn the string into an
expression that you can evaluate.

Subject: [xsl] How to Display as text the select predicates
of apply-templates
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="$bool">
I also want to display the search argument on the output, so
I know what
it was that this output is searching for.
If I use <xsl:value-of select="$bool"/> I just get the text
value of the
first element of the selected set. And if I first define the search
argument as a string with select="'/responses/...... '"
(double-quoting
to make it a string, not a node set), I can display that
easily enough,
but I cannot find a way to make that variable then select a node set.
Seems so simple, and it is so simple that I cannot find it in the
archives. Sorry for such a trivial question.
Many thanks.
