If you want to construct XPath expressions on the fly as strings, you
will need the xx:evaluate() extension which several products (Saxon,
Xalan, ...) offer.

Subject: [xsl] Literals in XSLT
Hello,
I am attempting to write an XML-to-XML filter for document
entries. The user
can filter the XML file by author, title, or type (ps, pdf,
doc, etc).
Structure of xml:
<?xml version="1.0">
<repository>
<so>
<author>Bob</author>
<title>I Like Cheese</title>
<type>pdf</type>
</so>
</repository>
To do it all in one XSL file, I wrote the following:
<xsl:param name="query">'Ruth Ablett'</xsl:param>
<xsl:param name="search-mode">=</xsl:param>
<xsl:param name="sort-by">author</xsl:param>
<xsl:param name="BigQuery" select="concat($sort-by,
$search-mode, $query)"/>
... XSL required stuff...
<xsl:template="/">
<xsl:if test="{$BigQuery}">
<xsl:apply-templates select="so">
... the "so" template has the required stuff to filter the document.
However, the transformer blows up at {$BigQuery}. Can I use
literals {} like
that?
Thanks.
Ruth

"Microsoft's No. 1 product is Windows, which now comes automatically
installed on every computer in the world and many kitchen appliances.
Technically, Windows is an "operating system," which means
that it supplies
your computer with the basic commands that it needs to
suddenly, with no
warning whatsoever, stop operating.
I speak from experience here. Many a time I have spent hours
writing a
serious and thoughtful column on an important issue, only to
have Windows --
which is often referred to as "the French labor union of
software" -- get
into a snit and call a general computer strike that erases
all my work
moments before deadline, leaving me with no choice but to
bang out a highly
inaccurate column such as this one."
