but the value of the parameter is lost when I go back to queryBuilder:
which is of course the essence of functional programming. When you call
a function f(x,y,z) a result is returned, and the values of x y and z
are used, but x y and z don't change.
You haven't really shown enough information to offer any code changes,
as I can't guess what the input can be.
You say
(the variable names used are the
possible values for the query string elements and are defined
elsewhere).
they would need to be global parameters as they are not declared in this
template.
unrelated (most likely) to your problem, it's rarely necessary to test
strings like this:
="paramQueryMark" select="'false'" />
...
<xsl:if test="$paramQueryMark = 'true'">
xpath has a boolean type which is what you want here:
="paramQueryMark" select="false()" />
...
<xsl:if test="$paramQueryMark">
Usually for this sort of thing you just want something like
<xsl:for-each select="something">
<xsl:choose>
<xsl:when test="position()=1">?</xsl:when>
<xsl:otherwise>&</xsl:otherwise>
</xsl:choose>
generate param=value
</xsl:for-each>
