I'm guessing, but I imagine that the feedback element is the outermost
element of the source.xml document and this is the principal input document
of your stylesheet.
If I've guessed correctly, then you want a global variable
<xsl:variable name="root" select="/">
and you then want to do:
<xsl:for-each select="$formfields/field">
<xsl:variable name="currpath" as="xs:string" select="@srcPath"/>
<xsl:apply-templates select="$root/saxon:evaluate($currpath)"/>
</xsl:for-each>

Subject: [xsl] saxon:evaluate from external to current source
There was a posting in April--see http://www.biglist.com/lists/xsl-
list/archives/200704/threads.html#0022-- in which a question
was posed about establishing proper context for
saxon:evaluate for an
external document. I have a problem that inverts that one somewhat.
I'm working on xsl that uses a reference xml file to direct
the order in which to process a source document. So, when
processing source.xml, I reference an external map.xml, which
looks like this ...
<field-map form="Secondary School Participation"> <field
srcPath="feedback/nameInfo/title"
resId="courtesyTitle">Courtesy Title</field> <field
srcPath="feedback/nameInfo/name"
resId="nameHead">Name</field> <field
srcPath="feedback/nameInfo/email" resId="emailHead">Email</field>
...
</field-map>
The reference map.xml tells me what source nodes to process
in what order. My problem arises when I change context in
the xsl file ...
where $formfields gets me the nodeset from the external
document I want, depending on the form I want to process.
<xsl:for-each select="$formfields/field">
<xsl:variable name="currpath" as="xs:string" select="@srcPath"/>
<xsl:apply-templates select="/saxon:evaluate($currpath)"/>
</xsl:for-each>
... problem is, the saxon:evaluate fails because, I suspect,
I'm in the wrong document context. How can I tell my
apply-templates instruction to evaluate the path in the
source document?
thanks.
Matt.
