RE: [xsl] saxon:evaluate from external to current source

["Michael Kay" <mike@xxxxxxxxxxxx>]

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>
