Hi John,
I'm so close! All I need to do is find a way to use the
answer_scheme_id attribute instead of that hard-coded '1'. But this
doesn't work:
<xsl:param name="answer_scheme"
select="$answer_schemes[position()=(_at_)answer_scheme_id]" />
Is there some reason I can't get the value of the attribute in the
param element? I know the attribute is there because I do a value-of
right after the parameters.
Within the predicate, the context node is the <answer_scheme> element
that you're looking at, so the path "@answer_scheme_id" is being
interpreted as the answer_scheme_id attribute on that <answer_scheme>
element.
To look at the answer_scheme_id attribute on the <question> element,
which is the current node within the template, use the current()
function as follows:
<xsl:param name="answer_scheme"
select="$answer_schemes[position() = current()/@answer_scheme_id]" />
Alternatively, declare an additional parameter to hold the
answer_scheme_id of the <question> element and then refer to that:
<xsl:param name="answer_scheme_id" select="@answer_scheme_id" />
<xsl:param name="answer_scheme"
select="$answer_schemes[position() = $answer_scheme_id]" />
Cheers,
Jeni
