I need to access an xml value by it's position.
can this be done (or is there a better way to do it)
to access the 3rd foo element just do
foo[3]
<xsl:value-of select="../../../columns/column(position())/type"/>
You need square brackets not round, and you want to evaluate position()
in the current node list _before_ you start this xpath as it's the
current position that you want, so
<xsl:variable name="x" select="position()"/>
<xsl:value-of select="../../../columns/column[$x]/type"/>
Of course for $x to have teh right value you need to make sure that your
current node list only has cell nodes, if you just do an
<xsl:apply-templates/>
rather than
<xsl:apply-templates select="cell"/>
on the row element then your current node list will include white space
text nodes and so the position of teh cell elements will be
2,4,6,... not 1,2,3,...
