RE: [xsl] Problem transforming Excel XML Workbook (or how to implement one-more-counter-yet in XSLT)

["Michael Kay" <mike@xxxxxxxxxxxx>]

Yes, Microsoft didn't design this to make your life easy. I think it needs a
sibling recursion something like

<xsl:function name="excel:get-cell" as="element(Cell)?">
  <xsl:param name="row" as="element(Row)"/>
  <xsl:param name="cellNr" as="xs:integer"/>
  <xsl:sequence select="excel:get-sibling-cell(Cell[1], (Cell[1]/@ss:Index,
1)[1], cellNr)"/> 
</xsl:function>

<xsl:function name="excel:get-sibling-cell" as="element(Cell)?">
  <xsl:param name="current-cell" as="element(Cell)?"/>
  <xsl:param name="current-index" as="xs:integer"/>
  <xsl:param name="required-index" as="xs:integer"/>
  <xsl:sequence select="
     if (exists($current-cell)) then
        if ($current-index eq $required-index) then
           $current-cell
        else
           excel:get-sibling-cell($current-cell/following-sibling::Cell,
                    ($current-cell/following-sibling::Cell/@ss:index,
$current-index + 1),
                     $required-index)
    else ()"/>
</xsl:function>

You can do the same thing using recursive templates in XSLT 1.0 if you need
to.
