XSL: selecting columns in Excel XML

[Axial]

Question: How to select columns from Excel-generated XML when some cells
are empty.

I've found examples where rows are to be selected, but I can't seem to
extrapolate from that to selecting columns when some cells are empty. Is
there a way to use the ss:Index to account for the missing <Cell elements?

Thank you for any suggestions.

No suggestions? Or is my question confusing, in which case I can try to
elaborate a little more.

Thx

Hi,

Your question was cristal-clear. The solution only proved to be quite difficult.
I have here one type of solution. It uses result tree fragments, so you'd have to declare xsl version 1.1 (which is actually depricated). Tested with Saxon.

use this to recall the price out of column $vColID:

<xsl:attribute name="vPrice">
<xsl:call-template name="FetchRow">
<xsl:with-param name="index" select="$vColID"/>
<xsl:with-param name="row"><xsl:copy-of select="*"/></xsl:with-param>
</xsl:call-template>
</xsl:attribute>

This template must be included:

<xsl:template name="FetchRow">
<xslaram name="index"/>
<xslaram name="row"/>
<xslaram name="offset" select="0"/>
<xsl:variable name="count">
<xsl:choose>
<xsl:when test="$row/ss:Cell[1]/@ss:Index">
<xsl:value-of select="$row/ss:Cell[1]/@ss:Index"/>
</xsl:when>
<xsltherwise>
<xsl:value-of select="$offset + 1"/>
</xsltherwise>
</xsl:choose>
</xsl:variable>
<xsl:if test="$count = $index"><xsl:value-of select="$row/ss:Cell[1]/ssata"/></xsl:if>
<xsl:if test="$count &lt; $index">
<xsl:call-template name="FetchRow">
<xsl:with-param name="index" select="$index"/>
<xsl:with-param name="row"><xsl:copy-of select="$row/ss:Cell[position() != 1]"/></xsl:with-param>
<xsl:with-param name="offset"><xsl:copy-of select="$count"/></xsl:with-param>
</xsl:call-template>
</xsl:if>
</xsl:template>

regards,

It would make more sense if that template 'FetchRow' was called 'FetchColumn'

 

[Axial]

Joris, thank you for your solution. Under any template name ;-) it would
do exactly what I need. Unfortunately I have to use 1.0 and there isn't
a node-set() or nodeset() extension function. After looking at your
example I can certainly see how nodesets are so valuable a concept.

 

[Axial]

I'll run two separate transforms, so that I can use a 1.1 parser for the
first pass, and go back to the 1.0 for the rest of the job.

Thank you again for your assistance.
