Normalizing/Simplify MS-Excel XML

normalizing data
Hi there,

cracking my head on this...
I try to convert an Excel XML Spreadsheet into a simpler format. My first 
attempt works fine (my Excel sheet name is called "Sheet 1") but only when 
all cells are filled (see code below). When cells in Excel are not filled 
Excel XML simply adds a column reference to the next following cell like 

<Cell><Data ss:Type="String">Peter Pan</Data></Cell>
<Cell ss:Index="4"><Data ss:Type="String">Toon</Data></Cell>
<Cell><Data ss:Type="String">Disney</Data></Cell>
<Cell><Data ss:Type="String">USA</Data></Cell>
<Cell ss:Index="11"><Data ss:Type="String">7</Data></Cell>
<Cell><Data ss:Type="String">GA</Data></Cell>

So type of movie is in column 4, the Studio in column 5 and the country in 
column 6.
(Column 2 would have the Male Star and Column 3 the Female, which is empty 
for Toons or Animee, Column 7-10 some more statistical data)

I need:

The field names are in the first row....
What I wonder: how do I get an XPath expression (I guess 
preceding-sibling:: comes into play) that can give me the column name 
based on the last ss:Index and the "distance to it", so I get column 6 for 
Disney, column 7 for USA etc.

So it seems to be the basic axis question: "When within my siblings was 
the last time a attribute of type x appeared and what was the value. The 
what was the value question seems rather simple: select="
The "how many nodes ago" question is where I'm stuck....

Help is greatly appreciated!!!

My template that works for full rows:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="

        <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="
        <xsl:param name="sheetname">Sheet 1</xsl:param>
        <xsl:template match="e:Workbook">
                <xsl:element name="importdata">
                        <xsl:attribute name="type"><xsl:value-of select="
                        <xsl:apply-templates select="
        <xsl:template match="e:Worksheet">
                <xsl:apply-templates select="e:Table"/>
        <xsl:template match="e:Table">
                <xsl:apply-templates select="e:Row"/>
        <xsl:template match="e:Row">
                <xsl:element name="record">
                        <xsl:attribute name="position"><xsl:value-of 
                        <xsl:apply-templates select="e:Cell"/>
        <xsl:template match="e:Cell[e:Data!='']">
                <xsl:variable name="pos" select="position()"/>
                <xsl:element name="field">
                        <xsl:attribute name="name"><xsl:value-of select="
                        <xsl:value-of select="e:Data"/>
        <!-- elements we do not need -->
        <xsl:template match="e:Row[position()=1]"/>
        <!-- First row contains field names -->
        <xsl:template match="*"/>
