David,

Thanks for your informative answer and suggested template.

I've just tried it, but it doesn't appear to be working.  Here is what I
am using (modified slightly for my schema):

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:aston="http://www.aston.tv/schemas/Aston/Aston7";>

   <xsl:output method="xml" indent="yes"/>

   <xsl:template match="node()">
       <xsl:copy>
           <xsl:copy-of select="@*"/>
           <xsl:apply-templates select="node()[1]"/>
       </xsl:copy>
       <xsl:apply-templates select="following-sibling::node()[1]"/>
   </xsl:template>

   <xsl:template match="aston:offset[not(node())]">
       <xsl:param name="a" select="/.."/>
       <xsl:choose>
           <xsl:when test="following-sibling::node()[self::* or
normalize-space(.)][1]/self::aston:offset[not(node())]">
               <xsl:apply-templates
select="following-sibling::aston:offset[1]">
                   <xsl:with-param name="a" select="$a|@*"/>
               </xsl:apply-templates>
           </xsl:when>
           <xsl:otherwise>
               <offset x="{sum($a[name()='x']|@x)}"
y="{sum($a[name()='y']|@y)}" z="{sum($a[name()='z']|@z)}"/>
               <xsl:apply-templates select="following-sibling::node()[1]"/>
           </xsl:otherwise>
       </xsl:choose>
   </xsl:template>

</xsl:stylesheet>

Here is the exact XML I am trying it on:

<text xmlns=\"http://www.aston.tv/schemas/Aston/Aston7\";>
   <offset x=\"0.1\" y=\"0\" z=\"0\" />
   <offset x=\"0.1\" y=\"0\" z=\"0\" />
   Aston Broadcast Systems Ltd.
</text>

Can you spot any obvious mistakes I may have made?

Regards,

Matt.
