RE: [xsl] problem with variable and position()

[fe.sola@xxxxxxxxxxxxxx]

Hello Jarno and Michael, thanks for your quick response.
I still have troubles with this template, I realized I can't use a variable on a match 
expression and it is a bad practice to use a global one, re-wrote the template but still 
no good.
The input xhtml documet has several text nodes, one of them starts with the 
word "Description", I should be able to select all the text nodes that have a position 
higher than that one and put it on a single description element.
The templates I rewrote are:
<xsl:template match="body">
     <!-- some templates here for the rest of the text nodes-->
     <xsl:element name="description">
                       <xsl:apply-templates select="text()[starts-with(normalize-space
(),'Description')]"/>
     </xsl:element>
</xsl:template>
<xsl:template match="text()[starts-with(normalize-space(),'Description')]">
                   <xsl:variable name="descPos" select="position()"/> 
                   <xsl:apply-templates select="text()[position()>$descPos]"/> 
</xsl:template>   and hoped the built in templates would work but the <description> tag 
won't get any value after the transformation...
tia, lizet
