RE: String-length

[Thomas Karlsen <ThomasK@xxxxxxxxxxxxxxx>]

Thanks Phil

For information I'm using LotusXSL and XML4J.
Actually I did not need any namespace.
This worked for me:

<xsl:template match="P">
  <xsl:variable name="lengths">
    <xsl:apply-templates select="preceding-sibling::P|." mode="length"/>
  </xsl:variable>
 <b>This para contains: <xsl:value-of select="string-length()"/>
 Total from para number 1 to <xsl:value-of select="position()"/>:
<xsl:value-of select="sum($lengths)"/></b><br/>
<p><xsl:apply-templates /></p>
</xsl:template>

<xsl:template match="P" mode="length">
  <xsl:value-of select="string-length()"/>
</xsl:template>

Thanks for quick response.
