RE: xsl beginner - sum () dont work

Hi,

Your source is not well-formed XML.

The namespace should be "http://www.w3.org/1999/XSL/Transform"

> <xsl:value-of select="sum(/musik/track/time)" />

xsl:value-of is not an allowed top-level element. Use

  <xsl:template match="/">
    <xsl:value-of select="sum(/musik/track/time)" />
  </xsl:template>

and reread the XSLT spec.
