Re: problem using self::node() in for-each

Hi Garrett,
  Please try -

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" version="1.0"
encoding="UTF-8" indent="yes"/>
	
<xsl:template match="/root">
    <xsl:for-each
select="information[@type='info']/instance">
      <xsl:variable name="source-id"
select="inf_source_id" />
      <xsl:value-of select="inf_text" /> -
<xsl:value-of
select="/root/information[@type='source']/instance[inf_source_id
= $source-id]/inf_name" /><xsl:text>&#xa;</xsl:text>
    </xsl:for-each>
</xsl:template>
	
</xsl:stylesheet>

Regards,
Mukul
