Re: [xsl] Finding Any Occurrance

["Jay Bryant" <jay@xxxxxxxxxxxx>]

Hi, Bob,

A trick that you'll quickly master is creating what I call an "anchor
variable" whenever you need to hang on to the current context. Consider the
following block of XSLT:

<xsl:template match="widget">
  <xsl:variable name="this-context" select="."
  <xsl:for-each select="/doc/some-other-widget">
    <!-- Get the value of the current context -->
    <xsl:value-of select="."/>
    <!-- Get the value of the saved context -->
    <xsl:value-of select="$this-context"/>
  </xsl:for-each>
</xsl:template>
