Re: Using a parameter in a condition

That's what I thought.  So I added a <xsl:message> to
see what the result of the look up was and realized
that the logic to check for missing value was messing
up the whole thing:

  <xsl:template name="getLocalizedString">
    <xsl:param name="key"/>
    <xsl:variable name="lookupString"
select="$stringTable/strings/string[@key=$key]"/>
    <xsl:message><xsl:text>   In getLocalizedString
value of lookupString is: '</xsl:text><xsl:value-of
select="$lookupString"></xsl:value-of><xsl:text>'</xsl:text></xsl:message>
    <xsl:choose>
      <xsl:when test="lookupString != ''">
        <!-- Return the found string -->
        <xsl:value-of select="$lookupString"/>
      </xsl:when>
      <xsl:otherwise>
        <!-- Return a string indicating what key could
not be found -->
        <xsl:text>!</xsl:text><xsl:value-of
select="$key"/><xsl:text>!</xsl:text>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

Notice the lack of a '$' in front of what I meant to
be a variable name in the test:
      <xsl:when test="lookupString != ''">
changing to
      <xsl:when test="$lookupString != ''">
makes it all work.

Thanks for the help,
