Subject: Re: [xsl] Using a parameter in a condition From: Ian Lang <ianplang@xxxxxxxxx> Date: Tue, 24 Feb 2004 09:32:58 -0800 (PST) |
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.
