[xsl] problem defining param value


Subject: [xsl] problem defining param value

Hi everyone,

I have a stylesheet with the following section:

<!-- use the value passed in by parameter if available -->
<xsl:when test=" $OUTSIDE_PARAM != '' ">
<xsl:value-of select="$OUTSIDE_PARAM"/>
</xsl:when>

<!-- if no parameter passed, use 'VALUE3' as a fallback; this is the default value -->
<xsl:otherwise>
<xsl:value-of select=" 'VALUE3' "/>
</xsl:otherwise>


$OUTSIDE_PARAM was originally being defined as "VALUE1" by the xml file that called in the stylesheet, using the following syntax:
<!-- Parameters to pass to the XSLT processor at runtime. -->
<param_set name="stylesheet-parameters">
<param_set_item item_name="OUTSIDE_PARAM" item_value="VALUE1"/>
</param_set>


But I wanted to be able to define $OUTSIDE_PARAM as either "VALUE1" or "VALUE2" depending on another variable. So I added that variable to another stylesheet, which I called in like so:
<param_list name="additional_stylesheets">
<param_list_item item_value="NEW_STYLESHEET.xsl"/>
</param_list>
from the xml file that calls in the first stylesheet, and used the following syntax in the NEW_STYLESHEET.xsl:


<xsl:variable name="fork1">
<xsl:value-of select="string that returns either 'FORK' or 'SPOON'"/>
</xsl:variable>

<xsl:param name="OUTSIDE_PARAM">
<xsl:if test="$fork1 = 'FORK'">
<xsl:value-of select="string that returns 'VALUE1'"/>
</xsl:if>
<xsl:if test="$fork1 = 'SPOON'">
<xsl:value-of select="string that returns 'VALUE2'"/>
</xsl:if>
</xsl:param>

Unfortunately, the stylesheet is no longer recognizing that a param has been defined at all, and is always defaulting to VALUE3, as determined by the "otherwise" section. It seems to think that $OUTSIDE_PARAM is always empty, even though it's not. Am I missing something completely obvious?

Thanks,
Joni
