 how to assign a NULL to a variable?
HI, guru
Do you know how to assing a NULL to variable in XSL1.0?  Thank you.

My problem is I want write a code as follows, but I do not know how to set a NULL value at the following "otherwise" case:

<xsl:variable name="myvar">
<xsl:choose>
<xsl:when test="conditon a">
<xsl:value-of selcet="xxx"/>
</xsl:when>
<xsl:when test="conditon b">
<xsl:value-of selcet="xxx"/>
</xsl:when>
<xsl:otherwise>
<!-- WANT TO return a NULL value here!!!!! But It return a "" not NULL -->
</xsl:otherwise>
</xsl:choose>
</xsl:variable>


<xsl:if test="$myvar">
.....
</xsl:if>
