Hi,
To add to what others have said, here is how the OP can fix his
problem. (Apologies if this flew by and I didn't see it.)
xsl:when test="string($foo)" will test as Boolean false when the RTF
has a string value of "", and true when it doesn't.
Cheers,
Wendell
<xsl:variable name="foo">
<xsl:choose>
<xsl:when test="$aVar='someFlag'">
<xsl:value-of select="/path/to/some/element"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="/path/to/another/element"/>
</xsl:otherwise>
</xsl:variable>
<xsl:choose>
<xsl:when test="$foo">
<xsl:value-of select="$foo"/>
</xsl:when>
<xsl:otherwise>--</xsl:otherwise>
</xsl:choose>
