How to test a variable

<xsl:choose>

<xsl:when test="$abc=' ' ">

...false

</xsl:when>

<xsl:otherwise>

...true

</xsl:otherwise>

</xsl:choose>

Is this the correct way to test if variable abc has a value (ie. I want to test if a token has been passed)?

Thanks

' <xsl:when test="$abc != '' ">

' ... do this ...

Try to test for NOT EMPTY. Use the xsl:otherwise for an empty value.
