[xsl] Problem in define Node-set from variable number of params

["Yang" <sfyang@xxxxxxxxxxxxx>]

Hi,

I have following problems in using variable params to define a node-set
variable
and need your kind advice.

First I use the the variable "condition" which is from a predefined
**select** attribute
and it works fine  when applying it to named template of productset.

But when I use the variable of "condition2" generated from various params
test, it fails.

Please someone offers helpful explanations and solutions.  Thanks.

The portion of xslt codes shown below for your reference;

<xsl:variable name="condition"
select="key('prodCode',$thisPP)[substring(@SalesOrderNo,10,2)=$month]"/>

<xsl:variable name="condition2"><xsl:attribute name="select">
<xsl:choose>
     <xsl:when test="string($office) and
string($month)">key('prodCode',$thisPP)[substring(@SalesOrderNo,1,4)=$office
][substring(@SalesOrderNo,10,2)=$month]</xsl:when>
<xsl:when
test="string($office)">key('prodCode',$thisPP)[substring(@SalesOrderNo,1,4)=
$office]</xsl:when>
<xsl:when
test="string($month)">key('prodCode',$thisPP)[substring(@SalesOrderNo,10,2)=
$month]</xsl:when>
<xsl:otherwise>key('prodCode',$thisPP)</xsl:otherwise>
</xsl:choose></xsl:attribute>
</xsl:variable>

<xsl:call-template name="productset">
<xsl:with-param name="datas" select="$condition"/>   <!--  this one works
with predefined conditions.-->
<xsl:with-param name="datas" select="$condition2"/>  <!--  this created
condition won't work.-->
</xsl:call-template>
