The error you are getting at this line, <xsl:with-param
name="attribute" select="$validAttributeType/@base"/>
is because the variable "validAttributeType" is a result tree fragment
(it's a special data type defined in XSLT 1.0), and you are trying to
apply an XPath operation to it; which is not correct.
To my opinion, you need to use an extension function node-set for this
(if you are restricted to XSLT 1.0).
So for example, something like following will work:
<xsl:with-param name="attribute"
select="xx:node-set($validAttributeType)/xsd:restriction/@base"/>
(please bind the prefix xx to the required namespace - please see the
product documentation for this)
With XSLT 2.0, you will not get the error at all, for the operation
you are trying to do (because XSLT 2.0 implicitly treats the contents
of xsl:variable in this case as a node-set).

Hi,
I'm setting a value on a variable using conditions. The variable must be a
node-set so that I can do some processing with it.
<xsl:variable name="validAttributeType">
<xsl:if test="key('allTypes', @type)">
<xsl:copy-of select="key('allTypes', @type)/xsd:restriction"/>
</xsl:if>
<xsl:if test="xsd:simpleType"
<xsl:copy-of select="xsd:simpleType/xsd:restriction"/>
</xsl:if>
</xsl:variable>
The "xsd:restriction" tag has a "base" attribute that I need to access and
send to a template as a parameter.
<xsl:call-template name="trimAttribute">
<xsl:with-param name="attributeName" select="'base'"/>
<xsl:with-param name="attribute"
select="$validAttributeType/@base"/>
</xsl:call-template>
But it gives me a "XSLT Error (javax.xml.transform.TransformerException):
org.apache.xpath.objects.XRTreeFrag" when I try to do
<xsl:with-param name="attribute" select="$validAttributeType/@base"/>
OR
<xsl:with-param name="attribute"><xsl:copy-of
select="$validAttributeType/@base"/></xsl:with-param>
I can print out the variable's contents, which is correct, but I can't seem
to access the attribute. By the way, previously I had this
<xsl:variable name="validAttributeType" select="key('allTypes',
@type)/xsd:restriction"/>
which works! But adding the conditional messed it up. How can I get the same
behaviour as the above line in a conditional variable?
I appreciate any help. Thank you!
