Using function SUM(node-set) - java.lang.ClassCastException
Hi all,
I've written an XSL that contains this part of algorithm:
...
<xsl:variable name="sum_values">
<val><xsl:value-of select="."/></val>
<val><xsl:value-of select="$sum_value"/></val>
</xsl:variable>
<xsl:value-of select="sum($sum_values/val)"/>
...
when I run the XSLT processor I receive this exception:
Caused by: java.lang.ClassCastException
at
org.apache.xpath.axes.FilterExprIteratorSimple.executeFilterExpr(FilterE
xprIteratorSimple.java:104)
at
org.apache.xpath.axes.FilterExprWalker.setRoot(FilterExprWalker.java:168
)

org.apache.xpath.Expression.executeCharsToContentHandler(Expression.java
:357)

Could you tell me why I receive this exception? I'd like to know if you
have a better solution to solve this matter.
Thanks in advance.
Pier Paolo.

Pier,
this is a known restriction of XSLT 1.0. You are not permitted to have
XPath expressions that apply to a result tree fragment.
It would be better if no exception were thrown, and a meaniful error
message was issued. A bug is already opened for this issue (
http://issues.apache.org/jira/browse/XALANJ-1263 )
In your situation you have a work around with the node set extensions of
Xalan, see http://xml.apache.org/xalan-j/extensionslib.html#nodeset
