Hi,

Thank you about XRule,It is so usefull Rule Management.
I have problem with XmlAttribute like this:
<FLN ID="F051601004" SUM="">
<CFLN ID="1">10</CFLN>
<CFLN ID="2">2</CFLN>
<CFLN ID="3">4</CFLN>
</FLN>

I want to calculate sum of CFLN and set it into SUM attribute.

<?xml version="1.0" encoding="utf-16"?>
<xr:rules xmlns:xr="http://www.xrules.org/2003/11">
<xr:ruleset context="/FLN">
<xr:calculate target="SUM">
<xr:value>sum(CFLN)</xr:value>
</xr:calculate>
</xr:ruleset>
</xr:rules>

But when I use this XRule, I get error "Not found SUM,You can use
CreateNode Attribute ...."

How can I set <SUM> XMlAttribute in my XML file.
