[rules-users] Drools rules

[Wolfgang Laun]

This is not a Drools problem, however...

You are using a Domain Specific Language (DSL) to transform rules into
Drools Rule Language (DRL). If you have written the DSL you should know how
it works; if you haven't, then there should be a documentation telling you
what the parameters of
   xpathEquals  "/IATA/messageaudit/@messageVersion" "FSU/13/RCS"
mean, and this would immediately solve your problem. If you had that
documentation (why don't you have it?), it would say that the first
parameter is an XPath expression and the second a value to match at the
location the first expression identifies.

Now, when you use SW using XPath with XML, you should know the basics about
XPath. If you don't - w3c has some good tutorials, see the one on XPath,
here <http://www.w3schools.com/xpath/default.asp>.

The XPath used denotes an attribute and therefore your rules will only work
if messageVersion is an attribute of the element /IATA/messageaudit. In the
second XML, all values are elements below that element.
