Hi all,

Look at the XML structure below.  I need a business rule that says that
if there is a single Non-Standard item (IsStandard=0) then the Request
as a whole needs to be treated as Non-Standard.  Although, we are
having problems building this rule easily because BRE seems to only
evaluate first IsStandard element.  Does anyone know of a way to
iterate over all of IsStandard elements in the BRE?

<Request>
<Items>
<Item>
<Number>111</Number>
<IsStandard>1</IsStandard>
</Item>
<Item>
<Number>222</Number>
<IsStandard>0</IsStandard>
</Item>
<Item>
<Number>333</Number>
<IsStandard>1</IsStandard>
</Item>
</Items>
</Request>

Hello vt_asparagus@yahoo.com,

You should create a rule that has a 'exists in' predicate.
Use the following Xpath at the left side of this predicate:

/Item[IsStandard=0]

For the right side use:

/Request/Items

This will make the rule engine loop over all the 'Item' nodes inside the
'Items' and check all the is standard nodes.

You build this rule by adjusting the standard XPath statements in the proper
ties
window of you XML schema.

That worked.

The only thing I have now noticed, is that if I create a vocabulary for
that xpath and then drag and drop into my rule, it does not show the
nice vocabulary name.
