rule engine with xml

Danny Doobay — Fri, 26 Oct 2012 11:06:05 GMT

I am validating current row using the code below.

Private Sub CustomersBO_CheckRulesOnCurrentRow(ByVal e As MicroFour.StrataFrame.Business.CheckRulesEventArgs)

If Me.cust_LastName = "" Then

Me.AddBrokenRule(CustomersBOFieldNames.cust_LastName, "Required field.")

End If

End Sub

With every client that we have these rules could be changed. Therefore I am trying to created a rule engine that could pull a xml file like one below and build the rules dynamically.

Does anyone have an idea?

<rule>

<propertyname>cust_LastName</propertyname>

<argument>cust_LastName = ""</argument>

<errormessage>Required field.</errormessage>

</rule>

<rule>

<propertyname>cust_FirstName</propertyname>

<argument>cust_FirstName = ""</argument>

<errormessage>Required field.</errormessage>

</rule>

</bo>
