XPath Formula Builder For XPath 1.0
TIBCO BusinessEvents uses XPath in the XPath Formula Builder, available in the Function Argument Mapper tool. You can use XPath, for example, when defining payloads for events TIBCO BusinessEvents also uses XPath as the language for defining conditions and transformations.
In XPath 1.0 , the XPath Formula Builder opens in a separate window; however, in XPath 2.0, the XPath Formula Builder is part of the Function Argument Mapping wizard. They both function in the same manner with only difference in user interface. See Function Argument Mapping Wizard for XPath 2.0 for more details on XPath Formula Builder for XPath 2.0.
