XPath Data Processor

The XPath data processor extracts data from the source column using an XPath expression.

If the source XML document uses a default name space, you access these nodes using the prefix "p" in you expression. For all other name spaces, use their respective prefix.

XPath, the XML Path Language, is a query language for selecting nodes from an XML document. In addition, XPath may be used to compute values (e.g., strings, numbers, or Boolean values) from the content of an XML document. XPath was defined by the World Wide Web Consortium (W3C).
