XmlGetNodeTypedValue Function

Action

Returns the typed value of a node. A Typed value is the text representation of all sub text node values of the passed node. If the node has only a text value - this will be the returned string. If the node has several child nodes, the returned string will be the concatenated string of the text value of the child nodes.
