GetChild
Scans for a direct child datapoint of the current datapoint, by namespace and local name.
If a schema component has elements that contain mixed content, each displays an additional child node - text(). To retrieve the datapoint of a text() node, you will have to pass an empty string in strNamespace as well as "#text" in strLocalName and eSearchDatapointElement in searchFlags.
