Example: lr_xml_replace

The following example changes the telephone extension number of an employee from 2145 to 4444. It searches the input string xml_input for the tag "<extension>" and replaces the tag with an XML fragment containing the number 4444 ("XmlFragment=<extension>4444</extension>"). The resulting string is contained in the ResultParam parameter, Result.
