Example: lr_xml_insert

The following example inserts an "extension" tag to an employee record. It searches the input string xml_input for the tag "<employee>" and inserts an XML fragment which contains the extension information. ("XmlFragment=<extension>2145</extension>").

Note that the Position specification is child, so the inserted string fragment is placed just before the employee tag ends (at "</employee>").

The resulting string is contained in the ResultParam parameter, Result.

For more examples of the use of lr_xml_insert, see the sections Insert an attribute to the root and Insert a child in all elements using a parameter in Example Scripts for XML Queries.
