Return Values

All XML functions return the number of matches successfully found or zero on failure.


Input parameters to XML functions with the following names can be parameterized:


function Action(){

   var xmlInput =
       "<employee level=\"manager\">John Smith"+

   var find_cnt;

       lr.saveString(xmlInput, "XML_Input_Param");

       /* Verify that employee John Smith exists */
       find_cnt = lr.xmlFind({xml:'{XML_Input_Param}',
        value : "John Smith", 
        query: "/acme_org/employee" });

       if (find_cnt >0)
       /* Insert John Smith's telephone extension number */
            resultParam :"Result",
            xmlFragment: "<extension>2145</extension>", 
            query :"/acme_org/employee",
            position: "child"} 

           lr.outputMessage(lr.evalString("String after insertion: {Result}"));

       } // end if find_cnt > 0

return 0;
