fastQuery | The Fast Query on the input string xml.
value | The string to find. This can be the element value or its attribute value.
valueParam | The parameter name containing the string to find.
selectAll | If "yes", all elements matching the query will be processed. If "no", only the first query match will be verified. Default is "no". See Multiple Query Matching.

The lr.xmlFind function queries the XML input string XML for values matching the Query criteria (Value or ValueParam) and returns the number of occurrences. If SelectAll is "no", lr.xmlFind returns either 1 or 0.

## Return Values

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

## Parameterization

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

- XML

- Query

- Value

- XmlFragment

## Example

    function Action(){

       var xmlInput =
       "<acme_org>"+
           "<employee level=\"manager\">John Smith"+
           "<cubicle>227</cubicle>"+
           "</employee>"+
           "</acme_org>";

       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 */
           lr.xmlInsert({xml:"{XML_Input_Param}",
                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;
    }
