content check for web service calls (2)

I have written one way to do the XML content check for web service call:

Here is another simple way to do this in Loadrunner if you find hard to write a Query(Xpath) in lr_xml_find:

Char Position;
......

lr_start_transaction("web service transaction");

web_service_call( "StepName=echo_101",

"SOAPMethod=MyService.MyServiceSOAP12port0.echo",

"ResponseParam=response",

"Service=MyService",

"Snapshot=t1156241380.inf",

BEGIN_ARGUMENTS,

"xml:part1=*******",

END_ARGUMENTS,

BEGIN_RESULT,

"part1/EchoOutput=Param_EchoOutput2",

END_RESULT,

LAST);

//want to match if the response data include Success Key word
Position= (char *)strstr(lr_eval_string("{response}"), "Success");

if (Position!=NULL) {

lr_end_transaction("web service transaction", LR_PASS);

}

else {
lr_output_message("web service call error occured!Help!:)"
}
