How to use the syntax of getxmlWait(); I want to replace the getxml(); with getxml() wait but I am getting confused with the syntax

How to use the syntax of getxmlWait();  I want to replace the getXML(ajaxResponse).; with getXMLWait(). wait but I am getting confused with the syntax.

I know getxml() uses asynchronous call and getXMLWait(). uses synchronous call but all I want is that how shall I replace this code as it has a function call back and in that it checks for various condtions. 

Even though if I replace that with getXML I still want it to check conditions.. but nowhere in the community I found the exact code.. Please help to understand as this is very critical requirement for. 

In a typical example given below.

It's just an example and not the actual requirement. I just want to understand the how the code should be replaced with getXMLWait().

var ga = new GlideAjax('u_getData'); 
	
	ga.addParam('sysparm_name','DbExist');   
	ga.addParam('sysparm_db_name',dbName);  
	ga.addParam('sysparm_sql_server',sqlServer);
	ga.addParam('sysparm_inst',inst);
	
	ga.getXML(ajaxResponse);   
	
	function ajaxResponse(response) {  
	    var answer = response.responseXML.documentElement.getAttribute("answer");
	    if(answer == 'true') { 
			alert("Database already exist"); 
			g_form.setValue("u_dbname","");
			g_form.setValue("u_environment","");
			g_form.setValue("u_server","");
		}
    }

If you must use getXMLWait, this would be the syntax:

var ga = new GlideAjax('u_getData');
ga.addParam('sysparm_name','DbExist');   
ga.addParam('sysparm_db_name',dbName);  
ga.addParam('sysparm_sql_server',sqlServer);
ga.addParam('sysparm_inst',inst);
ga.getXMLWait();   

answer = ga.getAnswer();  //getAnswer() retrieves the result for you
if(answer == 'true') { 
	alert("Database already exist"); 
	g_form.setValue("u_dbname","");
	g_form.setValue("u_environment","");
	g_form.setValue("u_server","");
}

The script would NOT work in either a scoped application or the Service Portal.

Hi Wardeep,

What Jim Coyne, here said is absolutely true. If you are using getXMLWait(), then in order to retrieve your answer/result you will have to call getAnswer().

Please find below link just in case of your reference:
getXML() & getXMLWait()

Please mark my answer as Correct/Helpful in case that helps you.

Thanks
