For javascript client using jquery: $.ajax({ type: "POST", url: siteurl+"/webservice/rest/server.php?wstoken="+mytoken, data: data, dataType: 'text', dataFilter: function(data, dataType) { // XML returned by Moodle is not well parsed data = data.replace(/\<VALUE\>/gi,'<VALUE><![CDATA[').replace(/\<\/VALUE\>/gi,']]></VALUE>'); data = data.replace(/\<MESSAGE\>/gi,'<MESSAGE><![CDATA[').replace(/\<\/MESSAGE\>/gi,']]></MESSAGE>'); return data; } , success: function(data) { ....data = $.parseXML(data); // } });

Edit the user linked to the token and set the first name as Noël. Enable mobile web service and also the REST protocol. Use the Javascript-REST demo client ( https://github.com/moodlehq/sample-ws-clients/tree/master/JAVASCRIPT-REST ) and change these lines:   var functionname = 'moodle_webservice_get_siteinfo';   // ....   var data = { wstoken: token, wsfunction: functionname, moodlewsrestformat: 'xml' }   var response = $.ajax( { type: 'POST', data: data, dataType: 'text', url: serverurl, success: function(data) { console.log('Parsed data'); data = $.parseXML(data); console.log(data); } } ); In firebug: no JS errors (mainly an xml parsing error) should appeared. You should be able to see the resulting XML in your JS logs. For 2.0 testing you'll have to create your own service and use moodle_user_get_users_by_id ws function. You'll also have to change these lines:   var functionname = 'moodle_user_get_users_by_id';   // ...   var users = ['2'];   var data = { wstoken: token, wsfunction: functionname, userids: users }   var response = $.ajax( { type: 'POST', data: data, dataType: 'text', url: serverurl, success: function(data) { console.log('Parsed data'); data = $.parseXML(data); console.log(data); } } );
