Question

I have this function where i want to parse the xml with jquery.

function xmlParser(xml) {

     var xmlTitle = xml.data;
     alert($(xmlTitle).find('title'));
}

I want to alert the title of the the xml like this but it doesn’t work. This is what i did, which can be helpful you to see the xml object.

alert(xml); 
alert(xml.data);

xml alerts: [object Object.]

xml.data alerts: <data><title>Hello</title><topic>World</topic></data>

That’s an element with the tag title, which means it’s an object, and alerts can’t show objects, you should use console.log for that. To show the elements text, you could do:

function xmlParser(xml) {
     var xmlTitle = xml.find('title');
     alert($(xmlTitle).text());
}

FIDDLE

If your getting the XML whith a jQuery method that uses $.ajax, it should be parsed already, otherwise a good practice is to parse the XML with $.parseXML to make sure jQuery can treat it the usual way.

function xmlParser(xml) {
     var xmlTitle = $.parseXML(xml.data);
     alert($(xmlTitle).find('title').text());
}

var xml = {}
    xml.data = '<data><title>Hello</title><topic>World</topic></data>';
