Test to see if a string is an XML document or not in jQuery

Question

I have a string that may or may not contain valid xml content. How can I test to see if that particular string is a valid xml document or not? I would prefer this to be in jQuery or just plain javascript.

thanks.

You can try this JQuery code:

function isXML(xml){
    try {
        xmlDoc = $.parseXML(xml); //is valid XML
        return true;
    } catch (err) {
        // was not XML
        return false;
    }
}
