You can get the xml file via Jquery ajax GET request and parse it like this:

$.ajax({
    type: "GET",
    url: "your_xml_file.xml",
    dataType: "xml",
    success: function(xml) {
        $(xml).find('entry').each(function(){
            var circulation = $(this).attr("circulation");
            // Do whatever you want to do with circulation
        });
    }
});

Don't forget that, if there are more than one entry tag in xml, this will read all circulation attributes of those entries, so that you should be aware of how much circulation you want to process.

If you want to take only the first entry, you can use this:

$.ajax({
    type: "GET",
    url: "your_xml_file.xml",
    dataType: "xml",
    success: function(xml) {
        var circulation = $(xml).find('entry').first().attr("circulation");
    }
});

Here are my resources to write this:

Here is an example:

    if (window.XMLHttpRequest) {
      xhttp=new XMLHttpRequest();
    } else {
      xhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xhttp.open("GET","the name of your xml document.xml",false);
    xhttp.send();
    xmlDoc=xhttp.responseXML;
    var circulation = xmlDoc.getElementsByTagName("entry")[0].getAttribute('circulation');
