org.xml.sax.SAXParseException: Unexpected token while parsing XML

Update:- Seems like I have to give the URL which is returning me the xml. Here it is - URL

I am getting SAXParseException when parsing an xml. The xml I am trying to parse is as follows -

<?xml version="1.0" encoding="utf-8"?>
<markers xmlns="">
    <marker name="" address1="" address2="" region="" country="" zip="" imgsrc="" lat="" lng="" distance="" />
    <marker name="" address1="" address2="" region="" country="" zip="" imgsrc="" lat="" lng="" distance="" />
    <marker name="" address1="" address2="" region="" country="" zip="" imgsrc="" lat="" lng="" distance="" />
    <marker name="" address1="" address2="" region="" country="" zip="" imgsrc="" lat="" lng="" distance="" />
    <marker name="" address1="" address2="" region="" country="" zip="" imgsrc="" lat="" lng="" distance="" />
</markers>

The code which I am using to parse this xml is as follows -

public Document getDomElement(String xml) {
    Document doc = null;
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    try {

        DocumentBuilder db = dbf.newDocumentBuilder();

        InputSource is = new InputSource();
        is.setCharacterStream(new StringReader(xml));
        doc = db.parse(is);

    } catch (ParserConfigurationException e) {
        e.printStackTrace();
        Log.e("ParserConfigurationException: ", e.getMessage());
        return null;
    } catch (SAXException e) {
        e.printStackTrace();
        Log.e("SAXException: ", e.getMessage());
        return null;
    } catch (IOException e) {
        e.printStackTrace();
        Log.e("IOException: ", e.getMessage());
        return null;
    }
    return doc;
}

I am using same code to parse other xml data and it works. I couldn't understand what's there in this xml data which is stopping it to parse the data properly. I have checked the xml with many xml validators online too.

I must be missing something obvious here.

EDIT:- The xml I am trying to parse is from a webservice(the name, address etc. are not actually empty). When I try to use the xml directly by hardcoding in the code itself, it works fine. But when trying to use it directly from webservice response, is not working for me.

The exception:-
