It would look something like this:
Dom.XmlNode rootElement = this.XML_DOC.getRootElement(); Dom.XmlNode locationElement = rootElement.getChildElement('location', null);String lat = locationElement.getChildElement('lat', null).getText();
String lng = locationElement.getChildElement('lng', null).getText()
