    if (eElement.getElementsByTagName(sTag).item(0)!=null){
        NodeList nlList = eElement.getElementsByTagName(sTag).item(0).getChildNodes();
        //check if child (nlList) contain something
        if ((nlList.getLength() == 0))//if the content is null
            return "";
        //if child contains something extract the value of the first element
        Node nValue = (Node) nlList.item(0);
            return nValue.getNodeValue();
    }
    return "";
