    If you are sure, that there is only one Common element, and all its childs are Groups, than 

    NodeList common = docEle.getElementsByTagName("Common");
NodeList nl = common.item(0).getChildNodes();

    If not, use the more general solution with xpath:

    XPathFactory xpathFactory = XPathFactory.newInstance();
XPath xpath = xpathFactory.newXPath();
NodeList nl = (NodeList) xpath.evaluate("Common/Group", docEle, XPathConstants.NODESET);
