Method

StringgetType(Element elementType)
get XSI type attribute 
return elementType.getAttribute("xsi:type");
ElementgetUniqueElement(Element root, String elementName)
get Unique Element 
NodeList list = root.getElementsByTagName(elementName);
return (Element) list.item(0);
ElementgetUniqueSubnode(Element rootNode, String name)
get Unique Subnode 
Element result = null;
NodeList childNodes = rootNode.getChildNodes();
for (int i = 0; i < childNodes.getLength(); ++i) {
    Node aNode = childNodes.item(i);
    if (aNode.getNodeType() == Node.ELEMENT_NODE) {
        Element el = (Element) aNode;
        if (name.equals(el.getNodeName())) {
            if (null == result) {
...
StringgetValue(Element e, String tagName)
Given a person element, must get the element specified by the tagName, then must traverse that Node to get the value. 
try {
    NodeList elements = e.getElementsByTagName(tagName);
    Node node = elements.item(0);
    NodeList nodes = node.getChildNodes();
    String s;
    for (int i = 0; i < nodes.getLength(); i++) {
        s = ((Node) nodes.item(i)).getNodeValue().trim();
        if (s.equals("") || s.equals("\r")) {
...
StringgetValue(Element el)
get Value 
if (el != null) {
    NodeList nodes = el.getChildNodes();
    StringBuffer sb = new StringBuffer();
    int length = nodes.getLength();
    for (int i = 0; i < length; ++i) {
        Node node = nodes.item(i);
        String s = null;
        s = node.getNodeValue();
...
StringgetValue(Element element)
get Value 
NodeList l = element.getChildNodes();
StringBuffer s = new StringBuffer();
for (int i = 0; i < l.getLength(); i++) {
    switch (l.item(i).getNodeType()) {
    case Node.TEXT_NODE:
    case Node.CDATA_SECTION_NODE:
        s.append(l.item(i).getNodeValue());
return s.toString();
StringgetValue(Element element)
Get the text value for the specified element. 
if (element != null) {
    Node dataNode = element.getFirstChild();
    if (dataNode != null) {
        return ((Text) dataNode).getData();
return null;
StringgetValue(Element element)
get Value 
return element.getChildNodes().item(0).getNodeValue();
StringgetValue(Element element, String tag)
get Value 
String textValue = null;
NodeList nodes = element.getElementsByTagName(tag);
if (nodes != null && nodes.getLength() > 0) {
    Element childElement = (Element) nodes.item(0);
    Node node = childElement.getFirstChild();
    if (node != null) {
        textValue = node.getNodeValue();
return textValue;
StringgetValue(Element pElement)
returns a XML element value. 
String s = null;
try {
    NodeList nodes = pElement.getChildNodes();
    for (int i = 0; i < nodes.getLength(); i++) {
        s = ((Node) nodes.item(i)).getNodeValue().trim();
        if (s.equals("") || s.equals("\r"))
            continue;
} catch (Exception ex) {
    throw new Exception(ex.getMessage());
return s;
