Description

The list of methods to do XML Node Value are organized into topic(s).

Method

StringgetValueByTagName(Node n, String tag)
get Value By Tag Name 
if (n == null)
    return null;
if (tag.equals(n.getLocalName()))
    return n.getFirstChild().getNodeValue();
if (n.hasChildNodes())
    return getValueByTagName(n.getFirstChild(), tag);
else if (n.getNextSibling() != null)
    return getValueByTagName(n.getNextSibling(), tag);
...
StringgetValueOfValueNode(Node n)
Method to get the value of "Value" node 
NodeList textNodes = n.getChildNodes();
Node textNode;
StringBuffer value = new StringBuffer("");
for (int j = 0; j < textNodes.getLength(); j++) {
    textNode = textNodes.item(j);
    value.append(textNode.getNodeValue());
return (value.toString().trim());
...
NodegetValues(Node metric)
get Values 
return metric.getFirstChild().getNextSibling();
DoublenodeToDouble(Node node)
Converts a node to a double 
Double returnValue = null;
try {
    String nodeValue = node.getFirstChild().getNodeValue();
    nodeValue = nodeValue.trim();
    returnValue = nf.parse(nodeValue).doubleValue();
} catch (ParseException e) {
    e.printStackTrace();
return returnValue;
voidputAll(final NamedNodeMap dst, final NamedNodeMap src)
Puts all Nodes of the source NamedNodeMap into the destination NamedNodeMap 
final int size = size(src);
for (int i = 0; i < size; i++) {
    dst.setNamedItemNS(src.item(i));
TextsetText(Element parent, String text)
removes all element/text children, then adds a new single text child 
removeChildNodesExceptAttributes(parent);
Document doc = parent.getOwnerDocument();
Text child = doc.createTextNode(text);
parent.appendChild(child);
return child;
voidsetText(Element parentNode, String data)
Sets data to be the TEXT content of element 
if (data == null)
    return;
Text txt = getTextNode(parentNode);
if (txt != null)
    txt.setData(data);
else {
    txt = parentNode.getOwnerDocument().createTextNode(data);
    parentNode.appendChild(txt);
...
voidsetText(Node n, String text)
Sets the text for a node 
if (n == null)
    throw new IllegalArgumentException("Node argument cannot be null");
if (text == null)
    throw new IllegalArgumentException("Node text argument cannot be null");
NodeList nl = n.getChildNodes();
for (int i = 0; i < nl.getLength(); i++) {
    if (nl.item(i).getNodeType() == Node.TEXT_NODE) {
        nl.item(i).setNodeValue(text);
...
TextsetText(Node node, String text)
Creates a Text child, or replaces all existing children of type Text. 
NodeList children = node.getChildNodes();
if (children != null) {
    for (int i = 0, n = children.getLength(); i < n; ++i) {
        Node child = children.item(i);
        if (child instanceof Text) {
            return ((Text) child).replaceWholeText(text);
Text ans = node.getOwnerDocument().createTextNode(text);
node.appendChild(ans);
return ans;
voidsetText(Node node, String text)
set Text 
Text txt = node.getOwnerDocument().createTextNode(text);
node.appendChild(txt);
node.normalize();
