Description

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

Method

StringgetTextContent(NodeList nodeList)
get Text Content 
Node node = getFirstNode(nodeList);
if (node == null)
    return null;
return node.getTextContent();
StringgetTextFields(NodeList list)
Extracts all text values from a list of Element nodes. 
StringBuffer sb = new StringBuffer("");
for (int i = 0; i < list.getLength(); i++) {
    Node node = (Node) list.item(i);
    if (i > 0)
        sb.append("\n");
    sb.append(getTextValue(node));
return sb.toString();
...
StringgetXmlNodeValue(NodeList nodeList)
Extract the node string representation. 
String retObj = null;
if (nodeList != null && nodeList.getLength() > 0) {
    Element element = (Element) nodeList.item(0);
    if (element != null && element.getChildNodes() != null) {
        NodeList childNodes = element.getChildNodes();
        if (childNodes != null && childNodes.getLength() > 0) {
            retObj = ((Node) childNodes.item(0)).getNodeValue();
return retObj;
booleanhasElementNodes(NodeList list)
Check whether there are any element nodes in a NodeList 
final int length = list.getLength();
for (int i = 0; i < length; i++) {
    if (list.item(i).getNodeType() == Node.ELEMENT_NODE) {
        return true;
return false;
booleanhasImageNodes(NodeList nodeList)
has Image Nodes 
for (int i = 0; i < nodeList.getLength(); i++) {
    Node n = nodeList.item(i);
    if (n != null) {
        if (n.getNodeType() == Node.ELEMENT_NODE) {
            Element element = ((Element) n);
            String tag = element.getTagName();
            if ("img".equals(tag) || "object".equals(tag)) {
                return true;
...
intindexOf(NodeList nodeList, String tagName, int startIdx)
index Of 
for (int i = startIdx; i < nodeList.getLength(); i++) {
    Node node = nodeList.item(i);
    if (node.getNodeType() != Node.ELEMENT_NODE) {
        if (node.getNodeName().equals(tagName)) {
            return i;
return -1;
booleanisEmpty(@Nullable final NodeList aNL)
is Empty 
return aNL == null ? true : aNL.getLength() == 0;
booleanisEmpty(NodeList nl)
Test if node list is null or empty. 
return nl == null || nl.getLength() == 0;
booleanisListEmpty(NodeList list)
is List Empty 
return list.getLength() == 0;
booleanisNodeListEmpty(final NodeList nodeList)
is Node List Empty 
return nodeList == null || nodeList.getLength() == 0;
