Java Utililty Methods XML Element Get Value

Element getTagElement(Element node, String key)
get Tag Element

NodeList childs = node.getChildNodes();
for (int t = 0; t < childs.getLength(); t++) {
 Node attNode = childs.item(t);
 if (attNode.getAttributes() != null) {
 if (attNode.getAttributes().getNamedItem("k").getNodeValue().equals(key)) {
 return (Element) attNode;
return null;

String getTagLocalName(final Element element)
get Tag Local Name

if (element == null) {
 return null;
final String localName = element.getLocalName();
if (localName != null) {
 return localName;
return element.getTagName();
...

String getTagNameIgnorePrefix(Element element)
get tag name without any prefix

if (element == null)
 return null;
String tagName = element.getTagName();
if (tagName.contains(":")) {
 tagName = tagName.split(":")[1];
return tagName;

String getTagText(Element ele)
Scans the tag's children and returns the first text element found

NodeList nl = ele.getChildNodes();
int size = nl.getLength();
Node node = null;
int i = 0;
for (; i < size; i++) {
 node = nl.item(i);
 if (node instanceof Text)
 break;
...

String getTagValue(Element e)
Gets the text value from the specified element.

Node n = (Node) e.getChildNodes().item(0);
if (n == null)
 return null;
return n.getNodeValue();

String getTagValue(Element e, String tag)
get Tag Value

NodeList nlList = e.getElementsByTagName(tag).item(0).getChildNodes();
Node nValue = (Node) nlList.item(0);
return nValue.getNodeValue();

String getTagValue(Element element, String tagName)
get Tag Value

String tagValue = "";
if (element != null) {
 NodeList nodes = element.getElementsByTagName(tagName);
 if (nodes != null && nodes.getLength() == 1) {
 Node node = nodes.item(0);
 tagValue = node.getTextContent();
return tagValue;

String getTagValue(Element element, String tagName)
Retrieve the value of an XML tag.

try {
 NodeList tagList = element.getElementsByTagName(tagName);
 Element tagElement = (Element) tagList.item(0);
 NodeList textTagList = tagElement.getChildNodes();
 return (textTagList.item(0)).getNodeValue().trim();
} catch (Exception e) {
 throw new Exception(
 "Error in parsing the element \"" + element.toString() + "\" with the tag \"" + tagName + "\"");
...

String getText(Element aElement)
Returns a concatenation of all of the text nodes and CDATA nodes that are immediate children of this element.

if (aElement == null)
 return null;
StringBuilder buffer = new StringBuilder();
NodeList nl = aElement.getChildNodes();
for (int i = 0; nl.item(i) != null; i++) {
 Node child = nl.item(i);
 switch (child.getNodeType()) {
 case Node.CDATA_SECTION_NODE:
...

String getText(Element config)
returns the first text child within the node.

if (config == null) {
 throw new IllegalArgumentException("config cannot be null");
NodeList children = config.getChildNodes();
for (int i = 0; i < children.getLength(); i++) {
 if (children.item(i) instanceof Text) {
 return children.item(i).getNodeValue();
return null;
