String buildXml(Node node)
build Xml

StringWriter writer = new StringWriter();
buildXml(node, writer);
return writer.toString();

boolean copyTreeToResult(Node tree, Result result)
Copy DOM tree to a SOAP tree.

try {
 TransformerFactory tFactory = TransformerFactory.newInstance();

 DOMSource source = new DOMSource(tree);
 transformer.transform(source, result);
 return true; 
} catch (TransformerConfigurationException tce) {
 tce.printStackTrace();
...

InputStream createInputStream(Node node)
create Input Stream

ByteArrayOutputStream stream = new ByteArrayOutputStream();
TransformerFactory.newInstance().newTransformer().transform(new DOMSource(node), new StreamResult(stream));
return new ByteArrayInputStream(stream.toByteArray());

String createXML(Node doc)
create XML

TransformerFactory xff = TransformerFactory.newInstance();
Transformer serializer = null;
try {
 serializer = xff.newTransformer();
} catch (TransformerConfigurationException te) {
 throw new RuntimeException("Could not create transformer. " + te.getMessage());
serializer.setOutputProperty(OutputKeys.INDENT, "yes");
...

String getAsText(Node n)
get As Text

try {
 Transformer t = TransformerFactory.newInstance().newTransformer();
 StringWriter out = new StringWriter();
 t.transform(new javax.xml.transform.dom.DOMSource(n), new javax.xml.transform.stream.StreamResult(out));
 return out.toString();
} catch (Throwable t) {
 t.printStackTrace();
 return null;
...

String getHumanReadableXml(final Node node)
Converts the provided DOM Node to a pretty-printed XML-formatted string.

StringWriter toReturn = new StringWriter();
try {
 Transformer transformer = getFactory().newTransformer();
 transformer.setOutputProperty(OutputKeys.INDENT, "yes");
 transformer.setOutputProperty(OutputKeys.STANDALONE, "yes");
 transformer.transform(new DOMSource(node), new StreamResult(toReturn));
} catch (TransformerException e) {
 throw new IllegalStateException("Could not transform node [" + node.getNodeName() + "] to XML", e);
...

String getNodeValue(NodeList nodeList)
get Node Value

final Transformer serializer = TransformerFactory.newInstance().newTransformer();
serializer.setURIResolver(null);
final StringBuilder buf = new StringBuilder();
for (int i = 0; i < nodeList.getLength(); i++) {
 final StringWriter sw = new StringWriter();
 serializer.transform(new DOMSource(nodeList.item(i)), new StreamResult(sw));
 String xml = sw.toString();
 final Matcher matcher = HEADER_PATTERN.matcher(xml);
...

String getValueOfValueNode(Node n, boolean unescape)
Method to get the value of "Value" node If unescape is set to false, xml escaped chars will not be unescaped.

return getValueOfValueNodeNoTrim(n, unescape).trim();

String getXML(NodeList childNodes)
get XML

try {
 StringBuilder builder = new StringBuilder();
 Transformer t = TransformerFactory.newInstance().newTransformer();
 t.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
 for (int i = 0; i < childNodes.getLength(); i++) {
 StringWriter sw = new StringWriter();
 t.transform(new DOMSource(childNodes.item(i)), new StreamResult(sw));
 builder.append(sw.toString());
...

byte[] nodeToByteArray(Node node)
Returns a byte array from given node.

Source source = new DOMSource(node);
ByteArrayOutputStream out = new ByteArrayOutputStream();
Result result = new StreamResult(out);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
transformer.transform(source, result);
return out.toByteArray();
