I guess you are trying to use a Transformer to convert a Document to
an xml String? Here's some more quick&dirty code for it:
public String getXml(Node node) {
StringBuilder buffer = new StringBuilder();
if (node == null) {
return "";
}
if (node instanceof Document) {
buffer.append(getXml(((CustomDocument)node).getFirstChild()));
} else if (node instanceof Element) {
Element element = (Element)node;
buffer.append("<");
buffer.append(element.getNodeName());
if (element.hasAttributes()) {
NamedNodeMap map = element.getAttributes();
for (int i = 0; i < map.getLength(); i++) {
Node attr = map.item(i);
buffer.append(attr.getNodeName());
buffer.append("=\"");
buffer.append(attr.getNodeValue());
buffer.append("\" ");
}
}
buffer.append(">");
NodeList children = element.getChildNodes();
for (int i = 0; i < children.getLength(); i++) {
buffer.append(getXml(children.item(i)));
}
buffer.append("</");
buffer.append(element.getNodeName());
buffer.append(">");
} else if (node != null && node.getNodeValue() != null) {
buffer.append(node.getNodeValue());
}
return buffer.toString();
}
