How to create xml Document using result of XPath

I'm reading xml document using XPath and I need to create a Document object using the result of XPath evaluation. Can some one tell开发者_运维技巧 me how to do this??

Assuming that your xpath returns a single node, you can do something like:

Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
doc.appendChild(doc.importNode(xpathResult, true));

If it returns a node set, you will have to create a root element yourself.

Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
doc.appendChild(doc.createElement("root"));
for (int i = 0; i < nodeList.getLength(); i++) {
    Node node = nodeList.item(i);
    doc.getDocumentElement().appendChild(doc.importNode(node, true));
}
