Convert String XML fragment to Document Node in Java

Question

In Java how can you convert a String that represents a fragment of XML for insertion into an XML document?

e.g.

String newNode =  "<node>value</node>"; // Convert this to XML

Then insert this node into an org.w3c.dom.Document as the child of a given node?

Answer 1

Element node =  DocumentBuilderFactory
    .newInstance()
    .newDocumentBuilder()
    .parse(new ByteArrayInputStream("<node>value</node>".getBytes()))
    .getDocumentElement();
