How to create a document from part (sub tree) of the other document?
document 1.
<?xml version="1.0" encoding="UTF-8"?>
<root>
<meta1>blaa blaa</meta1>
<meta2>blaa2 blaa2</meta2>
<data>
<info>
<name></name>
</info>
</data>
</root>
document 2 shuold be:
<?xml version="1.0" encoding="UTF-8"?>
<data>
<info>
<name></name>

Or can I just remove root and meta elements?

Answer 1

Something like this:DocumentBuilder db = // create a DocumentBuilder;
Document newDoc = db.newDocument();
Node newRoot = // the Element you want to be the root of the new document;
Node root = newDoc.adoptNode(newRoot);
newDoc.appendChild(root);
