Key: XERCESJ-1180
URL: http://issues.apache.org/jira/browse/XERCESJ-1180
Project: Xerces2-J
Issue Type: Bug
Environment: java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
Reporter: Yury Semikhatsky
In the example below last line causes org.w3c.dom.DOMException because document
root is already defined.
import java.io.ByteArrayInputStream;
import java.io.InputStream;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
public class SetRootTest {
public static void main(String[] args) throws Exception {
DocumentBuilder builder =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputStream inputStream = new
ByteArrayInputStream("<root><a><b/></a></root>".getBytes());
Document document = builder.parse(inputStream);
Element root = document.getDocumentElement();
Element a = (Element) root.getChildNodes().item(0);
document.removeChild(root);
System.out.println(document.getDocumentElement());
a.getFirstChild();
System.out.println(document.getDocumentElement());
document.appendChild(root);//exception here
}
}
The program output:
null
[b: null]
Exception in thread "main" org.w3c.dom.DOMException: HIERARCHY_REQUEST_ERR: An
attempt was made to insert a node where it is not permitted.
