[jira] Created: (XERCESJ-1180) Document root changes indirectly
during DeferredDocumentImpl children modification
Document root changes indirectly during DeferredDocumentImpl children modification
----------------------------------------------------------------------------------
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.

[jira] Resolved: (XERCESJ-1180) Document root changes indirectly
during DeferredDocumentImpl children modification
Posted by "Michael Glavassevich (JIRA)" <xe...@xml.apache.org>.
[ http://issues.apache.org/jira/browse/XERCESJ-1180?page=all ]
Michael Glavassevich resolved XERCESJ-1180.
-------------------------------------------
Resolution: Fixed
There was an assumption in the code that a newly expanded element node must be the root element if none currently exists. Your test proves that isn't always true. I just committed a fix to SVN. Note that you weren't actually using Xerces when you encountered this bug. The com.sun.org.apache.xerces.internal.* classes come from Sun's implementation of JDK 5.0+ and are a fork/derivative of Apache Xerces. If you're looking for a fix there you'll need to pursue it with Sun.
