svn commit: r546623 - /xerces/java/trunk/samples/dom/DOMGenerate.java

[mr...@apache.org]

Author: mrglavas
Date: Tue Jun 12 13:25:08 2007
New Revision: 546623

URL: http://svn.apache.org/viewvc?view=rev&rev=546623
Log:
Modernizing this sample:
- Use the DOM L2 namespace-aware createElementNS() methods instead of the non-namespace-aware DOM L1 methods
- Use the DOM L3 LSSerializer to serialize the document instead of the deprecated native Xerces serializer
