[pradeep sd]

Hi All,
   
  Am able to parse svg and traverse through dom tree..The problem is when an 
non svg element is encountered(like <Segments></Segments> or <Planes></Planes> 
its giving exceptions.I dont know how to overcome this problem..plz any help 
me...its urgent...
   
  Sample code i used:
   
  class CreateSvgDom
{
 
 private String parser;
 private SAXSVGDocumentFactory fact;
 private SVGDocument doc; 
 
 public SVGDocument createMethod(String uri)
 {
  try
  {
   parser = XMLResourceDescriptor.getXMLParserClassName();   
   fact = new SAXSVGDocumentFactory(parser);
   fact.setValidating(false);
   doc = fact.createSVGDocument(uri);
   
  }
  
  catch(Exception e)
  {
   e.printStackTrace();
  }
  return doc;
 }
 
}
   
  Errors am getting: 
   
  org.w3c.dom.DOMException: The current document is unable to create an element 
of the requested type (namespace: http://www.w3.org/
