[svg-developers] Re: Help needed....Svg Parsing

[Andreas Neumann]

Hi pradeep,

It would be nice if you wouldn't send your question multiple times. Being 
annoying on this 
list does not increase but decrease chances that you'll get useful answers.

Also, your question seems to be SAX or xerces related, so why not post on these 
lists? I am 
pretty sure that your problem was already dealt with on other emaillists.

Andreas
