Subject: Re: = Inserting=20 Data Using SAX

hi there!!

i'm aslo facing simmilar problem !i'm manupulating the XML file = using DOM=20 but i can only find inteface like content handler insax2 to parse and = read the=20 xml file . ilooked at API docs of Sax2 but couldnt find methods = to do=20 so.

Is that so we need any other helper classes or interface = to intsert=20 data in xml file???

If anyone could be precise it would be a great help.
