XML Parsing at 64 bit browser

[JohnJ79]

I have to parse the xml file and it is done well if I have used any of the 32 bit Firefox, but not working well at 64 bit browser. I have used the DOM Parsing in java program. Would be any difference? The error as followsSAX Exception : org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.I have searched the problem in net and somebody said add a space between utf-8 and the prolog.I have tried that too. But still the problem exist. Please suggest me about the real problem.Thanks in Advance.
