[strovo]

I am using firefox to read XML files.But my firefox is not rendering the xml file properly.What could be the problem?Posting the XML below(sample):\[code\] <?xml version="1.0" encoding="utf-8"?><ExtPostTransaction><TransactionInfo><UserID>us</UserID><Password>pwd</Password><ServiceCode>1010</ServiceCode><TransactionID>T20120518091833</TransactionID></TransactionInfo></ExtPostTransaction>\[/code\]My firefox shows it as,\[code\]uspwd1010T20120518091833\[/code\]I am expecting this,\[code\]<ExtPostTransaction> <TransactionInfo> <UserID>us</UserID> <Password>pwd</Password> <ServiceCode>1010</ServiceCode> <TransactionID>T20120518091833</TransactionID> </TransactionInfo></ExtPostTransaction>\[/code\]
