error while validating xml file.

[raghuveer mandal]

Hai all,
I am getting following exception when i am trying to validate an xml document using DOM PARSER.
Failed to validate the XML. org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0xff) was found in the prolog of the document.

Thanks in advance.

That is pretty self explanatory - XML expects to see only valid Unicode characters. Possible sources of invalid characters that I can think of right off-hand:
1. MS Word "smart" punctuation where text is cut and pasted from a Word DOC into XML.
2. Reading the input file with the wrong character encoding.

A programmer's editor that can show Hex values of characters is invaluable in tracking down this sort of thing. I use UltraEdit-32 - it is not free but for something I use all the time it is worth evey dime.
