Hi Jeffrey,
Thanks for the reply. Following are the answers to your questions :-
1) XML doc has encoding defined as UTF-8. This is the first stmt in the XML
file :
<?xml version="1.0" encoding="UTF-8"?>
2) I am using InputSource with UTF-8 encoding set. Code snippet:
InputSource ipSource = new InputSource();
ipSource.setEncoding("UTF-8");
ipSource.setByteStream( new FileInputStream( new File(inputFile) ) );
parser.parse(ipSource);
3) Oracle totally supports UTF-8. I stored some UTF-8 data before ( using
SQL scripts) and it worked fine.
4) Comig to the important question, do I convert the data to UTF-8 ? Answer
is NO. The apache documentation says that the encoding is "retained" when a
ByteStream is passed in to the parse method (as InputSource). So, the char
array I get in characters call-back method must have char data encoded in
UTF-8. Is it not correct ? Since the parser does not guarantee that entire
char data is sent in a single call back metod call, I am constucting a
String using the char array. And the String constructor does not take the
encoding parameter. Is there any other way I can get String with UTF-8
encoding ? I can not use byte array because if I covert char[] to byte [],
there is a good possibility of data loss. Following is the code in my
characters call back method. So, in essence, I am assuming that the char[]
I get has UTF-8 data. Please suggest if it is not correct ! !
Please note that elementStack is a data structure I am using to store some
data. Pl ignore it.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
public void characters(char ch[], int start, int length) throws
SAXException {
String currData = new String(ch, start, length);
if (elementStack != null) {
XMLElement currElement = (XMLElement) elementStack.peek();
currElement.appendData(currData.trim());
}

Thanks for the help,

So what does your encodingDecl look like if any in your document?
There is no problem with Xerces J parsing UTF8 data.

What do you mean by "save the data", how? Remember that the parser will get
you
back the data as "Java" char (aka Unicode, UTF16). Do you transcode the
data
back into UTF-8
or does Oracle do that?

If you had UTF16 data back from the parser and stored that into a UTF8 I
think that would
be problematic if you don't convert to UTF8.
UTF8 is multibyte , and UTF16 is double byte data. UTF8 and UTF16 from
U+0000 to U+007F
map to each other (more correctly to said Unicode code point map within
that
range to UTF-8,
therefore form some values if they are store directly into a UTF8 data
repository they map
map correctly but data outside this range wll not.

Good assumption since xml parser must be able to read both UTF-8 and UTF-16
documents.

Did you use the InputSource and provided an encoding?

You said that Oracle stores data as UTF-8??? right. You should this
question in a Oracle
discussion group just to be sure.

Yes, try to see first that your data is correctly store as UTF-8 in Oracle.
To test this pick
a multibyte with more than one byte like.
The Russian Sheah, in UTF-8 I think it is "000416" that should be the
value
stored into UTF-8.
The value that the parser will give you back is Ud096 ( why? Because Java
chars are Unicode...).
Hope this helps,
