"joshua k",
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp .
We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please choose a new name which meets the requirements.
Thanks.

I am not an expert of the field. However, I faced the same situation and had to write an encoding function myself. It replaced all single or double quotation marks in a string with my own strings.
I mean you need a custom designed solution made by yourself. There is no other way out. Just my opinion.

Here are some suggestions -
a) Since ALL attribute values needs to be quoted, you can simply omit the quote while storing and put the quote while restoring.
b) Use some kind of a unique pattern( eg - #*quote*# ) while storing and replace it with the actual quote while retreiving.

This is really more of a database question than one on XML, so I've moved it over. You may want to search the database forum to see if a solution has already been posted, too.

hi
In my application using dom Object i write an flat xml File,
i want to put xml contents inside the database
1)
can i store the xmlcontents directly into databse with out writing in
the Flat File
2)can i store the file as String inside the dataBase instead of
CLOB which is Better?

supportts all database without using SPecific Interface(ex:java.sql.CLOB)
4)is there anyway i can i store the File which should Explictly support all
databases.

I have once written some sample code for this.
I was using LONG datatype of oracle to stored the XML Document.
From Java World
I was using setAsciiStream() method to send the XML Data
I am not sure dont know if thats the best way round.
But it works.

If you go with a varchar datatype where double quotes are acceptable and only single quotes give you a problem, then the trick is to parse it and replace all single quotes with two single quotes. Works for db2. See your database documentation - there is always some way to get quotes stored in there, its just a matter of finding the way your database allows it. I've also found that in using prepared statements, I don't have to deal with this issue anymore - it just handles it the right way. So you may want to give that a try.

USE A PREPARED STATEMENT. Example:

Then the database will deal with the string. The above uses an oracle sequnce, but I'll assume you can conform your code to this...
