If the replaceAll function is giving you problems try something similar to this.
private String fixString(String str)
{
    StringBuffer sb = new StringBuffer(str);

    for (int g2 = 0; g2 < sb.length(); g2++)
    {
        if (sb.charAt(g2) == '\"')
        {
            sb.insert(g2, '\\');
            g2++;//do this so you won't get an infinite loop
        }
   }
    return sb.toString();
}
I think this works.

At first I thought of the obvious answer of replacing the \" with a
\\\", but on compiling a test program, that didn't work.

Looking at the javadoc, String.replace takes to chars, not strings, so
concatenating the \" wouldn't work here.

I tried replaceAll, which takes a String regex, String replacement

Here's the test:


public class TestString {
		public TestString() {
				
		} // TestString constructor
		
		public static void main(String[] args) {
				String originalString = "Original \"string\"";
				System.out.println(originalString);
				originalString.replaceAll("\"", "\\\"" );
				System.out.println(originalString);
		} // end of main()
} // TestString


It comiles and runs just fine, and according to the regexp rules
should output what you want, but the output looks like this:


Original "string"
Original "string"


This could be an artifact of the \ being interpreted as another escape
character within the System.out.println.

Of course, the test could be inaccurate because I had to escape the "
character in the originalString definition as well.

It's getting a bit more interesting now! :)
