Re: InstantDB: how to replace quotes with " ?


Hi there -- this is more of a general Java question, but
I'll try to help.  You need to employ the StringBuffer's
replace, which will let you replace a substring with
another.  String.replace only works on single chars. 
Here's the contents of a test app, test.java, that
should help.  P.S. I don't guarantee that this is the
most elegant way to do this ... and you could certainly
make a generic replace method that would handle any
substring substitution.  I'll leave that part for you
...   ;-)

Good Luck!
Bill Graham

import java.util.*;

public class test
{
    public static void main(String[] args)
    {
        String str = "This is a \"String\" that I'm
going to work on ...";
        StringBuffer sb = new StringBuffer( str );
        
        System.out.println("Original: " + str);

        int pos;
        while ( (pos = str.indexOf("\"")) > -1 )
        {
            sb.replace(pos, pos + 1, """);
            str = sb.toString();
        }
        System.out.println("Double Quotes Fixed: " +
str);

        while ( (pos = str.indexOf("\'")) > -1 )
        {
            sb.replace(pos, pos + 1, "'");
            str = sb.toString();
        }
        
        System.out.println("Single Quotes Fixed: " +
str);
    }
}
