Problem in retrieving string with Regex

**Aaliya Seth** · 11-02-2010

Hello,
I know if my piece of code or not and just because I am doing unit testing with selenium and I can not see what is in my variable . So my goal is to retrieve the phrase id = "testcode" given the testcode
Here is my snippet:

Code:

 char A ='"';
Pattern p = Pattern.compiles("^"A + +"$");
String[] m = p.split(id ="testcode");

Thank you in advance for your help

Hello,
I have a code with me, just check it out if it works with you, though I have not tested but I would see something more like AC:

Code:

Pattern p =.compiles("^ id =\\\"(.*)\\\"$");
Matcher m = p.matcher("id =\"testcode\"");
String id = m.group(1);

Hope this will help you and you will find the solution which you are looking for.

Hello,
It works just missing nickel m.matches () before retrieving the data in id.
I have a question: eg I want recuperates in a string in a string of characters such as: the identifier of the button is id = "12304"
I retrieve 12,304. I tried with that but it does not work:

Code:

Pattern p = Pattern.compiles("\\Aid =\"\"\ b") ;
Matcher m = p.matcher("identifier of the button is id =\"12304\"");
m.games();
System.out.print("The result is"+ m.group(0));

Any help on this will be highly appreciated. Thanks in advance.

Hello,
Same method that gave you at the above are good, but with the following pattern, your code will be more productive.

Code:

"^ id =\\\"([^\"]*)\\\".*$"

Just try it with your code and tell me if it worked for you or not. If not then post back with the error and I will try to find a solution for you code. Feel free to post here. Before that you have to try the above pattern, just see if the programs complies and what output you get.

Hello,
I have any alternate solution for this, group (0) it is all chain and group (1) it captures the group (the expression in parentheses). and I made a mistake in my pattern, tried it, I tested it works. Here is the code what I am trying to explain

Code:

      Pattern p = Pattern.compiles("^ .* id =\\\"([^\"]*)\\\".*$") ;
      Matcher m = p.matcher("identifier of the button is id =\"12304\" ");
      m.games();
      System.out.print("The result is" + M.group(1));

Hello,
The following code works for me. I have modified it and if you feel conferable with the code then you can you in your code. Here is the code

Code:

 Pattern p = Pattern.compiles("id =\\\"([^\"]*)\\\"") ;
      Matcher m = p.matcher("identifier of the button is id =\"12304\" id =\"alacon\"");
      int index = 0;
      while (m.find(Index))
      {
        System.out.System.out.println("id =" + M.group(1));
        index = m.end();
      }
