Using the Util.split() method

["Sharpe, Cassandra" <ca...@merck.com>]

I am trying to split pipe delimited text using the Util.split() method.
However, instead of splitting the string based upon the pattern, it is
splitting the string along every character.  I included a code example
below.  When I split the pipe delimited string, I get 39 results.  When I
split the comma delimited string, I get 7 results, which is what I want.
Does anyone have any suggestions?

Thank You,
Cassandra


 import org.apache.oro.text.regex.*;
 import java.util.ArrayList;

public class TestSplit {


  private static String pipes = "E|1|1|abdomen|abdomen|abdomin|abdomin";
  private static String commas = "E,1,1,abdomen,abdomen,abdomin,abdomin";

  public TestSplit() {}

  public static void main( String[] args )throws Exception {

    ArrayList results = new ArrayList();

    Pattern commaPattern = null;
    Pattern pipePattern = null;

    PatternMatcher matcher = new Perl5Matcher();
    PatternCompiler compiler = new Perl5Compiler();


    pipePattern = compiler.compile("|");

    commaPattern = compiler.compile(",");

      Util.split(results, matcher, commaPattern, commas,  Util.SPLIT_ALL);
      System.out.println("Number with commas: " + results.size());

      results.clear();

      Util.split(results, matcher, pipePattern, pipes,  Util.SPLIT_ALL);
      System.out.println("Number with pipes: " + results.size());
  }
}

Cassandra,

The pipe is a special regular expression character. If you escape the pipe
(as I did in the attached file) you'll get the results that you expect.


   % java TestSplit
   Number with commas: 7
   Number with pipes: 39
   Number with pipes (escaped) : 7


Cheers,

Ed.
