Regex

Small sample to replace the regular expression..
Using Core API

String body = "\n";
String out;
Pattern pattern = Pattern.compile("class=\".*?\"");
Matcher matcher = pattern.matcher(body);
out = matcher.replaceAll("");
System.out.println(out);

Using Jakarta ORO

String body = "\n";
String out;
Perl5Util util = new Perl5Util();
out = util.substitute("s/ class=\".*?\"//g", body);
System.out.println(out);
