If I understand your question right, you are reading "Learning Perl", but find the chapter about regular expressions too difficult, so that you can't understand it, and you are now looking for an easier introduction. Correct?

I think a VERY easy intro can be found here: http://www.somacon.com/p127.php. After you understood this, go back to your book and read the chapter again. This is another introduction: http://www.enginsite.com/Library-Perl-Regular-Expressions-Tutorial.htm. Though this is on about the same level than the chapter in Learning Perl, maybe it helps you to have the same subject covered in a different way.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
