I have tried some basic regex but all I seem to be able to do is remove "thispart" and end up with the stuff I don't want.

If you show us the regex that removes "thispart", there are probably lots of Monks here who would be able to teach you how to edit it to make it keep just "thispart". And, as BrowserUK said, supplying a small amount of actual data will help the Monks customize their responses to your actual input data, rather than the alpha-only data you've shown, along with what you expect the output to be given that data.

As a hint while you're reading about perlre: if you create a matching group in your regex, the magic $1 variable will hold the contents of the first matching group; you can use that with a m// to just extract your ID (assuming the "thispart" is really a partial regex that matches what you're looking for), or you could use it with s/// to remove either what matches or remove what doesn't match.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
