( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hello, I'm in need of some regular expression help.

I'd like to create a regular expression that would match the following strings:

<*2>H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0>
H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0>

So the <*K> is optional in each string and there could be numerous tokens (seperated by commas).

I have the following:
$str =~ /<\*\d+>([^<]+)<(\d+):(\d+)>,<\*\d+>([^<]+)<(\d+):(\d+)>/
but this will only match
<*K>A<N:M>,<*K>B<N:M>
and not
A<N:M>,<*K>B<N:M>.

Is such a regular expression possible?

Thanks!

Title:
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.
