( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Hi, if I understand your question correct, you want to extract information from each token. So splitting the string into tokens first and then extracting any useful information one by one might be a suitable approach for you?

use strict; sub extract { chomp(my $orig = shift); foreach ( split(/,/, $orig) ) { # scan list of tokens if ( / <\*\d+> ([^<]+) < (\d+) : (\d+) > /x ) { # do something with extracted information print "got $1/$2/$3 from '$orig'\n"; } } } extract($_) while (<DATA>); __DATA__ <*2>H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0> H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0>
Prints:
got H/3/0 from '<*2>H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0>' got I/3/0 from '<*2>H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0>' got Z/2/0 from '<*2>H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0>' got I/3/0 from 'H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0>' got Z/2/0 from 'H<3:0>,<*2>I<3:0>,...,<*2>Z<2:0>'

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.
