I'm not sure if the leading ..'s in your example are supposed to be part of the keyword or not. If not, as your example shows, try this:

#! /usr/bin/perl

use strict ;
use warnings ;

my @str = ( 'fdjsflsdfjk foo=123 sdjflsdfjklsfj  ',
            'sdfhsdfsd  bar=42 fkjfjklsfjs',
            'zoot=23 ff   ',
            '              nooka=9 '
      ) ;

foreach (@str)
{
    /([[:alnum:]]+)=([[:digit:]]{1,3})(.*)$/ ;
    printf "[%s] [%s] [%s]\n", $1, $2, $3 ;
}
[download]

Output:

[foo] [123] [ sdjflsdfjklsfj  ]
[bar] [42] [ fkjfjklsfjs]
[zoot] [23] [ ff   ]
[nooka] [9] [ ]
[download]

Otherwise, if you want to capture the beginning of the string up to the = sign as the keyword regardless of content, maybe this is what you want:

#! /usr/bin/perl

use strict ;
use warnings ;

my @str = ( 'fdjsflsdfjk foo=123 sdjflsdfjklsfj  ',
            'sdfhsdfsd  bar=42 fkjfjklsfjs',
            'zoot=23 ff   ',
            '              nooka=9 '
      ) ;

foreach (@str)
{
    /^([^=]+)=([[:digit:]]{1,3})(.*)$/ ;
    printf "[%s] [%s] [%s]\n", $1, $2, $3 ;
}
[download]

Output:

[fdjsflsdfjk foo] [123] [ sdjflsdfjklsfj  ]
[sdfhsdfsd  bar] [42] [ fkjfjklsfjs]
[zoot] [23] [ ff   ]
[              nooka] [9] [ ]
[download]

Hope that helps. :-)

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.
