I'm going to assume that everything but the anglebrackets is reliably alphanumeric. I shoved $inputexample into $_ to unclutter the code.

use strict;
use warnings;

my $templateformat = 'w<NM>b<NM>cm<CH>sw<SW>';
$_  = 'w8b8cm512swno';
my(@values, @names, $val);

# In the example, @h will be ('w', 'NM', 'b', 'NM', 'cm', 'CH', 'sw', 
+'SW')
my @h = $templateformat =~ /(\w+)<(\w+)>/g;

for (my $ix=0; $ix + 1 < @h; $ix += 2){
    push(@names, $h[$ix +1]);
    # Match up to the next piece of template
    if($ix + 2 < @h){
    ($val, $_) = /$h[$ix](.+)($h[$ix +2].+)/ or die 'bad middle'}
    # or match to the end if there's no next piece
    else{
    ($val) = /$h[$ix](.+)/ or die 'bad end'};
    push(@values, $val)};

local($,, $\ ) = ("\t", "\n");
print(@names);
print(@values);

gives

NM      NM      CH      SW
8       8       512     no

You might want to add more robust error-checking. I could have shoved the push into @values inside the if/else. I'd have saved creating the $val variable but I'd have duplicated the push.

• 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).
