Hi
I was wondering about the best way to get the structure of a list of matches.
i.e. /($re1)($re2)/g produces a list of paired matches but when processing with map or grep you need a counter to know which item you got
grep { } $str=~/($re1)($re2)/g
Thats not very scalable...
Does anybody know a nifty way to get a list of arrays returned, like in
do {my @a; push @a, [$1,$2] while $str=~/($re1)($re2)/g; @a }
???
some code examples:
DB<16> $a=join "",0..3
DB<17> x $a=~/(.)(.)/g
0 0
1 1
2 2
3 3
DB<18> x do {my @a; push @a, [$1,$2] while $a=~/(.)(.)/g; @a }
0 ARRAY(0x8ed1a18)
0 0
1 1
1 ARRAY(0x8ed1ce8)
0 2
1 3
BTW: couldn't find an array holding the values of $1,$2,... in the perldocs !?!

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).
