How does the above work
m Match
{ inside these braces (as the delimiter?)
id=" the characters id="
( Start the capture for $id
[^"] The list of characters beginning with "
But wasn't that done on line 3 where we
looked for a "

) end of capture for $id
" the end " for the data element captured
.* anything until
name=" etc do it all again till

Good exercise!
The answer is short, but since you already did this effort I'll tell
you a way to figure out what's missing that's very close to your
approach: Ask japhy's YAPE::Regex::Explain about it:
use YAPE::Regex::Explain;
print YAPE::Regex::Explain->new(qr{id="([^"]*)".*name="([^"]*)"/
>})->explain;
