Re: Why Would HTML::LinkExtor return a hash of attributes?

"what prompted the author to return the results as an array with a hash as the second item? "

Where do you get that from?

"It's kind of confusing me. For a start, if it's a hash, shouldn't that be ..."

It's not a hash, where do you get hash from?

And why is print "$tag @{[%links]}\n"; scary to you?

More than anything it's kind of silly to me, cause all that sub needs to be is print "@_\n";

update:
"And more to the point, I'm racking my not-inconsiderable knowledge of HTML to try and find a situation where a single tag could have two or more attributes which were links.".

AFAIK, no attributes are ever "links". Duplicate SRC attributes wouldn't be valid HTML, and one of the 2 would be ignored. It's like this, if anyone writing HTML wants anybody to somewhat accurately interpret it, well, he's gotta write valid HTML, right? (right)

Isn't it a hash? Why does it have "key => val, key => val" if it isn't? Plus, if it isn't, why does the sub grab it as: `my($tag, %links) = @_;` [download] if it isn't a hash? `all that sub needs to be is print "@_\n"` Try it. You get both the "HREF" and the thing it's a link to. I don't want to extract "HREF" 5,000 times do I? -- `($_='jjjuuusssttt annootthheer pppeeerrrlll haaaccckkeer')=~y/a-z//s;print;` [download]	[reply] [d/l] [select]

`=>` Is a fancy comma (,). It allows you to say `print I => AM => NOT => QUOTING => WORDS => TIMES => 5;` [download] which would print `IAMNOTQUOTINGWORDSTIMES5` Using this fancy comma doesn't make a hash. A hash is a "data structure", and `I => AM => NOT => QUOTING => WORDS => TIMES => 5` is a list. Now you can do many things with lists. You can create arrays ( also data structures ) `my @ARRAY = ( I => AM => NOT => QUOTING => WORDS => TIMES => 5 );` [download] and you can create hashes `my %HASH = ( I => AM => NOT => QUOTING => WORDS => TIMES => 5 );` [download] . Do you follow now? `____________________________________________________` ** The Third rule of perl club is a statement of fact: pod is sexy.	[reply] [d/l] [select]
