i try to divide 2 variables in order to get a percentage--that's why i'm not interested in integer division--but nothing seems to work
I think awk is suitable for this but i'm not quite sure how to use it..
any ideas?
here's what I want to do:
percentage = varA/varB

html::rewriteattributes::links
HTML::RewriteAttributes::Links(3pm) User Contributed Perl Documentation HTML::RewriteAttributes::Links(3pm)
NAME
HTML::RewriteAttributes::Links - concise link rewriting
SYNOPSIS
# up for some HTML::ResolveLink?
$html = HTML::RewriteAttributes::Links->rewrite($html, "http://search.cpan.org");
# or perhaps HTML::LinkExtor?
HTML::RewriteAttributes::Links->rewrite($html, sub {
my ($tag, $attr, $value) = @_;
push @links, $value;
$value;
});
DESCRIPTION
"HTML::RewriteAttributes::Links" is a special case of HTML::RewriteAttributes for rewriting links.
See HTML::ResolveLink and HTML::LinkExtor for examples of what you can do with this.
METHODS
"new"
You don't need to call "new" explicitly - it's done in "rewrite". It takes no arguments.
"rewrite" HTML, (callback|base)[, args] -> HTML
See the documentation of HTML::RewriteAttributes.
Instead of a callback, you may pass a string. This will mimic the behavior of HTML::ResolveLink -- relative links will be rewritten using
the given string as a base URL.

HTML::RewriteAttributes, HTML::Parser, HTML::ResolveLink, HTML::LinkExtor
