NAME¶
HTML::RewriteAttributes - concise attribute rewriting
SYNOPSIS¶
$html = HTML::RewriteAttributes->rewrite($html, sub {
my ($tag, $attr, $value) = @_;
# delete any attribute that mentions..
return if $value =~ /COBOL/i;
$value =~ s/\brocks\b/rules/g;
return $value;
});
# writing some HTML email I see..
$html = HTML::RewriteAttributes::Resources->rewrite($html, sub {
my $uri = shift;
my $content = render_template($uri);
my $cid = generate_cid_from($content);
$mime->attach($cid => content);
return "cid:$cid";
});
# 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" is designed for simple yet powerful HTML
attribute rewriting.
You simply specify a callback to run for each attribute and we do the rest for
you.
This module is designed to be subclassable to make handling special cases
eaiser. See the source for methods you can override.
METHODS¶
"new"¶
You don't need to call "new" explicitly - it's done in
"rewrite". It takes no arguments.
"rewrite" HTML, callback -> HTML¶
This is the main interface of the module. You pass in some HTML and a callback,
the callback is invoked potentially many times, and you get back some similar
HTML.
The callback receives as arguments the tag name, the attribute name, and the
attribute value (though subclasses may override this --
HTML::RewriteAttributes::Resources does). Return "undef" to remove
the attribute, or any other value to set the value of the attribute.

THANKS¶
Some code was inspired by, and tests borrowed from, Miyagawa's
HTML::ResolveLink.
