Absolutely, that's what tap is for.

[Mojolicious] Re: Using Mojo::DOM to update

[Stefan Adams]

Sorry, I knew I should know better.

I was using the ojo#x  example and I
just added on to it:

$ perl -Mojo -E 'say x(f("test.html")->slurp)->at("title")->content("NEW TEXT")'

I've lost access to the dom!  I needed to store the dom object in a
variable so I could get back to the dom after looping thru find:

$ perl -Mojo -E 'my $dom = x(f("test.html")->slurp);
$dom->at("title")->content("NEW TEXT"); say $dom'

There was a discussion recently about tap.  Is this a good use for tap?

$ perl -Mojo -E 'say
x(f("index.html")->slurp)->tap(sub{$_->at("title")->content("NEW
TEXT")})'

Now I have the full dom with my updated information!

[Mojolicious] Using Mojo::DOM to update

[Stefan Adams]

Can Mojo::DOM be used to update information in a tree, or is it just used
to select information?

For example, how could I remove the https?://host from all links (e.g. src,
href)?
