[App::scrape] does support RDF.
No, it does not. Accepting XML does not count as supporting RDF. In general, RDF cannot be effectively processed with XML tools.
Web::Magic won't help me "fake" a proper ua_string like WWW::Mechanize , and it has all those exceptions, but no cookie jar?
Web::Magic lets you specify any user agent string you like. The POD for the "set_request_header" method shows two examples of how to do precisely that:
$magic->set_request_header('User-Agent', 'MyBot/0.1');
$magic->User_Agent('MyBot/0.1'); # same as above
And if you have a cookie jar you'd like to use:
$magic->user_agent->cookie_jar($cookies);
HTML::Query, Web::Query, Web::Scraper, Web::Magic ... a lot of the same kind of work, which horse to choose?
Sell me a horse?
Selecting stuff via CSS selectors is only a very small part of what Web::Magic does. (I almost regret using that feature in my first example.) Web::Magic aims to be the swiss army knife of HTTP-addressable resources. Whether it's a classic web page, a RESTful API, an Atom feed, or a WebDAV fileshare, Web::Magic can probably make dealing with it easier.
Let's suppose you have a RESTful API which supports up XML and JSON, depending on the request's HTTP Accept header. Web::Magic notices how you're trying to access the data, and does what you mean...
Web::Magic->new('http://example.com/new-document')
->POST($xmldom)
->{entry}{id};
It's smart enough to figure out the HTTP headers you want:
POST /new-document HTTP/1.1
Host: example.com
Content-Type: application/xml
Accept: application/json, text/x-yaml
<xmldoc>...</xmldoc>
But if you'd called it like this:
my @entries =
Web::Magic->new('http://example.com/new-document')
->POST({ title => "Hello", foo => 1 })
->entries;
print $entries[0]->id;
Then the request would be more like:
POST /new-document HTTP/1.1
Host: example.com
Content-Type: application/x-www-form-urlencoded
Accept: application/atom+xml, application/rss+xml
title=Hello&foo=1
