erlang or ADA -- create web Scraping - parse information from couple website and generate in html

Question

I must do some web for my elrang or ada project. 1)I must write: download concurrent data from three portals associated with weather --> It is a main problem. I don't know how to download such data. Maybe some parser ? I found some information about erlang parser but there are not enough to understand to me. May can be some parser for ada?

What exactly want to do: I have got some web with html structure:

<div class="info">
        <span class="cond">Mostly clear and colder</span>
        <span class="low" style="color:#ffffff;">Lo </span><strong class="temp">-12<span>°</span></strong>
        </div>

And want to extract information: "-12". Is any possible to do it?

After extracted this informations must update my database Finally create some graph which illustrates all parsed informations.

Any hint will be very appreciated.

There isn't a library like Python's Beautiful Soup or Ruby's Nokogiri for Erlang. I think your best bet is to use Beautiful Soup or Nokogiri and then write some code to transfer the relevant information from Python/Ruby to Erlang via the BERT-RPC protocol.

I also did some searching and came across this: http://erlang.org/pipermail/erlang-questions/2010-January/049023.html Hope this helps!
