Question

i’m trying to learn regex parse in javascript.

I need to read the text in a “span”

<span class="item_color_title">Status:</span>
<span class="item_color_success">
Alive
</span>

“Alive” is what i need. Any easy way out?

This is for a firefox extension, where i’ve:

var req = new XMLHttpRequest();  
req.open('GET', 'http://www.example.com/', false);   
req.send(null);  
if(req.status == 200)  
    standard_status.label = req.responseText;

And, standard_status should say “Alive”

Thanks!!

Answer 1

Well, if you really want to use a regexp you could use this:

var text   = req.responseText.replace('\n', '')
  , status = text.match(/<span class="item_color_success">(.*)<\/span>/)[1]

standard_status.label = status

You need to replace the linebreaks as js is not correctly matching linebreaks with .* in combination with /.*/m.

Hope that helps.
