scrapy - How do I select attributes with colons in them with XPath -


i want xmlns:fb attribute from: 

<html xmlns:fb="http://www.facebook.com/2008/fbml"></html>

it doesn't work if use: 

hxs.select('//html/@xmlns:fb')

you may use //html/namespace::fb instead of //html/@xmlns:fb uri 'http://www.facebook.com/2008/fbml'
