nokogiri - Why is this generated ruby regex not working in the actual code? -

-

i found site can generate ruby regex. enter text , click part want extract:

enter image description here

so tried it:

product.css('.cravgstars .swsprite span').text[/([+-]?\\d*\\.\\d+)(?![-+0-9\\.])/, 1]

to 4.4 got nil instead.

is regex not working or placed in incorrect way?

try this:

s = "4.4 out of 5 stars" p s[/([+-]?\d*\.\d+)(?![-+0-9\.])/] # >> "4.4"

you can find wayregexp.new:

regexp.new('([+-]?\\d*\\.\\d+)(?![-+0-9\\.])') # => /([+-]?\d*\.\d+)(?![-+0-9\.])/
