I extended the Nokogiri::HTML:Document class as follows to add a function called on_same_line?
module Nokogiri
module HTML
class Document
def on_same_line?(node1,node2,font_sizes)
return false if node1.nil? or node2.nil? or font_sizes.nil?
return false if (node1.name != "div" || node2.name != "div")
fsize1 = font_sizes[node1.children[0].children[0].attributes["class"].value]
fsize2 = font_sizes[node2.children[0].children[0].attributes["class"].value]
style1 = node1.attributes["style"].value
style2 = node2.attributes["style"].value
top1 = style1.split(/;/)[1].split(/:/)[1].to_i
top2 = style2.split(/;/)[1].split(/:/)[1].to_i
(top1 + fsize1 - top2 - fsize2).abs < 4
end
end
end
end
I placed this code in a file located at lib/nokogiri/html/document.rb in my rails 3 application tree
I call this function as follows
if @html_doc.on_same_line?(node,node2,font_size_hash)
### do something
end
This code is in a separate custom ruby class that I created. This class is MyClass and is in MyModule. The code for this class is placed under lib/my_module/my_class.rb
Now when this code is executed as part of my rails application, I get the following error.
unexpected '?' after '[#<Nokogiri::CSS::Node:0x00000100dfebd8 @type=:ELEMENT_NAME, @value=["on_same_line"]>]'
I have no idea why this is happening. Could someone please help me
Also when I run this same code outside the rails app, I dont get any errors, and it works as expected
Thanks Paul
