Find tag with id including [] with Nokogiri

Question

I have an html element like:

I want to search for this element by id, but it seems that nokogiri is getting confus

Answer 1

you can also do it this way

el = doc.xpath("id(spam[500])").first

for elements having id's you can call them directly through id because its always unique.

for finding out xpaths, please add a 'xpath checker' plugin to firefox. It helps a lot and very easy
