您可以使用带ruby nokogiri的通配符搜索html属性吗

Question

I know you can search text in html using wildcards. Can you search for attribute values in html using wildcards with nokogiri

eg, suppose I want to search for classes with value *session*

Answer 1

You can use xpath contains() function to search the document. Something like:

doc.xpath("//*[@*[contains(., 'session')]]").each do |ele|
  # something
end

This search returns all the elements with any attribute whose value contains the string 'session'.

Answer 2

几天前发生了类似的问题-请注意类值周围的空格。

find(:xpath, "//*[contains(concat(' ', normalize-space(@class), ' '), ' icon-edit ')]")
