Nokogiri id attribute not functioning

Rails
1

I’m building an app in rails using Nokogiri … I used *puts
documents.css("._Ak cite").length and I get the exact length I want but
when I tried the id part of the of this puts documents.css(“div#mbEnd >
cite”).length *I didn’t get the exact, makes 0 length.

I don’t know why nokogiri not recognizing the tag.

Sounds like it just doesn’t match your document but without seeing an
excerpt there’s not much more that can be said.

I really don’t why I can’t get the data if I used id because when I
tried
the class it will gives the exact data. Is there any ways that can I
used
id to fetch the data?

Per Selectors | jQuery API Documentation

Child Selector (“parent > child”)

Selects all direct child elements specified by “child” of elements
specified by “parent”.

Double check how you are referencing the parent and the children

I grabbed this code from Child Selector (“parent > child”) | jQuery API Documentation,
modified
it and it works. Just remember that multiple elements can have the same
css class, but each element must have a

distinct css id.

<!doctype html>

child demo body { font-size: 14px; }
  • Item 1
  • Item 2
    • Nested item 1
    • Nested item 2
    • Nested item 3
  • Item 3
  • Item 1
  • Item 2
    • Nested item 1
    • Nested item 2
    • Nested item 3
  • Item 3

Hope this helps.
