Nokogiri::XML::NodeSet #first(5) includes nils

[Andrew Derenge]

Hi, first time poster so please let me know if I should be asking this somewhere else or should be phrasing my question differently.

When using first on a NodeSet with an argument, I am receiving nils in the array. I would expect the behavior to be similar to the ruby doc enumerable description of first.

An example from ruby doc being:

%w[foo bar baz].first(10) #=> ["foo", "bar", "baz"]

What I expect:

Nokogiri::HTML('<a></a><a></a>').css('a').first(3)

[#<Nokogiri::XML::Element:0x3fc3dfd5f1c8 name="a">, #<Nokogiri::XML::Element:0x3fc3dfd5f1b4 name="a">]

What I get:

Nokogiri::HTML('<a></a><a></a>').css('a').first(3)

[#<Nokogiri::XML::Element:0x3fc3dfd5f1c8 name="a">, #<Nokogiri::XML::Element:0x3fc3dfd5f1b4 name="a">, nil]

Is this expected behavior?

Thanks for reading and any direction would be appreciated!

Hi Andrew,

Thanks for asking this question. This seems like a bug to me. Would you mind opening a github issue?
