There are many different ways to locate the element you want.
For example, if
<icon src="pngpath"/>
is relatively unique and we use it as an anchor.
Then the code would be:
#require 'nokogiri'
doc = Nokogiri::XML File.read "file.xml" #Read xml file and parse into Nokogiri object
ic = doc.css('icon[src="pngpath"]') #locate icon element
theId = ic.first.parent.get_attribute :id #Find the id
p theId
#=> "firstchannel"
Depends on different situation, you might need different approach to find the
right thing you want.

I think:
doc = Nokogiri::HTML(info_html)
channel = doc.css('channel')[0]['id']

Nokogiri doesn't check if theinfo_htmlstring is a valid HTML, he just expects HTML format, so with Yuting You XML example will work just fine. You also can try in your console.
