But I am not comfortable with some notation used here,so thought if
anyone out there help me to redirect to a resource where I can learn
such techniques.
You need to read up on css selectors
My hard confusion is with the below lines:
***** “#ires ol li” *****
when to write this way?
what
#
stands for? Looking at the source page I sawires
is oneid. – when I need to use such
#
and when.
?
#foo finds an element with id foo whereas .foo finds an element with class foo. Which one to use depends on the markup.
- Is there any other operators like
#
and.
when using css?
Yes, there are a whole bunch, such as the pseudo selectors (:not, :nth-child), attribute selectors etc.
has fairly exhaustive info

I am searching for a good example for the below method:
Nokogiri::XML::Node#matches? (File: README — Documentation for nokogiri (1.13.8)) Nokogiri::XML::Node#fragment (File: README — Documentation for nokogiri (1.13.8))
Any one out there,ever used these 2 methods. I need an example against each,so your help will be much appreciated.
Thanks
