XPath axis, get all following nodes until

Question

I have the following example of HTML:

Foo bar
lorem
ipsum
etc         


        

Answer 1

XPath 2.0 has the operator << (with $node1 << $node2 being true if $node1 precedes $node2) so that way you can use //h2[. = 'Foo bar']/following-sibling::p[. << //h2[. = 'Bar baz']]. I don't know however what nokogiri is respectively whether it supports XPath 2.0.
