Nokogiri how to get the parent text and not the childs text and reference the text back to its parent
Let's say I have this sample:
page = "<html><body><h1 class='foo'></h1><p class='foo'>hello people<a href='http://'>hello world</a></p></body></html>"
@nodes = []
Nokogiri::HTML(page).traverse do |n|
if n[:class] == "foo"
@nodes << {:name => n.name, :xpath => n.path, :text => n.text }
end
end
the results would for the n.text would b开发者_开发知识库e hello peoplehello world, I want to do it in a way so I can get the parent text and its childs text, but relate them to their tag
so the result would be something like
@nodes[0][:text]=""
@node[1][:text]= [{:Elementtext1 => "hello people", :ElementObject1 => elementObject},{:Elementtext2 => "hello world", :ElementObject2 => elementObject}]
There we go
require 'rubygems'
require 'nokogiri'
doc = Nokogiri::HTML(DATA.read)
nodes = doc.root.css('.foo').collect do |n|
{ :name => n.name,
:xpath => n.path,
:text => n.xpath('.//text()').collect{|t|
{ :parent => t.parent.name,
:text => t.text }}}
end
p nodes
__END__
<html>
<body>
<h1 class='foo'></h1>
<p class='foo'>hello people<a href='http://'>hello world</a></p>
</body>
</html>
you cannot reach all elements using traverse since it visits only the direct children of the root. Hence, I use a css selector to get all elements with class foo. And then, for each found element, I use an xpath selector to get all text nodes below it.
