How to search an XML when parsing it using SAX in nokogiri
- by ralph
I have a simple but huge xml file like below. I want to parse it using SAX and only print out text between the title tag.
<root>
<site>some site</site>
<title>good title</title>
</root>
I have the following code:
require 'rubygems'
require 'nokogiri'
include Nokogiri
class PostCallbacks < XML::SAX::Document
def start_element(element, attributes)
if element == 'title'
puts "found title"
end
end
def characters(text)
puts text
end
end
parser = XML::SAX::Parser.new(PostCallbacks.new)
parser.parse_file("myfile.xml")
problem is that it prints text between all the tags. How can I just print text between the title tag?
