Parent: | Object |
Nokogiri::XML::Reader parses an XML document similar to the way a cursor would move. The Reader is given an XML document, and yields nodes to an each block.
Here is an example of usage:
reader = Nokogiri::XML::Reader(<<-eoxml) <x xmlns:tenderlove='http://tenderlovemaking.com/'> <tenderlove:foo awesome='true'>snuggles!</tenderlove:foo> </x> eoxml reader.each do |node| # node is an instance of Nokogiri::XML::Reader puts node.name end
Note that Nokogiri::XML::Reader#each can only be called once!! Once the cursor moves through the entire document, you must parse the document again. So make sure that you capture any information you need during the first iteration.
The Reader parser is good for when you need the speed of a SAX parser, but do not want to write a Document handler.
