Nokogiri::XML::SAX::Parser
class Nokogiri::XML::SAX::Parser
This parser is a SAX style parser that reads it's input as it deems necessary. The parser takes a Nokogiri::XML::SAX::Document, an optional encoding, then given an XML input, sends messages to the Nokogiri::XML::SAX::Document.
Here is an example of using this parser:
# Create a subclass of Nokogiri::XML::SAX::Document and implement # the events we care about: class MyDoc < Nokogiri::XML::SAX::Document def start_element name, attrs = [] puts "starting: #{name}" end def end_element name puts "ending: #{name}" end end # Create our parser parser = Nokogiri::XML::SAX::Parser.new(MyDoc.new) # Send some XML to the parser parser.parse(File.open(ARGV[0]))
For more information about SAX parsers, see Nokogiri::XML::SAX. Also see Nokogiri::XML::SAX::Document for the available events.

Public Class Methods
Create a new Parser with doc
and encoding
# File lib/nokogiri/xml/sax/parser.rb, line 70 def initialize doc = Nokogiri::XML::SAX::Document.new, encoding = 'UTF-8' check_encoding(encoding) @encoding = encoding @document = doc @warned = false end
Public Instance Methods
Parse given thing
which may be a string containing xml, or an IO object.
# File lib/nokogiri/xml/sax/parser.rb, line 80 def parse thing, &block if thing.respond_to?(:read) && thing.respond_to?(:close) parse_io(thing, &block) else parse_memory(thing, &block) end end
Parse a file with filename
# File lib/nokogiri/xml/sax/parser.rb, line 100 def parse_file filename raise ArgumentError unless filename raise Errno::ENOENT unless File.exist?(filename) raise Errno::EISDIR if File.directory?(filename) ctx = ParserContext.file filename yield ctx if block_given? ctx.parse_with self end
Parse given io
# File lib/nokogiri/xml/sax/parser.rb, line 90 def parse_io io, encoding = 'ASCII' check_encoding(encoding) @encoding = encoding ctx = ParserContext.io(io, ENCODINGS[encoding]) yield ctx if block_given? ctx.parse_with self end
# File lib/nokogiri/xml/sax/parser.rb, line 109 def parse_memory data ctx = ParserContext.memory data yield ctx if block_given? ctx.parse_with self end
