Ruby 使用 xmlparser 解析 XML 信息
require 'xmlparser'class XMLRetry<Exception; end
class SampleParser<XMLParser
private
def startElement(name, attr)
if name == "person"
attr.each do |key, value|
print "Found person of type #{value}.\n"
end
end
if name == "name"
$print_cdata = true
self.defaultCurrent
else
$print_cdata = false
end
end
def endElement(name)
if name == "name"
$print_cdata = false
end
end
def character(data)
if $print_cdata
puts ("\tName is: #{data}")
end
end
end
xml = $<.read
parser = SampleParser.new
def parser.unknownEncoding(e)
raise XMLRetry, e
end
begin
parser.parse(xml)
rescue XMLRetry
newencoding = nil
e = $!.to_s
parser = SampleParser.new(newencoding)
retry
rescue XMLParserError
line = parser.line
print "Parse error(#{line}): #{$!}\n"
