I'm having the same issue. It seems the issue manifest itself when
callbacks is set. Below is an example; if I remove DOCTYPE tag, the problem
is gone. Any ideas on solutions or workarounds?
class Handler
include XML::SaxParser::Callbacks
def on_start_element(element, attributes)
puts element
end
end
xp = XML::SaxParser.new
xp.callbacks = Handler.new
xp.string = <<-EOS
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Results SYSTEM "results.dtd">
<Results>
<a>a1</a>
</Results>
EOS
xp.parse
