Subject: REXML: parsing a string with unescaped ampersand entities

Hi,

REXML seems to SOMETIMES choke on parsing ampersands within entities,
e.g.

string = '<?xml version="1.0"
encoding="UTF-8"?><hello>hello&world</hello>'
doc = Document.new(string)
puts "#{doc}"

works fine (output below):
<?xml version='1.0' encoding='UTF-8'?><hello>hello&world</hello>

BUT:

string = '<?xml version="1.0" encoding="UTF-8"?><hello>hello&
world</hello>'
doc = Document.new(string)
puts "#{doc}"

crashes out with:

REXML::ParseException: #<RuntimeError: Illegal character '&' in raw
string "hello& world">
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rexml/text.rb:91:in

/Users/frankreiff/Live Developments/ruby/analyze/xml_parser.rb:102 ...
Illegal character '&' in raw string "hello& world" Line: Position: Last
80 unconsumed characters: </hello>

The difference is the space after the &

What is going on? and how can I fix this?

Best regards,

Frank
