Declaring XML

How many times have you built XML by hand?

Entry = Struct.new(:name, :email)
me = Entry.new("Jim", "jim@fakemail.com")

out = ''
out << "<entry><name>" << me.name  <<
  "</name><email>"     << me.email <<
  "</email><entry>"

puts out

Producing…

<entry><name>Jim</name><email>jim@fakemail.com</email><entry>
