def xp_and(first, second)
  return "(#{first} and #{second})"
end

#xp_contains(node, needle, separator = ' ') ⇒ Object

Return an xpath contains clause for e.g. checking wether an element’s class attribute node contains a string. The optional third parameter determines how substrings are separated in the attribute node; the default is space for matching class names. Note that enclosing [ and ] are not included in the return value; this lets you more easily use and()/or()/not() operators.
