includes the following example:
doc = Document.new ‘sean’
doc.root.each {|e|p e} #-> Yields b, c, d, b, c, d elements
doc.root.each(‘b’) {|e|p e} #-> Yields b, b elements
However when I run it I get the results below.
Am I doing something wrong? If not, is the documentation or the code
correct? Should I be reporting this somewhere?
(My underlying goal is to find an iterator that yields one element at a
time from an XPath search, rather than doing the whole search to return
a complete array of elements.)
