Well, its easy enough: if node1.to_s == node2.to_s Or if node1.content == node2.content to_s is like outerHTML and content is innerHTML (sort of). But is that
good for Ruby too? I wonder how changing #== to identity might effectcurrent users?
Best guess it gives them a nice performance boost, since I'm not seeing how comparing on content is useful
Even so, I agree that comparing raw xml strings doesn't
makes sense, but comparing equivalence, as opposed to identity, can be useful, ie. same tag names, same attributes (irregardless of order)and same data.
See above. Otherwise it would seem like we are suggesting that XML
nodes should be immutable.
Hmm, why do you say that? Charlie
