Re: SimpleXMLIterator methods

I finally found the answer to my own question (although re-reading, I see I
have the hierarchy wrong, which is why it didn't work as I expected).

If you want to treat a simplexml object as an iterator, then you have to
call simplexml_load_[file|string] with an (as yet) undocumented second
parameter: 'SimpleXMLIterator'

e.g. $sxi = simplexml_load_file('mydata.xml', 'SimpleXMLIterator');

I found this in the ext/spl/tests/sxe_003.phpt file.

P.S. Is there anyway to get PHPDoc/JavaDoc style API documentation out of
the ext/xxx classes? (rather than my somewhat dodgy attempts to understand
the source:)
