[phpxmlrpc-devel] Empty lines patch

[Dougal C. <do...@gu...>]

While playing with Scott Andrew LePera's pubsub experiments[1], we ran
across a problem in the XML-RPC library. At first, we thought it was
caused by Scott including a <!-- comment --> in his XML response, but I
finally tracked down the real source of the problem, which was extra
whitespace between the response's headers and content.

I've attached a diff file to work around this problem. I made two minor
changes. First, it uses preg_split() instead of just split(), in order
to catch the possibility of lines ending in just '\n' instead of '\r\n'.
This is in order to follow the tenet of "be generous in what you
receive, strict in what you send". Next, it checks for any empty
elements at the beginning of the $ar before joining them into the $data
array, because otherwise, the call to xml_parse will choke.
