I am getting error " XML parsing error: "Not well-formed (invalid token)" at Line 1 at column 1"

Just the exception without any more information isn't enough to help you. There are hundreds of reasons you could get this error, starting with your server sending non-xml as a response.

I am also getting this error when connecting to a local openfire server, but it seems to be because openfire is returning a hex-looking string at some point, and the parsing fails. This is likely more of an openfire issue, but I can't seem to find any help on this topic, so I'm turning here in hopes that someone may have some clue as to what's going on.

Here is the string it fails to parse:

"\x15\x03\x01\x00\x02\x02P"

Edit: I thought I was getting more than one response, but the first was my request going through the parser.

What is going on here? Why is it returning hexidecimals instead of xml? Does this have something to do with SSL?

@DMeganoski seems it looks like problem with ssl connection.
For example in my situation:
I tried to connect to host by local hostname, but my openfire has normal hostname and configured to use it, and has certificate for it.

I fixed my problem to provide context options to socket:

$context_options = [
                'ssl' => [
                    'peer_name'         => 'example.com',
                ],
            ];

So if I use local hostname in $address, socket will check sertificate for 'example.com'.

But it's not all. Next broken autorization, because xmpp use host from $address. But in 'Options' object we also can fix it bu call $Options->setTo() method.

I don't know your case, but may be you has wrong certificate or something also. You can try to switch off sertificate checking: ['ssl' => ['verify_peer' => false,'verify_peer_name' => false]]

Or allow self-signed sertificate: ['ssl' => [allow_self_signed' => true]]
Or both.

To do it you can use stream_context_set_default method or vote for #31 pull request to add context options in xmpp project.
