Subject: [ruby-talk:25045] RE:  REXML Question (Re: XML libraries (Re:  Re:	 ruby and webser vices))

Alright, I started playing with REXML last night and so far it looks pretty
good. I just have a couple quick questions. Let me start by giving you a
little quick background on how the Jabber protocol works, so that you'll
understand the question I'm about to ask.

With Jabber, you open a TCP socket to the server and then create a "stream"
document. Basically, the entire connections takes place in what is
considered to be a single document. Actually, its really two documents, one
to the server and one from the server. So, the idea is that I need to be
able to create a "stream:stream" document and be able to add document
fragments to the document on the TCP socket. This sounds more difficult than
it really is.

Basically, I need to be able to send the initial "stream:stream" element
like this:

<stream:stream to='jabber.com' xmlns='jabber:client'
xmlns:stream='http://etherx.jabber.org/streams'>

However, when I create the element with REXML it ends up being closed:

<stream:stream xmlns='jabber:client' to='jabber.com'
xmlns:stream='http://etherx.jabber.org/streams'/>

I figure I could probably work around this easily enough by writing the
output to a string and then removing the slash, but I was wondering if
somebody else had a better solution? (I could, of course, build the entire
opening element manually and not use REXML, but I'd prefer not to do this.)

Any help would be appreciated.

Ben

Go have a bash. I found it very easy to use. The XPath facilities make it
really trivial to navigate the elements.
