Summary: Stringing commands bypasses correct node creation
Initial Comment:
When I create something along the lines of:
foo << XML::Node.new('bar') << "bars contents"
The following is returned:
---------
<foo>
<bar/>bars contents
</foo>
---------
However, this:
foo << bar = XML::Node.new('bar')
bar << "bars contents"
returns this:
---------
<foo>
<bar>bars contents</bar>
</foo>
---------
These results have been sporadic at times, it seems. When I create
XML::Documents in the console, sometimes it works fine, sometimes it doesn't.
I have been unable to pinpoint a specific cause, but I am, however, having to
rewrite a good bit of my code because invalid XML is being produced due to this
bug.

Hello,
Sorry to interrupt, but I am against this change.
Operator << in Ruby generally returns self, not the
appended object.
Actually, Node#<< used to return the appended object but
it was changed to be consistent with the Ruby standard
at one point.

Hi Eric,
The problem is that << returns self, and not the appended child. I've changed
this in trunk, so the next version of libxml should work the way you request.

This also applies to the node creation as well, as can be seen here:
>> a = XML::Document.new()
=> <?xml version="1.0"?>
>> a.root = XML::Node.new('foo')
=> <foo/>
>> root = a.root
=> <foo/>
>> root << XML::Node.new('bar') << XML::Node.new('baz')
=> <foo>
<bar/>
<baz/>
</foo>
>> a = XML::Document.new()
=> <?xml version="1.0"?>
>> a.root = XML::Node.new('foo')
=> <foo/>
>> root = a.root
=> <foo/>
>> root << bar = XML::Node.new('bar')
=> <foo>
<bar/>
</foo>
>> bar << XML::Node.new('baz')
=> <bar>
<baz/>
</bar>
>> a
=> <?xml version="1.0"?>
<foo>
<bar>
<baz/>
</bar>
</foo>
>>
