libvirt users - Mar 2010 - Problem attaching device

I keep getting an error when I try to attach a device in the libvirt api through
python

The python code is:

     conn=libvirt.open('qemu:///system')
     dom = conn.lookupByName("fedoratest")
     if dom.info()[0]==1:
         dom.attachDevice('net.xml')

And I keep getting: "libvirtError: XML description not well formed or
invalid

   The xml is a simple network card that works fine in virsh. It is just:
#cat net.xml
<interface type='network'>
           <mac address='52:54:00:00:fe:5c'/>
           <source network-'default'/>
            target dev='vnet1'/>
</interface>

I've tired giving it the full path still no luck.
Thanks in advance,

Your XML is really not well formed. This

   <source network-'default'/>

should be

   <source network='default'/>
> ? ? ? ? ? ?target dev='vnet1'/>
And you miss a < before the word target:

   target dev='vnet1'/>

should be

   <target dev='vnet1'/>

Thanks, but problem still persists. I actually fat fingered entering it the
first time???

The xmlfile really is: 

<?xml version="1.0"?>
<interface type="network">
? <mac address="52:54:00:5c:fe:a8"/>
? <source network="default"/>
? <target dev="vnet1"/>
</interface>

 I ran xmllint and it just says no DTD specified, however this works perfectly
if i use the attach-device command in virsh. I tired it both with and without
the first line version=1.0

I try running it through python and boom,?is there something else I'm
missing?? I can't find any documentation about the overall libvirt xml
schema.
Thanks again,
Steve
