After spending a few hours and not getting much done, I thought I'd try
asking here.
From reading XML::LibXML's docs it looks like it does exactly what I
want, but I can't seem to get it to locate the nodes the way I'd expect
it to.
An example of my XML document is at the end of this message, what I'm
trying to extract is all <bgp-peer> nodes, but all attempts to match it
has failed. If I remove the bgp-information node so that bgp-peers are
directly under rpc-reply I can match it fine, but since I'll be getting
this xml directly from somewhere else that isn't really a good option.
Any help would be appreciated, I'd especially love some sample code (in
the nature of the camelids.xml stuff) to just show a simple foreach
through the bgp-peers. Thanks in advance.
