So:
some_node = doc.find('/foo')
child = some_node.children
while child
... do stuff
child = child.next
end
There is also a bit of ruby syntactic sugar that defines an each method,
so you can do:
some_node = doc.find('/foo')
some_node.children.each do |node|
... do stuff
end
Thus node.children is a XML::Node that acts both as a single node and
also a collection. The same is true for attributes.
For anyone who works with the DOM's built into browsers, or follows the W3C standards (\http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/core.html), this is a bit weird and non-intuitive.
I'd prefer that node.children becomes node.first and node.children returns an array of child nodes. We'd then add an each_child method to XML::Node (based on node.first and node.next) for quick and easy iteration.
some_node = doc.find('/foo')
child_nodes = some_node.children
child_nodes.class == "Array"
some_node.each_child do |node|
... do stuff
end
And for attributes, I vote that libxml copies REXML's interface:

Thoughts?
