Subject: libhxml Node#remove! kills each loop and extension to #<<

hi,

While using #each to loop thru the children of a Node, if I remove a
node the loop breaks on it's own.

  <root>
    <a id="a"></a>
    <b id="b"></b>
    <c id="c"></c>
  </root>

  root.each { |node|
    if XML::Node === node
      node.content = "yep"
      node.remove! if node['id'] = "b"
    end
  }

The result is

  <root>
    <a id="a">yep</a>
    <c id="c"></c>
  </root>

Would tha tbe a bug? Or something that simply can't be avoided?

Also, I found this extension to #<< to be useful:

  class XML::Node
    alias_method :append, :<<
    def <<( node )
      if Array === node
        node.each { |n| self.append n }
      else
        super
      end
    end
  end

Thanks,
T.
