Re: [Vala] The name `type' does not exist in the context of `Xml.XPath.Object*'

[Joseph Montanez <jmontanez gorilla3d com>]

I was able to resolve it I had a complete brain fart on the fact
libxml is not gobject. So I switched the "var" to "unowned" and the
datatype.

                // Search for Posts
                Xml.XPath.order_doc_elements (doc);
                var xpath = new Xml.XPath.Context(doc);
                unowned Xml.XPath.Object results = xpath.eval("//content");

                // Go through results
                if (results != null && results.type == Xml.XPath.ObjectType.NODESET) {
                        unowned Xml.XPath.NodeSet nodes = result.nodesetval;
                        printerr ("got %d nodes\n", nodes.length());
                        for (int i = 0; i < nodes.length(); i++) {
                                unowned Xml.Node node = nodes.item(i);
                                printerr ("  -> %s\n", node.get_path());
                        }
                }
