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());
}
}
