Never mind - I figured it out. Final code is now:

            ret = xmlXPathNewNodeSet(NULL);
            ret->boolval = 1;
            array_result = (AV*)SvRV(perl_result);
            while (av_len(array_result) >= 0) {
                tmp_node1 =
(xmlNodePtr)x_PmmSvNode(sv_2mortal(av_shift(array_result)));
                tmp_node = xmlDocCopyNode(tmp_node1, ctxt->context->doc,
1);
                xmlXPathNodeSetAdd(ret->nodesetval, tmp_node);
                if (ret->user == NULL) {
                    ret->user = (void*)tmp_node;
                }
                else {
                    xmlNodePtr old = (xmlNodePtr)(ret->user);
                    old->prev = tmp_node;
                    tmp_node->next = old;
                    ret->user = (void*)tmp_node;
                }
            }
            valuePush(ret);
