As of now, a regex with the HttpMonitor or maybe the PageSequenceMonitor is probably your best bet. Admittedly it's pretty awful. Ultimately I'd like to have a poller monitor that implements a subset of the XmlCollector's functionality, and is configured in an equivalent way. That way you'd be able to use an XPath expression to describe your expectations for the document. The XmlCollector can also handle JSON documents if you configure an alternate handler, which would be nice in the poller too. We periodically kick around the idea of re-architecting the poller and collector class hierarchies to enable better code reuse, but that's a very big and disruptive project. If you feel like having a swing at writing an XmlMonitor, you'll find able assistance on this list and on the "OpenNMS Development" channel of https://chat.opennms.com/. -jeff
