For the record we don't support SAX's dom-node property. There is no DOM tree backing the SAX event stream. It's generated from XNI. You'd have to keep your own stack to track the context (and something else to keep track of siblings) to generate an XPath expression.
The tricky part is figuring out the context of the error. None is provided so you need to make some assumptions (this also applies to the DOM while it's being built as well) about event order and where an error is reported in the stream. This topic came up last year [1]. I still feel that generating an XPath given the current APIs cannot be done reliably, though you can probably get a good approximation for some errors (like with simple types).
