Research direction
Start by reproducing the Xsoup.compile("//li[last()]/p/span/a/@href") example against the reported parser error. Trace how the predicate is parsed and compare the result with the expected XPath last() behavior. Done means the expression is accepted and returns the intended href, with a regression test covering the query.
