What problem is this PR intended to solve?
Avoid raising Ruby exceptions from within libxml2 error callbacks while evaluating xpath queries in
xmlXPathEvalExpression
. Instead, collect them in an array and raise an exception afterxmlXPathEvalExpression
returns.Partly addresses #1610.
I've also cleaned up xml_xpath_context.c a bit while I was in there.
Have you included adequate test coverage?
Existing test coverage is appropriate.
Does this change affect the behavior of either the C or the Java implementations?
The only behavior change is for C to match JRuby's exception type when an xpath function can't be found. The test has been updated to remove the conditional on engine.
