Bug#42495 updatexml: Assertion failed: xpath->context, file .\item_xmlfunc.cc, line 2507
Problem:
RelativeLocationPath can appear only after a node-set expression
in the third and the fourth branches of this rule:
PathExpr :: = LocationPath
| FilterExpr
| FilterExpr '/' RelativeLocationPath
| FilterExpr '//' RelativeLocationPath
XPatch code didn't check the type of FilterExpr and crashed.
Fix:
If FilterExpr is a scalar expression
(variable reference, literal, number, scalar function call)
return error.
