Hi,
Expr::push_predicate has
die "Only 1 predicate allowed on FilterExpr in W3C XPath 1.0"
if @{$self->{predicates}};
This appears untrue, the production is
[20] FilterExpr ::= PrimaryExpr
| FilterExpr Predicate
So for e.g. $var[1][1] this is something like
FilterExpr
FilterExpr
FilterExpr
PrimaryExpr
Predicate
Predicate
regards,
