in thread XML:: Twig - can you check for text following the element being handled?

I think this is working as designed, la handler is called before its parent snot , before siblings are parsed and added to parent, so naturally next_sibling_text returns empty string until the parent snot handler is called

So the best and simples solution is to do this testing in a handler for the parent

#!/usr/bin/perl -- use strict; use warnings; use XML::Twig; my $xml = <<'__XML__'; <?xml version="1.0" encoding="UTF-8"?> <root> <snot>the <la>snot</la> balls are made of snot </snot> <snot>the <la>snot</la> bells are made of snot </snot> <snot>the <la>snot</la> bowls are made of snot </snot> </root> __XML__ #~ Handlers are triggered in fixed order, sorted by their type #~ (xpath expressions first, then regexps, then level), then by #~ whether they specify a full path (starting at the root element) #~ or not, then by by number of steps in the expression , then #~ number of predicates, then number of tests in predicates. #~ Handlers where the last step does not specify a step #~ ("foo/bar/*") are triggered after other XPath handlers. Finally #~ "_all_" handlers are triggered last. { my @snot; my $t = XML::Twig->new( twig_handlers => { 'snot' => sub { warn $_->path, "\n"; push @snot, $_->text; return !!1; }, ## la , triggered before snot 'la' => sub { warn $_->path, "\n"; push @snot, [ $_->text , ## doesn't contain next_sibling_text because not parsed yet, as expect +ed $_->parent->text , ]; return !!1; }, }, ); $t->parse($xml); undef $t; use Data::Dumper(); print Data::Dumper->new([ \@snot ])->Indent(1)->Dump; } __END__ /root/snot/la /root/snot /root/snot/la /root/snot /root/snot/la /root/snot $VAR1 = [ [ 'snot', 'the snot' ], 'the snot balls are made of snot ', [ 'snot', 'the snot' ], 'the snot bells are made of snot ', [ 'snot', 'the snot' ], 'the snot bowls are made of snot ' ];
