| Subject: | Same tag name in different locations causes spurious change |
Attached below are two variations of the same XML file. Both have
<Description> tags at the root level and also one level deeper, inside
the <TimeZone> tag. They should be considered identical, but this short
example program erroneously reports that they are different.
use XML::SemanticDiff;
my $diff = XML::SemanticDiff->new();
foreach my $change ($diff->compare('derived.xml', 'orig.xml')) {
print "$change->{message}\n";
}
% perl compare.pl
Child element 'Description' missing from element
'/LocalPresentationManifest[1]/Properties[1]/TimeZone[1]'.
Rogue element 'Description' in element
'/LocalPresentationManifest[1]/Properties[1]/TimeZone[1]'.
