Re^4: XML::Simple parsing into a hash wierd behaviour

I do not use XML::Simple myself, now that I've written XML::Rules, but it worked fine for me. Most probably because I was working within the limits of what it was designed for. Of course I had to add a few ForceArrays, but it still was the easiest solution. Because I did not need no namespaces, I did not intend to work with document oriented XML, I did not have to handle any optional attributes, ...

Query mechanisms have two problems ... it's yet another language to learn and debug and it's slow. Compared to navigating a trimmed down data structure, navigating a generic maze of objects must be slow. Of course if you need to navigate far over a complicated path, then the query mechanisms may very well be easier. They probably will. If on the other hand you need to process pretty much everything, your query mechanisms will not help you much. The ->nodeValue()s and ->getAttribute()s all over the place will hurt though.

Query mechanisms have two problems ... it's yet another language to learn I'd rather learn `Persons/Person` [download] then learning to do `GroupTags => { Persons => 'Person' }, ForceArray => [qw( Person )], my @persons = $parent->{Persons} ? @{ $parent->{Persons} } : ();` [download] and it's slow. That's not the case. XML::Simple is still far slower. The ->nodeValue()s and ->getAttribute()s all over the place will hurt though. I have no problem with a little more wordiness in a series of cut and paste lines if all trickiness goes away in exchange.	[reply] [d/l] [select]

I'd rather learn

Persons/Person
[download]

GroupTags  => { Persons => 'Person' },
ForceArray => [qw( Person )],

my @persons = $parent->{Persons} ? @{ $parent->{Persons} } : ();
[download]

and it's slow.

That's not the case. XML::Simple is still *far* slower.

The ->nodeValue()s and ->getAttribute()s all over the place will hurt though.
