I Hate XML
XML. . . has the optimal syntax: it compresses perfectly is much hyped, so must be excellent is well supported in Java, so available to anyone!. . . and Perl support? is used everywhere (help!)
XML. . . has a complicated content describing formalism, described in schema's is easily extensible XML its noting more than Yet Another Syntax!!!! with an optional formalism
Need XML Validating translation HASH Schema / WSDL file validating complete simple fast
Need HASH Validating translation XML Schema / WSDL file validating complete simple fast
Many (unmaintained) XML modules Translate HASH to XML (and/or back) by None complete, usually slow: they just DWIM
Examples simple. Type <answer>42</answer> answer => 42
Examples complex. Type and complex. Type/complex. Content <zoo name=”Burgers Zoo”> <location>Arnhem</location> <animal>monkey</animal> <animal>donkey</animal> </zoo> zoo => { name => 'Burgers Zoo' , location => 'Arnhem' , animal => [ 'monkey', 'donkey' ] };
Examples complex. Type/simple. Content <price currency=”euro”>300</price> price => { currency => 'euro' , _ => 300 };
Why another? No run-time xpath searches: need for speed! int should not become 1. 9999, but long 2 Integer is Big. Int; must support minimal 18 digits - 121 21 363462 32461532 1 support for list, union, subtitution. Group Real qualified/unqualified name-space support
Examples create a reader; XML to HASH my $rules = XML: : Compile: : Schema->new($xml_string); my $read = $rules->compile(READER => 'mytype'); my $hash = $read->($xml); create a writer; HASH to XML my $doc = XML: : Lib. XML: : Document->new('1. 0', 'UTF-8'); my $write = $rules->compile(WRITER => 'mytype'); my $xml = $write->($doc, $hash); based on XML: : Lib. XML
Complete? No, but. . . many optimizations are implemented needs real-life testing W 3 C TRs are unreadable only newest schema spec, prepared to extend.

I Love YAML (Syck, SOX, SLi. P)
What is the expected structure? Is it documented? Can it be checked?
XML to YAML XML HASH Schema YAML
YAML validation XML HASH Schema YAML
YAML schema's XML HASH XML Schema YAML HASH YAML
I Hate XML I Love YAML
I Hate XML It's just syntax!!! I Love YAML !
It's just syntax!!! ! The real problem is: design the data-structure in a way that it can last for a very long time AND DOCUMENT THAT
