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

Translate HASH to XML (and/or back) by

None complete, usually slow: they just DWIM

Examples

simpleType

<answer>42</answer>

answer => 42

Examples

complexType and complexType/complexContent

<zoo name=”Burgers Zoo”> <location>Arnhem</location> <animal>monkey</animal> <animal>donkey</animal></zoo>

zoo => { name => 'Burgers Zoo' , location => 'Arnhem' , animal => [ 'monkey', 'donkey' ] };

Examples

complexType/simpleContent

<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 long 2

Integer is BigInt; must support minimal 18 digits- 121 21 363462 32461532 1

support for list, union, subtitutionGroup

Real qualified/unqualified name-space support

Examples

my $rules = XML::Compile::Schema->new($xml_string);my $read = $rules->compile(READER => 'mytype');my $hash = $read->($xml);

my $doc = XML::LibXML::Document->new('1.0', 'UTF-8');my $write = $rules->compile(WRITER => 'mytype');my $xml = $write->($doc, $hash);

create a reader; XML to HASH

create a writer; HASH to XML

based on XML::LibXML

Complete?

No, but...

many optimizations are implemented

needs real-life testing

W3C TRs are unreadable

only newest schema spec, prepared to extend.

Future

WSDL

SOAP

CPAN6

I Love YAML(Syck, SOX, SLiP)

What is the expected structure?

Is it documented?

Can it be checked?

It's just syntax!!!!

It's just syntax!!!!

The real problem is:design the data-structure in a waythat it can last for a very long time

AND DOCUMENT THAT
