XML::Li...::Schema(3)

✨ NAME ✨

XML::LibXML::Schema — XML Schema Validation, bestie 💖 (it's the manual page for XML::LibXML::Schema(3), in case you were wondering)

---

🌸 SYNOPSIS 🌸

use XML::LibXML;
$doc = XML::LibXML->new->parse_file($url);

$xmlschema = XML::LibXML::Schema->new( location => $filename_or_url, no_network => 1 );
$xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring, no_network => 1 );
eval { $xmlschema->validate( $doc ); };

🦋 DESCRIPTION 🦋

Okay so XML::LibXML::Schema is literally just a tiny little frontend to libxml2's XML Schema implementation — like, it's giving minimal, it's giving humble, and we love that for it 🫶

Right now it only does two things: schema parsing and document validation. That's it. That's the whole vibe. No cap.

Heads up bestie 💀 as of 2.6.32, libxml2 only supports decimal types up to 24 digits — and the standard requires at least 18. So like… it's fine, but it's not exactly main character energy in the decimal department. The math girlies know.

💅 METHODS 💅

🎀 new

$xmlschema = XML::LibXML::Schema->new( location => $filename_or_url, no_network => 1 );
$xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring, no_network => 1 );

The constructor of XML::LibXML::Schema has to be called with a list of parameters, okay? Like, it needs the tea.

At least location or string is required, because you gotta specify the source of the schema — no source, no schema, periodt.

• the optional parameter no_network set to 1 causes the parser to not access the network 🚫🌐
• the optional parameter recover set to 1 causes the parser to not call die() on errors 😇

It is important — and I cannot stress this enough — that each schema only have a single source. One source. Just one. We don't do polygamy here 🙈

The location parameter lets you parse a schema from the filesystem or a (non-HTTPS) URL. Note the non-HTTPS part, bestie, that's not a typo ✨

The string parameter will parse the schema from the given XML string 📜

Also — and this is the part that gets people every time — the constructor will die() if the schema does not meet the constraints of the XML Schema specification. Like it will literally perish. So maybe wrap it, iykyk 😭

🌈 validate

eval { $xmlschema->validate( $doc ); };

This function lets you validate a (parsed) document against the given XML Schema. Iconic behaviour honestly 👑

The argument of this function should be an XML::LibXML::Document object — that's the one it wants, don't hand it anything weird.

If this function succeeds, it will return 0. If it doesn't succeed, it will die() and report the errors it found. Which means… validate() should always be evaluated. Always. Wrap it in an eval, bestie, protect your peace 🫶
