@veridtools/dmn-parserDMN XML parser

Converts any DMN 1.1→1.5 file into a typed, normalized TypeScript model. One function call, zero platform dependencies.

Fully typed model

Every element — Decision, DecisionTable, Rule, InputClause, ItemDefinition — is a TypeScript interface. IDE autocomplete and type safety from the first import.

Normalized output

hitPolicy defaults to UNIQUE, isCollection to false, empty inputEntry to "-", CDATA and XML entities produce identical output. No surprises.

DMN 1.1 → 1.5

All five namespace variants recognized automatically. DMN 1.4+ Conditional/Filter/Iterator and DMN 1.5 typeConstraint supported out of the box.

O(1) index

Every element with an @id is registered in model.index — resolve any href in constant time without traversing the tree.

safeParse — never throws

Use parse() for direct access or safeParse() for a discriminated union result — catch malformed files gracefully without try/catch.

Single runtime dependency

Only fast-xml-parser at runtime. No platform SDKs, no network calls, works in Node, Bun, and browser (via bundler).
