How to Convert XML to Haskell Data Types - Step by Step Guide

Step 1

Input Your XML Schema

Start by adding your XML data that needs to be converted to Haskell data types. The tool analyzes the structure to generate appropriate Haskell modules with type safety and functional programming patterns.

Example: Try This XML Data

Copy and paste this XML example to see how it works: ⚡

<?xml version="1.0" encoding="UTF-8"?>
<academic-paper id="PAPER-2024-001" status="published">
  <metadata>
    <title>Functional Programming in Haskell: A Comprehensive Study</title>
    <abstract>This paper explores advanced functional programming concepts in Haskell</abstract>
    <publication-date>2024-03-15</publication-date>
    <doi>10.1000/haskell.2024.001</doi>
    <is-peer-reviewed>true</is-peer-reviewed>

    <volume>34</volume>
    <issue>2</issue>
    <impact-factor>2.85</impact-factor>
  </journal>
</academic-paper>
Step 2

Configure Haskell Options

Customize how your XML is converted to Haskell data types! ⚙️ Choose functional programming patterns and type safety options.

Algebraic data types: Generate data types with strong type safety and pattern matching
Aeson integration: Automatic JSON serialization with Aeson ToJSON and FromJSON instances
Maybe types: Built-in Maybe types for nullable fields following Haskell best practices
XML parsing: Integration with xml-conduit for robust XML processing
Step 3

Get Generated Haskell Code

Watch the transformation! ✨ Your XML structure becomes type-safe, functional Haskell data types.

Haskell Code Output

Your XML becomes these Haskell data types:

-- Language extensions
{-# LANGUAGE DeriveGeneric #-}
{-# LANGUAGE OverloadedStrings #-}

module AcademicPaper where

import GHC.Generics
import Data.Aeson
import Data.Text (Text)

data AcademicPaper = AcademicPaper
  { paperId :: Maybe Text
  , status :: Maybe Text
  , metadata :: Maybe Metadata
  , journal :: Maybe Journal
  } deriving (Show, Eq, Generic)

-- JSON instances
instance ToJSON AcademicPaper
instance FromJSON AcademicPaper

What is XML to Haskell Conversion? 🔄

XML to Haskell conversion transforms XML schemas into Haskell algebraic data types with strong type safety and functional programming patterns. This process analyzes XML structure and generates Haskell modules that can serialize and deserialize XML data, making it easy to work with XML in type-safe Haskell applications.

The generated Haskell data types include Maybe types for nullable fields, automatic Aeson instances for JSON serialization, Generic deriving for automatic type class instances, XML parsing functions with xml-conduit integration, and functional programming patterns that leverage Haskell's powerful type system.

Frequently Asked Questions

What Haskell features are included in the generated data types?

The tool generates Haskell algebraic data types with strong type safety, Maybe types for nullable fields, automatic Aeson instances for JSON serialization, Generic deriving for type class instances, XML parsing functions with xml-conduit integration, and functional programming patterns that leverage Haskell's type system.

Are the generated Haskell types compatible with Aeson and Servant?

Yes! The generated Haskell data types work perfectly with Aeson for JSON serialization, Servant for web APIs, and can be used as type-safe models in functional applications. They integrate seamlessly with Haskell's ecosystem and provide compile-time guarantees for data integrity.

How does the tool handle complex XML hierarchies in Haskell?

Complex XML structures are converted to nested Haskell data types with proper relationships. Each XML element becomes an algebraic data type with appropriate fields and types, maintaining the hierarchical structure and enabling easy pattern matching and functional transformations with strong type safety.

Can I use these types with xml-conduit for XML parsing?

Absolutely! The generated Haskell data types include xml-conduit integration and parsing functions for XML processing. You can use them to parse XML documents and automatically create Haskell values from XML data using functional programming approaches and type-safe transformations.

What Haskell naming conventions are used in the generated code?

The tool follows Haskell naming conventions: data type names use PascalCase, field names use camelCase, and module names follow Haskell standards. XML attributes and elements are automatically converted to proper Haskell naming conventions with Maybe types for optional fields and strong type safety.

Is the XML to Haskell converter completely free?

Yes, completely free with no restrictions on XML complexity, file size, or usage frequency. Generate unlimited Haskell data types from XML schemas without registration, and download the complete Haskell source code for immediate integration into your Cabal or Stack projects.
