Parse XML into structured JavaScript objects with type safety and validation.

📦 Array Handling

Section titled “📦 Array Handling”

Extract arrays of elements from XML documents using XPath selectors.

🔄 Transformations

Section titled “🔄 Transformations”

Apply custom transformation functions to parsed data for data manipulation.

✅ Validation

Section titled “✅ Validation”

Enforce constraints on your data with built-in validation methods like min(), max(), and int().

📰 RSS Feeds

Section titled “📰 RSS Feeds”

Parse real-world RSS feed structures with nested arrays and complex schemas.

🏷️ Attributes

How to Use

Section titled “How to Use”
  1. Choose an Example: Click one of the quick example buttons to load a pre-configured scenario
  2. Edit the XML: Modify the XML input to test different structures
  3. Adjust the Schema: Change the schema definition to match your XML structure
  4. Select Mode: Choose between Sync (string-based) or Async (ReadableStream-based) parsing
  5. Parse: Click the “Parse XML” button to see the result
  6. Upload Files: Test with your own XML files (up to 10MB)

Performance Metrics

Section titled “Performance Metrics”

The demo tracks:

  • Parse Time: How long it took to parse the XML
  • Mode: Whether sync or async parsing was used
  • XML Size: The size of your input XML
  • Throughput: Processing speed in KB/s

Try It in Your Project

Section titled “Try It in Your Project”

Once you’ve experimented with the demo, install stax-xml in your project:

Terminal window
npm install stax-xml

Then use the same patterns from the demo:

import { x } from 'stax-xml/converter';


const schema = x.object({
  title: x.string().xpath('/book/title'),
  author: x.string().xpath('/book/author'),
  price: x.number().xpath('/book/price')
});


const result = schema.parseSync(xmlString);
