About
Features
- Validate XML data syntactically
- Transform XML to JSON or Nimn
- Transform JSON back to XML
- Works with node packages, in browser, and in CLI (press try me button above for demo)
- Faster than any pure JS implementation.
- It can handle big files (tested up to 100mb).
Various options are available to customize the transformation
- You can parse CDATA as separate property.
- You can prefix attributes or group them to separate property. Or can ignore them from result completely.
- You can parse tag's or attribute's value to primitive type: string, integer, float, or boolean. And can optionally decode for HTML char.
- You can remove namespace from tag or attribute name while parsing
- It also supports boolean attributes.
