XML parser for Deno

Features

Follow XML.com’s Converting between XML and JSON patterns.

• Support basic XML (tags, self-closed tags, nested tags, attributes, …)
• Support XML.parse and XML.stringify
• Support <?xml ?> prolog declaration
• Support <!DOCTYPE> declaration
• Support <![CDATA[ ]] strings
• Support XML entities (&, &, &, …)
• Support revivers for custom parsing
• Auto-group nodes into arrays when same tag is used
• Auto-unwrap nodes when it only has text content

Limitations

• Comments are stripped and cannot be recovered
• When using mixed content of texts and child nodes, text node will be stripped and cannot be recovered
• When using mixed group of nodes, XML.stringify(XML.parse())) may result in different order
  • Example: <a><b/><c/><b/></a> will result in <a><b/><b/><c/></a>
  • This may or may not be acceptable depending on your use case

⚠️ XML.stringify is not implemented yet

Basic usage

import { parse, stringify } from "https://deno.land/x/xml/mod.ts";

const data = parse(`<hello lang="en" charset="utf8">world</hello>`);
console.log(data);
/*
{
  hello:{
    "@lang":"en",
    "@charset":"utf8",
    $:"world",
  }
}
*/

Revivers

By default, node contents will be converted to:

• null when empty, unless emptyToNull = false
• number when matching finite numbers, unless reviveNumbers = false
• boolean when matching true or false (case insensitive), unless reviveBooleans = false

XML entities (e.g. &, &, &, …) will be unescaped automatically.

You can also provide a custom reviver that will receive key, value and tag.
