What is this?

This package is a utility that takes a xast node and gets its plain-text value. This is like the DOMs Node#textContent getter but there are some small deviations.

When should I use this?

This is a small utility that is useful when you want a plain-text version of a node when working with xast (XML).

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install xast-util-to-string

In Deno with esm.sh:

import {toString} from 'https://esm.sh/xast-util-to-string@3'

In browsers with esm.sh:

<script type="module">
  import {toString} from 'https://esm.sh/xast-util-to-string@3?bundle'
</script>

Use

import {x} from 'xastscript'
import {toString} from 'xast-util-to-string'

const tree = x(
  'ncx',
  {xmlns: 'http://www.daisy.org/z3986/2005/ncx/', version: '2005-1'},
  [
    x('head', [
      x('meta', {name: 'dtb:uid', content: 'urn:isbn:9781234567891'})
    ]),
    x('docTitle', [x('text', 'A Christmas Carol')]),
    x('docAuthor', [x('text', 'Charles Dickens')])
  ]
)

console.log(toString(tree))

Yields:

A Christmas CarolCharles Dickens

API

This package exports the identifier toString. There is no default export.

toString(node)

Get the plain text value of a node.

If the node has a value field (cdata, comment, doctype, instruction, or text), returns it. If the node has a children field (root or element), recurses into it to concatenate all texts.

Returns

Serialized node (string).

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, xast-util-to-string@^3, compatible with Node.js 16.

Security

xast-util-to-string does not change the syntax tree so there are no openings for cross-site scripting (XSS) attacks.
