hast-util-to-xast
hast (HTML / SVG) utility to transform trees to xast (XML).
Install
npm:
npm install hast-util-to-xast
Use
Say we have an example.html file, that looks as follows:
<!doctypehtml>
<title>Hello, World!</title>
<h1>👋, 🌍</h1>
…and our script, example.js, looks as follows:
var fs = require('fs')
var unified = require('unified')
var parse = require('rehype-parse')
var toXast = require('hast-util-to-xast')
var toXml = require('xast-util-to-xml')
// Get the HTML syntax tree:
var hast = unified()
.use(parse)
.parse(fs.readFileSync('example.html'))
// Turn hast to xast:
var xast = toXast(hast)
// Serialize xast:
console.log(toXml(xast))
Yields:
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head><title>Hello, World!</title>
</head><body><h1>👋, 🌍</h1>
</body></html>
API
toXast(node[, space|options])
Transform the given hast tree to xast.
space
Treated as options.space.
options
options.space
Whether the root of the tree is in the 'html' or 'svg' space (enum, 'svg' or 'html', default: 'html').
If an svg element is found in the HTML space, toXast automatically switches to the SVG space when entering the element, and switches back when exiting.
You can also switch explicitly with xmlns properties in hast, but note that only HTML and SVG are supported.
Security
Both HTML and XML can be a dangerous language: don’t trust user-provided data. Use hast-util-santize to make the hast tree safe before using this utility.
