What is this?
This package is a utility that can turn a parse5 tree into a hast tree.
When should I use this?
You can use this package when using parse5 as an HTML parser and wanting to
work with hast.
The utility hast-util-to-parse5 does the
inverse of this utility.
It generates parse5s AST again.
The utility hast-util-from-html wraps this
utility and parse5 to both parse HTML and generate hast from it.
Install
This package is ESM only. In Node.js (version 16+), install with npm:
1npm install hast-util-from-parse5
In Deno with esm.sh:
1import {fromParse5} from "https://esm.sh/hast-util-from-parse5@8"
In browsers with esm.sh:
1<script type="module"> 2 import {fromParse5} from "https://esm.sh/hast-util-from-parse5@8?bundle" 3</script>
Use
Say our document example.html contains:
1<!doctype html><title>Hello!</title><h1 id="world">World!<!--after-->
…and our module example.js looks as follows:
1import {fromParse5} from 'hast-util-from-parse5' 2import {parse} from 'parse5' 3import {read} from 'to-vfile' 4import {inspect} from 'unist-util-inspect' 5 6const file = await read('example.html') 7const p5ast = parse(String(file), {sourceCodeLocationInfo: true}) 8const hast = fromParse5(p5ast, {file}) 9 10console.log(inspect(hast))
…now running node example.js yields:
1root[2] (1:1-2:1, 0-70) 2│ data: {"quirksMode":false} 3├─0 doctype (1:1-1:16, 0-15) 4└─1 element<html>[2] 5 │ properties: {} 6 ├─0 element<head>[1] 7 │ │ properties: {} 8 │ └─0 element<title>[1] (1:16-1:37, 15-36) 9 │ │ properties: {} 10 │ └─0 text "Hello!" (1:23-1:29, 22-28) 11 └─1 element<body>[1] 12 │ properties: {} 13 └─0 element<h1>[3] (1:37-2:1, 36-70) 14 │ properties: {"id":"world"} 15 ├─0 text "World!" (1:52-1:58, 51-57) 16 ├─1 comment "after" (1:58-1:70, 57-69) 17 └─2 text "\n" (1:70-2:1, 69-70)
API
This package exports the identifier fromParse5.
There is no default export.
fromParse5(tree[, options])
Transform a parse5 AST to hast.
Parameters
tree(Parse5Node) —parse5tree to transformoptions(Options, optional) — configuration
Returns
hast tree (HastNode).
Options
Configuration (TypeScript type).
Fields
file
File used to add positional info to nodes
(VFile, optional).
If given, the file should represent the original HTML source.
space
Which space the document is in
(Space, default: 'html').
When an <svg> element is found in the HTML space,
this package already automatically switches to and from the SVG space when
entering and exiting it.
verbose
Whether to add extra positional info about starting tags,
closing tags,
and attributes to elements
(boolean, default: false).
👉 Note: only used when
fileis given.
For the following HTML:
1<img src="http://example.com/fav.ico" alt="foo" title="bar">
The verbose info would looks as follows:
1{ 2 type: 'element', 3 tagName: 'img', 4 properties: {src: 'http://example.com/fav.ico', alt: 'foo', title: 'bar'}, 5 children: [], 6 data: { 7 position: { 8 opening: { 9 start: {line: 1, column: 1, offset: 0}, 10 end: {line: 1, column: 61, offset: 60} 11 }, 12 closing: null, 13 properties: { 14 src: { 15 start: {line: 1, column: 6, offset: 5}, 16 end: {line: 1, column: 38, offset: 37} 17 }, 18 alt: { 19 start: {line: 1, column: 39, offset: 38}, 20 end: {line: 1, column: 48, offset: 47} 21 }, 22 title: { 23 start: {line: 1, column: 49, offset: 48}, 24 end: {line: 1, column: 60, offset: 59} 25 } 26 } 27 } 28 }, 29 position: { 30 start: {line: 1, column: 1, offset: 0}, 31 end: {line: 1, column: 61, offset: 60} 32 } 33}
Space
Namespace (TypeScript type).
Type
1type Space = 'html' | 'svg'
Types
This package is fully typed with TypeScript.
It exports the additional types Options and
Space.
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,
hast-util-from-parse5@8,
compatible with Node.js 16.
Security
Use of hast-util-from-parse5 can open you up to a
cross-site scripting (XSS) attack if Parse5’s AST is unsafe.
