**[mdast][]** utility to get the plain text content of a node.
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
[npm][]:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm install mdast-util-to-string
|
||
|
|
```
|
||
|
|
|
||
|
|
## Use
|
||
|
|
|
||
|
|
```js
|
||
|
|
var unified = require('unified')
|
||
|
|
var parse = require('remark-parse')
|
||
|
|
var toString = require('mdast-util-to-string')
|
||
|
|
|
||
|
|
var tree = unified()
|
||
|
|
.use(parse)
|
||
|
|
.parse('Some _emphasis_, **importance**, and `code`.')
|
||
|
|
|
||
|
|
console.log(toString(tree)) // => 'Some emphasis, importance, and code.'
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
### `toString(node)`
|
||
|
|
|
||
|
|
Get the text content of a [node][] or list of nodes.
|
||
|
|
|
||
|
|
The algorithm checks `value` of `node`, then `alt`, and finally `title`.
|
||
|
|
If no value is found, the algorithm checks the children of `node` and joins them
|
||
|
|
(without spaces or newlines).
|
||
|
|
|
||
|
|
> This is not a markdown to plain-text library.
|
||
|
|
> Use [`strip-markdown`][strip-markdown] for that.
|
||
|
|
|
||
|
|
## Security
|
||
|
|
|
||
|
|
Use of `mdast-util-to-string` does not involve **[hast][]**, user content, or
|
||
|
|
change the tree, so there are no openings for [cross-site scripting (XSS)][xss]
|
||
|
|
attacks.
