hast-util-is-element

hast utility to check if a node is a (certain) element.

Install

npm:

npm install hast-util-is-element

Use

var is = require('hast-util-is-element')

is({type: 'text', value: 'foo'}) // => false

is({type: 'element', tagName: 'a'}, 'a') // => true

is({type: 'element', tagName: 'a'}, ['a', 'area']) // => true

API

isElement(node[, test[, index, parent[, context]]])

Check if the given value is a (certain) element.

• node (Node) — Node to check.
• test (Function, string, or Array.<Test>, optional) — When array, checks if any one of the subtests pass. When string, checks that the element has that tag name. When function, see test
• index (number, optional) — Index of node in parent
• parent (Node, optional) — Parent of node
• context (*, optional) — Context object to invoke test with

Returns

boolean — Whether test passed and node is an Element.

Throws

Error — When an incorrect test, index, or parent is given. A node that is not a node, or not an element, does not throw.

function test(element[, index, parent])

Parameters

• element (Element) — Element to check
• index (number?) — Index of node in parent
• parent (Node?) — Parent of node

Context

* — The to is given context.

Returns

boolean? — Whether element matches.

isElement.convert(test)

Create a test function from test, that can later be called with a node, index, and parent. Useful if you’re going to test many nodes, for example when creating a utility where something else passes a compatible test.

The created function is slightly faster because it expects valid input only. Therefore, passing invalid input, yields unexpected results.

Can also be accessed with require('hast-util-is-element/convert').

Security

hast-util-is-element does not change the syntax tree so there are no openings for cross-site scripting (XSS) attacks.
