$ npm install find-conditional-comments
const findConditionalComments = require('find-conditional-comments');
const html = `
<!--[if mso]>
Hello, Microsoft Outlook!
<![endif]-->
`
findConditionalComments(html);
//=> [ { open: "<!--[if mso]>", close: "<![endif]-->", range: [1, 63], downlevel: "hidden" } ]Returns an Array of Objects for each comment with the following properties:
boolean
Whether the comment is an HTML comment. This might be false for certain items when downlevel is revealed.
String
Opening portion of the conditional comment.
String
Closing portion of the conditional comment.
boolean
Whether the comment "bubbles" around the value.
When true, the comment is visible to all platforms except those that support conditional comments.
<!--[if !mso]>-->
Hello, Not Microsoft Outlook!
<!--<![endif]-->
When false, the comment is hidden from all platforms except those that support conditional comments.
<!--[if mso]>
Hello, Microsoft Outlook!
<![endif]-->
String
Either hidden or revealed.
hidden means the comment is hidden from all platforms except those that support conditional comments.
revealed means the comment is visible to all platforms except those that support conditional comments.
This is very similar to the bubble property, but it's not the same.
downlevel always be revealed if bubble is true.
But bubble can be true even if downlevel is hidden when using this syntax:
<![if lt IE 8]>
<p>Please upgrade to Internet Explorer version 8.</p>
<![endif]>
Array
A range array containing the start and end indices of the comment.
