    regex-empty-conditional-comments

    Regular expression for matching HTML empty conditional comments

    Install

    The latest version is ESM only: Node 12+ is needed to use it and it must be imported instead of required. If your project is not on ESM yet and you want to use require, use an older version of this program, 1.11.0.

    npm i regex-empty-conditional-comments

    Quick Take

    import { strict as assert } from "assert";
    
    import { emptyCondCommentRegex } from "regex-empty-conditional-comments";
    
    // empty comment which was meant to target Outlook-only
    assert.equal(
      emptyCondCommentRegex().test(`<!--[if !mso]>
    <![endif]-->`),
      true
    );
    
    // empty comment which was meant to target non-Outlook-only
    assert.equal(
      emptyCondCommentRegex().test(`<!--[if !mso]><!-- -->
    <!--<![endif]-->`),
      true
    );
    
    assert.equal(
      emptyCondCommentRegex().test(`<!--[if !mso]><!-- -->
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <!--<![endif]-->`),
      false
    );
    
    assert.equal(
      emptyCondCommentRegex().test(`<!--[if gte mso 9]><xml>
    <o:OfficeDocumentSettings>
    <o:AllowPNG/>
    <o:PixelsPerInch>96</o:PixelsPerInch>
    </o:OfficeDocumentSettings>
    </xml><![endif]-->`),
      false
    );
    
    assert.equal(
      emptyCondCommentRegex().exec("<html><!--[if !mso]><![endif]--><title>")[0],
      "<!--[if !mso]><![endif]-->"
    );
    
    assert.deepEqual(
      `<html> <!--[if !mso]><![endif]--> <title>text</title> <!--[if gte mso 9]>
    <xml>
    <![endif]-->`.match(emptyCondCommentRegex()),
      ["<!--[if !mso]><![endif]-->"]
    );
