Regex and / and " in Scala/Gatling

Question

I have a html response and want to save a token (bid_kid) below

<head>
    <meta name="WT.cg_n" content="Loginsider">
    <meta name="DCSext.loginPage" content="Logg inn - Din side">
    <meta content="no" http-equiv="Content-Language">
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <script type="text/javascript" src="javascript/xmlhttp.js"></script>
    <link rel="stylesheet" type="text/css" href="_public/gjeff/css/gjeff.css"/>
    <script type="text/javascript" src="_public/gjeff/js/gjeff.min.js"></script>
    <!--[if lt IE 9]>
    <script type="text/javascript" src="static/html5shiv.js"></script>
    <script type="text/javascript" src="static/respond.min.js"></script>
    <![endif]-->
    <script language="JavaScript" src="javascript/dummy_bid20_xxx.js" type="text/javascript"></script>
    <meta name="bid_kid" content="17RA18B5YKIU6A89PIZ6ED0ZYRV1KH">
    <meta name="ajaxurl" content="../no/0/ajax/loginpage-bankid">
    <script src="javascript/init_bid_helper_proto.js" type="text/javascript" defer></script>

    <title>Logg inn - here</title>
</head>

However the check I am running is appearing to be malformated in IntelliJ like this (adds two \):

.check(regex("content=\\\"(?<bid_kid>[0-9A-Z]*)\\\"").find.saveAs("token"))

Do I need to "wrap" the regex experssion in some mather to make this work in Gatling/Scala?

The regex works using a regex tester and it is like this:

content=\"(?<bid_kid>[0-9A-Z]*)\"

Thanks!

I get an error: java.util.regex.PatternSyntaxException: named capturing group is missing trailing '>' near index 15 content="(?[0-9A-Z]*)" — Magnus Jensen, Apr 23 '18 at 14:47
using what you suggest makes intellij "go orange" on the \ in \". .check(regex("content=\"(?[0-9A-Z]*)\"").find.saveAs("bidkid")) — Magnus Jensen, Apr 23 '18 at 14:48
You still do not need to escape `"` whatever you are told by IntelliJ, but as per your comment, the only problem is that you should remove `_` from the group name. Change `bid_kid` to `bidkid`, or just replace the named capturing group with a simple numbered one, i.e. `regex("content=\"([0-9A-Z]*)\"")` — Wiktor Stribiżew, Apr 23 '18 at 14:50

Acc. to the Java regex documentation, the named group syntax does not allow underscores:

A capturing group can also be assigned a "name", a named-capturing group, and then be back-referenced later by the "name". Group names are composed of the following characters. The first character must be a letter.

The uppercase letters 'A' through 'Z' ('\u0041' through '\u005a'),

The lowercase letters 'a' through 'z' ('\u0061' through '\u007a'),

The digits '0' through '9' ('\u0030' through '\u0039'),

Thus, you should change your code to

.check(regex("content=\\\"(?<bidkid>[0-9A-Z]*)\\\"").find.saveAs("token"))
