How to find text in response in html format?

Question

I have part of code:

    await fetch(request)
      .then((response) => {
        if (response.status === 200) {
          console.log("Success");
          result = response.text();
        } else {
          throw new Error("Something went wrong on API server!");
        }
      });
    console.log(await result);

I received response in the html format. Part of response:

[0-0]     <input class="form-control" data-val="true" data-val-number="The field Maximum days in advance an online reservation can be made must be a number." data-val-range="The field Maximum days in advance an online reservation can be made must be between 1 and 366." data-val-range-max="366" data-val-range-min="1" data-val-required="The Maximum days in advance an online reservation can be made field is required." id="MaxFutureReservationTimeDays" name="MaxFutureReservationTimeDays" onkeypress="return event.charCode === 13 || (event.charCode >= 48 &amp;&amp; event.charCode &lt;= 57)" type="number" value="20" />

How can I find some value in this text and store it in a variable? For example value="20" for MaxFutureReservationTimeDays. Thanks.

I tried use

string.includes(word);
