title: How to use client.read() to read string between two characters?
body: <p>In my ESP8266 WiFi project I'm getting characters from a website through a GET request. The current code is this:</p>
  
  <pre class="lang-cpp prettyprint-override"><code>while(client.available()){
      String line = client.readStringUntil('\r');
      Serial.print(line);
  }
  </code></pre>
  
  <p>To get a string between particular characters, how do I edit this?</p>
