title: Combining one or more characters (`+?`) and positive lookahead (?=)
body: <p>I have a string like this:</p>
  
  <pre><code>"resourceType": "com.bmc.arsys.rx.services.view.domain.ContainerViewComponentDefinition",
  </code></pre>
  
  <p>I want to match the first double quote in this part:</p>
  
  <pre><code>"resourceType":
  </code></pre>
  
  <p>So I construct a regexp to find <code>"</code>, then one or more characters (greedy) followed by <code>":</code> literals, so I have the first part:</p>
  
  <pre><code>".+?
  </code></pre>
  
  <p>and then I want to add positive lookahead part <code>?=":</code></p>
  
  <pre><code>".+??=":
  </code></pre>
  
  <p>but I get syntax error. What's the syntax for combining them?</p>
