title: Google DataStudio - regex to extract first part of page title, before > character
body: <p>DataStudio shows each page of a report separately, in this format</p>
  
  <pre><code>Report 1 &gt; Page 1
  Report 1 &gt; Page 2
  Report 2 &gt; Page 4
  etc
  </code></pre>
  
  <p>I'm trying to show sessions for Reports only, regardless of page. 
  I created a calculated field "Report Name", using this regex to get everything up to the > character:</p>
  
  <p><code>REGEXP_EXTRACT(Page Title,'^.+?&gt;')</code></p>
  
  <p>But it doesn't work. 
  This is the Google-RE2 syntax <a href="https://github.com/google/re2/wiki/Syntax" rel="nofollow noreferrer">https://github.com/google/re2/wiki/Syntax</a></p>
