title: Intercept response in XML with chosen file (in .xml format, too) and parse it into Cypress
body: <p>since that I am new in Cypress, hope that anyone can help.
  Namely, have .xml response body saved in file inside cypress folder (actually at, /fixtures/file.xml). What I am trying to achieve to somehow parse xml into JS object, in order to write test which will check several articles (and each of it has: thumbnail, title, impress text - usual elements).
  What acchieved so far - found that file, printed it on console.log</p>
  <pre><code>cy.route('**{part_of_URL_response**', 'fixture:file.xml').as(
    'articlePosts',
   );
  });
  
  it('should contain list of articles', () =&gt; {
  cy.readFile('cypress/fixtures/file.xml').then(articlePosts  
  =&gt; {
     cy.get(articlePosts).should('exist');
    });
  </code></pre>
  <p>But, assertion line is not working properly, not understand why.
  Is that assertion correct - just want to confirm element existence?
  Is there any solution to convert/parse file.xml into JS object(s) and iterate later, to assert elements on page?</p>
