title: Zoho XML formatting issue
body: <p>I'm sending form data to ZOHO CRM. I'm adding some variables into the XML variable as follows.</p>
  
  <pre><code> $xml = 
      '&lt;?xml version="1.0" encoding="UTF-8"?&gt;
      &lt;Leads&gt;
      &lt;row no="1"&gt;
      &lt;FL val="First Name"&gt;'.$name.'&lt;/FL&gt;
      &lt;FL val="Last Name"&gt; &lt;/FL&gt;
      &lt;FL val="Email"&gt;'.$email.'&lt;/FL&gt;
      &lt;FL val="Phone"&gt;'.$phone.'&lt;/FL&gt;
      &lt;FL val="Zip Code"&gt;'.$zip.'&lt;/FL&gt;
      &lt;FL val="Description"&gt;'.$lessonType.'&lt;/FL&gt;
      &lt;FL val="Lead Source"&gt;web&lt;/FL&gt;
      &lt;FL val="Referrer URL"&gt;'.$refURL.'&lt;/FL&gt;
      &lt;/row&gt;
      &lt;/Leads&gt;';
  </code></pre>
  
  <p>But when I do this I get the following error.</p>
  
  <blockquote>
    <p>4600Unable to process your request. Please verify if the name and
    value is appropriate for the "xmlData" parameter.</p>
  </blockquote>
  
  <p>When I replace the variables in the $xml variable with static value and removed concatenation, it is successfully submitted. </p>
  
  <p>Please let me know how to fix this.</p>
  
  <p>Thanks
