I’m generating a ton of XML that is to be passed to an API

  • 0

I’m generating a ton of XML that is to be passed to an API as a post variable when a user click on a form button. I also want to be able to show the user the XML before hand.

The code is sorta like the following in structure:

<?php     $lots of = 'php'; ?>  <xml>     <morexml>  <?php     while(){ ?>     <somegeneratedxml> <?php } ?>  <lastofthexml>  <?php ?>  <html>     <pre>       The XML for the user to preview     </pre>      <form>         <input id='xml' value='theXMLagain' />     </form> </html>

My XML is being generated with a few while loops and stuff. It then needs to be shown in the two places (the preview and the form value).

My question is. How do I capture the generated XML in a variable or whatever so I only have to generate it once and then just print it out as apposed to generating it inside the preview and then again inside the form value?
