Need to display raw XML in a textarea

I have a test harness that needs to display the actual XML data returned from a messaging system. Currently the result gets displayed in a <textarea>, but any XML entities such as &amp; get displayed by the browser as the translated value &

As I am trying to display the 'real' XML returned by the application, this is a bit of a problem. I don't really want to modify the data prior to display in case this introduces artefacts, is there a way to prevent entity substitution in the same way as <pre> does for formatting?

Sadly, no. The test harness is a J2EE app, the HTML is only used to display the results. I just want to display the 'real' result rather than my browser's interpretation of it.

Ended up doing a String.replaceAll("&", "&amp;") on the XML string before rendering it.

This gets over the problem of the browser interpreting any XML entities in the string, and allows the resulting display to be cut and pasted into other tools without error.

An easier way would be to place it in a javascript variable then call a function to populate your xml

Code: 
<script>
var xml = " <?xml version='1.0'?> <bookstore>   <book category='cooking'>      <title lang='en'>         everyday italian      </title>      <author>         giada de laurentiis      </author>      <year>         2005      </year>      <price>         30.00      </price>   </book>   <book category='children'>      <title lang='en'>         harry potter      </title>      <author>         j k. rowling      </author>      <year>         2005      </year>      <price>         29.99      </price>   </book>   <book category='web'>      <title lang='en'>         xquery kick start      </title>      <author>         james mcgovern      </author>      <author>         per bothner      </author>      <author>         kurt cagle      </author>      <author>         james linn      </author>      <author>         vaidyanathan nagarajan      </author>      <year>         2003      </year>      <price>         49.99      </price>   </book>   <book category='web'>      <title lang='en'>         learning xml      </title>      <author>         erik t. ray      </author>      <year>         2003      </year>      <price>         39.95      </price>   </book></bookstore>";
</script>
<html>
<head></head>
<body body onload="document.getelementbyid('mytextarea').value = xml;">
<form>
<input type="textarea" id="mytextarea" value="" >
</form>
</body>
</html>

I don't know the answer but my good friend Google does.

I'll give it a try, but I'm not convinced. I don't see any XML entities in your example...

I wouldn't use a javascript method as this may not work for all users. Are you using a server-side language to serve these pages?

JSP. That's why it was easy enough to stick in the replaceAll(). Good point about the JavaScript, however - you can just turn it off in the browser, so it's not very robust.
