How to display XML in HTML in PHP?

Question

I have a string with XML:

$string = 
"
<shoes>
    <shoe>
       <shouename>Shoue</shouename>
    </shoe>
</shoes>
";

And would like display it on my website like this:

This is XML string content:
<shoes>
    <shoe>
       <shouename>Shoue</shouename>
    </shoe>
</shoes>

So I would like to do it:

• on site, not in textbox
• without external libraries, frameworks etc.
• formatted with proper new lines
• formatted with tabs
• without colors etc., only text

So how to do it in plain and simple way?

Answer 1

If you just want a plain-text representation of your (pre-formatted) string, you can wrap it in HTML <pre/> tags and use htmlentities to escape the angle brackets:

<?PHP echo '<pre>', htmlentities($string), '</pre>'; ?>
