PHP XML Object To HTML Friendly Text String?

[KomaZoame]

I'm using PHP5 and it's inbuilt SOAP functionality. I'm catching the SOAP Fault errors, and email myself when one is triggered. What I really need to do is include the __getLastRequest() and __getLastResponse(), however as these are XML objects, when I try to include them by echoing them into the body of my HTML email, for obvious reasons they don't appear in full.Is there a function or class I can use to convert these objects into a HTML friendly string?I've googled this but without any joy. If possible i'd like to avoid using a class external to PHPs own functionality but if needs must i'll have to.EDITED:How can I format the following XML so that it gives me an indented browser friendly version?\[code\]<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="schemas.xmlsoap.org/soap/envelope/"; xmlns:ns1="xxx.com/"><SOAP-ENV:Body><ns1:Ad
