extracting CDATA from xml generated code

PHP

I have following website URL which is http://www.wheels4rent.net/test00.html

When data is entered a PHP is generated from XML and example given below of XML

You can get a quotation with a call like this: location UK001 (Heathrow) 10/10/2011 09:00 - 12/10/2011 10:00 Manual cars only

http://www.thrifty.co.uk/cgi-bin/gen5?runprog=thxml&xsrc=7qhfqou3&mode=quote&xloc=UK001&
amp;xpuyear=2011&xpumonth=10&xpuday=10&xputime=
09:00&xdbyear=2011&xdbmonth=10&xdbday=12&xdbtime=10:00&
xclass=M
This will give a list of cars at the specified location and i have done this ok using php. You can see result from www.wheels4rent.net/test00.html and put in location and date.

From this one can retrieve data from list_car.php when 'go' button clicked.list_car.php is shown below.

<?php
//ini_set("disable_functions",null);
//phpinfo();

$string="http://www.thrifty.co.uk/cgi-bin/gen5?runprog=thxml&xsrc=7qhfqou3&mode=quote";

From the http://www.wheels4rent.net/list_car.php i have all the required info except a booking button which i require and when a particular car is booked then the CDATA info is given but unsure how to integrate the CDATA at present. Any pointers would be appreciated. The CDATA info is in the <book> section of the XML(click on 1st link given to view)
