how to hyperlink CDATA in PHP

[alltech]

i have comparison website and a deep link in xml is given when parameters are input. However i have CDATA which is always changing depending on what booking parameters are. This CDATA is a URL followed by code. I need to be able to select the CDATA when a 'submit' button is clicked. any ideas. below is PHP code that provides parameters such as location, time, etc but stuck on CDATA. The CDATA is within <book> section of XML.

 Thanks for this but cannot seem to make this work. When i do i just get the URL string listed on the webpage?. Here is the list_car1.php file.
 
 
 
var timeout;
function checkLoccode(sobj) {
if (sobj.options[sobj.selectedIndex].value=='--other countries--') {
//getUrl('GET', 'http://' + location.host + '/cgi-bin/gen5?runprog=thajaxlog&log=prepaid_from_home', true, ajaxLogCallBack);
timeout=setTimeout("callRedirect()",3000);
}
}
function ajaxLogCallBack() {
if (requestObject.readyState == 4) {
if (requestObject.status==200) {
clearTimeout(timeout);
callRedirect();
}
}
}
function callRedirect() {
location.href='http://worldwide.thrifty.com';
}

I don’t see any CDATA* in your code … besides, XMLHttpRequest.responseText only has the data type string.


* - <![CDATA[this is the CDATA content]]>

[alltech]

The CDATA is generated from the following for example see following code which is generated when vehicle picked up from heathrow..this link gives XML and within this CDATA is there for each car

@alltech

[Dormilich]

you access it like a standard text node, e.g. //book

[alltech]

@Dormilich
can you give me example if possible????

[Dormilich]

in PHP or in JavaScript?

[alltech]

give example in PHP please

[Dormilich]

<?php
$ex = <<<DOC
<?xml version="1.0" ?>
<root>
    <item>1</item>
    <item><![CDATA[<2>]]></item>
</root>
DOC;
$xml = new DOMDocument;
$xml->loadXML($ex);
echo $xml->getElementsByTagName("item")->item(1)->firstChild->data;
