HI everyone,
anyone has an idea about how to access cdata in php here is the structure of my xml so you can have a clear idea
<call-handling id=”1″ code=”0″ name=”My status=”on”>
– <![CDATA[
<user-script><incoming-call status=”on”><anonymous-filter status=”off” baring-type=”voicemail”/>
<reject status=”off/></incoming-call></user-script>
]]>
</call-handling>

i need to access the tag reject for example . I am usign php5 and the Dom function
$dom = new DomDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXML($str);
$params = $dom->getElementsByTagName(‘reject’);
foreach ($params as $reject ) {
echo $reject -> getAttribute(‘status’);
}

@nihaauthorOct 16.2006 — ok i resolved it using this

$str = str_replace("<![CDATA[","",$str);

$str = str_replace("]]>","",$str);

$dom = new DomDocument;
$dom->preserveWhitespace = false;
$dom->loadXML($str);
$params = $dom->getElementsByTagName('reject');

foreach ($params as $reject )
{

echo $reject -> getAttribute('status');
}

thanks anyway

@chazzyOct 16.2006 — what happens when you just got the call handling as a text node?

nevermind, PHP's handling of XML seems very limited.

Also, bokeh's assertion while the end result is correct, the assertion is wrong. <![CDATA elements reside as part of the "DOMText" of an element. PHP has no way of retrieving the DOMText of an element it seems. You can try using DOMCharacterData -> substringData(offset...) to get it as well.

http://us3.php.net/manual/en/function.dom-domcharacterdata-substringdata.php

Why exactly is this additional dom document enclosed in CDATA in the first place? Is this some sort of plugin material?
