PHP, XML, CDATA & HTML entities

[tomccabe]

I have an XML file like such:

<spice>
	<sections>
		<contact></contact>
		<products></products>
		<people></people>
		<homes></homes>
		<harvest></harvest>
		<contactCopy> 
			<banners><![CDATA[Lots of <u>text</u> with tons of <a href="#">links</a> and <i>other</i> markup.]]></banners>
		</contactCopy>
		<homesCopy>
			<banners><![CDATA[Lots of <u>text</u> with tons of <a href="#">links</a> and <i>other</i> markup.]]></banners>
		</homesCopy>
		<productsCopy>
			<banners><![CDATA[Lots of <u>text</u> with tons of <a href="#">links</a> and <i>other</i> markup.]]></banners>
		</productsCopy>
		<peopleCopy>
			 <banners><![CDATA[Lots of <u>text</u> with tons of <a href="#">links</a> and <i>other</i> markup.]]></banners>
		</peopleCopy>
		<harvestCopy>
			<banners><![CDATA[Lots of <u>text</u> with tons of <a href="#">links</a> and <i>other</i> markup.]]></banners>
		</harvestCopy>	
	</sections>
</spice>

What I need to be able to do is pull the CDATA content out, WITH the tags intact, have the client edit the content with a markup editor and put unentitied HTML back into the CDATA section. I have been able to pull the content out of the CDATA field with

$doc = new DomDocument();
$file = "spice.xml";
$doc->load($file);
$xPath = new DomXPath($doc);
$homesCopy 	= $xPath->query("//sections/homesCopy/banners");
echo $homesCopy->item(0)->nodeValue;

but I cannot for the life of me figure out how to simply edit that content and put it back without turning the HTML tags into their entities.

How do you know which banner you are editing at any given time? I was expecting to see each banner node with a unique id attribute so that when you edit, you would know which node to update. Where's your attempted update code?

assuming you are POSTing from a form with <input name='homesCopy'> try:

<?php
$doc = new DomDocument();
$file = "spice.xml";
$doc->load($file);
$xPath = new DomXPath($doc);
$homesCopy 	= $xPath->query("//sections/homesCopy/banners")->item(0);
if( isset($_POST['homesCopy']) ){
  $homesCopy->firstChild->nodeValue=$_POST['homesCopy'];
  $doc->save($file);
}
echo $homesCopy->nodeValue;
?>
