How to replace a perticular tag's content of an xml file with < instead of < ?

**Dormilich** · Feb 7 '11, 09:30 AM

your intention is correct as you need to put the content in a CDATA section. however, a CDATA section is created differently (and because of that, your "CDATA section" is inserted as comment).
a CDATA section in XML is an own node type, therefore you have to create it explicitly: DOMDocument->createCDATASec tion($textConte nt);

Thank you very much for the reply. I just test it & then tell you that if it benefits me or not...will post reply soon for this.

Code:

$doc = new DOMDocument;

$doc->load('xml_mail_format2.xml');

$playlist= $doc->documentElement;
	
$track = $playlist->getElementsByTagName("message")->item(0);
	
$data = $doc->createCDATASection($data);
	
$newTrack = $doc->createElement('message',$data);
	
$oldtrack= $track->parentNode->replaceChild($newTrack,$track);
	
$doc->saveXML();

$doc->save("xml_mail_format2.xml");

It is giving me 2 errors that :
1)Warning</b>: DOMDocument::cr eateElement() expects parameter 2 to be string, object given

2)Argument 1 passed to DOMNode::replac eChild() must be an instance of DOMNode, null given

the second error is a follow up of the first error.

you attach a CDATA node like any other node (it’s not text, after all), by DOMNode->appendChild( )

Should I send you the attachment of my xml & php file?
If you permit i send to you...I am waiting for your kind response. Thanks...

why would you need to send me the files?

**Kaushal Elsner** · Feb 7 '11, 01:31 PM

because i am not getting the thing done.I am still having errors so i asked to you. So if you permit then i will send you the 2 files.

just post the php code (and the error messages) here.

Error Message :- DOMDocument::cr eateElement() expects parameter 2 to be string, object given.

Code:

$data = $_POST['editor123'];
	
$doc = new DOMDocument;

$doc->load('xml_mail_format2.xml');

$playlist= $doc->documentElement;
	
$track = $playlist->getElementsByTagName("message")->item(0);
	
$data = $doc->createCDATASection($data);
	
$newTrack = $doc->createElement('message',$data);
	
$oldtrack= $track->parentNode->replaceChild($newTrack,$track);
		
$doc->saveXML();

$doc->save("xml_mail_format2.xml");

Can you tell me what changes should be made in the above code.Thanks in advance.

line #13 omit the second parameter, you do not have applicable text. line #14 append the CDATA node to the newly created <message> node.

**Kaushal Elsner** · Feb 7 '11, 01:52 PM

Code:

$newTrack = $doc->createElement('message');
	
$newTrack = $newTrack->appendChild($data);
	
$oldtrack= $track->parentNode->replaceChild($newTrack,$track);

Will it work?

Will it work?

try it out!

**Kaushal Elsner** · Feb 7 '11, 01:55 PM

It is not working. It gives error that:
Warning</b>: DOMNode::replac eChild() [<a href='domnode.r eplacechild'>do mnode.replacech ild</a>]: Couldn't fetch DOMCdataSection

Can you do something? It is a bit urgent, if you don't mind.

there might be issues with the variable naming, however, I got a compareable test case running:

Code:

$xml = <<<XML
<root>
    <child1/>
</root>
XML;
$doc = new DOMDocument;
$doc->loadXML($xml);

$newChild = $doc->createElement('child1');
$newCDATA = $doc->createCDATASection("<track>song 1</track>");
$newChild->appendChild($newCDATA);

$oldChild = $doc->getElementsByTagName("child1")->item(0);
$oldChild->parentNode->replaceChild($newChild, $oldChild);

echo $doc->saveXML();

output:

Code:

<?xml version="1.0"?>
<root>
    <child1><![CDATA[<track>song 1</track>]]></child1>
</root>
