XML editing problem

dwcharn

Hey guys - I am pretty new to php but do a lot of actionscript work in Flash. I am in a bit of a bind (deadline) and need some php help.

Basically I have a XML file that is very simple:

<theArticles>
<article>
<text>hello</text>
</article>
</theArticles>

I am sending a string from Flash to PHP (I know how to do this part) and need PHP to open a XML file (if it exists or create if it doesnt), and tack on a new node (<article><text>hello 2</text></article>). So I need to open up the XML and add the new <article> info in. I was thinking maybe I can open the file, remove the "</theArticles>" end tag, place the new <article></article> in at the end and then add the </articles> back on the end to close the XML and then close the XML file.

I have been trying to play around with some ideas but I just don't know how to do this. This is for a personal project I am doing and I have a few other company projects that are going to take up too much of my time this week. I would love to learn this better but I just don't have the time for weeks. Any help would be greatly appreciated. Thanks everyone.

Here is a great link!

Especially when it talks about appeding a child element (which is I believe what you were asking for). 🙂

Ok, I have below a script I wrote up to try and do what I need but it doesn't seem to work (I get a lot of errors about the $xml = simpleXMLElments($xml) line.
So basically I have an XML file written like this:

<articleResponses>
<articleResponse>
<writtenBy>Joe Somebody</writtenBy>
<response>Nice job on that article!</response>
</articleResponse>
</articleResponses>

And I want to add in a new <articleResponse> element and children. What I want my below script to do is give me this:

<articleResponses>
<articleResponse>
<writtenBy>Joe Somebody</writtenBy>
<response>Nice job on that article!</response>
</articleResponse>
<articleResponse>
<writtenBy>Becky Miller</writtenBy>
<response>Good job.</response>
</articleResponse>
</articleResponses>

And... here is my code. I hope it somewhat makes sense. Thanks so much for any help.

<?php
$filename = 'testxml.xml';
// open file so I can save it later
$theCommentsFile = fopen($filename, 'r+') or die("can't open file");
//open file in simpleXML
$xml = simplexml_load_file($filename);

$addElement = new SimpleXMLElement($xml);
// Create new <articleResponse></articleResponse> element
$new_response = $addElement->addChild('articleResponse');
// Create Children under the new element
$new_response->addChild('writtenBy', 'Becky Miller');
$new_response->addChild('response', 'Good job.');

// Make new element into XML
$addElement ->asXML();

// Add the new element as a child to the main <articleResponses> element
$xml->addChild($addElement);

$newXML = $xml->asXML();
echo $newXML;

// Write the old and new Elements back to the XML file
fwrite($theCommentsFile, $newXML);
// Close the XML file
fclose($theCommentsFile);
?>
