XML with PHP

**Moshambi** · 02-10-2009, 03:30 AM

Hello everyone,

I am wondering if there is some way to open an XML document, make changes to it and then save the changes. I specifically want to know if there is a way that I can add new elements to the document. I have searched the net for this and have not been able to come up with anything so now I'm asking the pros. Thanks in advance!

I don't know if there is an xml function you can use... But you can try making your own with:

file_put_contents & file_get_contents
fgetcsv
fwrite

Maybe some of those.

The SimpleXML object is the quickest way to go about this. Post again if you need help with it.

I'm not a pro, but

http://www.php.net/manual/en/book.simplexml.php

Is fairly straight forward. I played with it for a couple hours and then felt fairly comfortable.

Didn't see Tim's post. Sry.

Ok ya I had been looking at the simpleXMLElement stuff before I posted this but I still can't figure out a way to add an element to the xml document then save it. For example:

XML Doc before I run Code:

Code:

<?xml version="1.0"?>
<body>
	<element>text</element>
</body>

XML Doc after Code:

Code:

<?xml version="1.0"?>
<body>
	<element>text</element>
	<element>text</element>
</body>

Does this make any sense? I tried using the addChild() function but I don't know how to get it to save itself. I tried $variable->saveXML();

It will output it but it won't actually save it to the document?

Thanks for the help,

Mosh

Code:

<?xml version="1.0"?>
<body>
	<element>text</element>
</body>

PHP Code:


$simpleXML = new SimpleXMLElement('path/to/xmlfile.xml', 0, true);
$simpleXML->addChild('element2', 'innerText');
$simpleXML->asXML('path/to/xmlfile.xml');

Code:

<?xml version="1.0"?>
<body>
	<element>text</element>
       <element2>innerText</element2>
</body>
