Edit data from XML using PHP

I have the following XML file. I have managed to create a code that adds and removes data. However, I am not able or found anything helpful on how to edit the existing data. My goal is to let the user through a form to write the existing (let's say name) Ben and in another textbox the desired name and submit. I am able to create the form and parse the two vars. Thank you!

the xml

<?xml version="1.0" encoding="utf-8"?>
<messages>
    <message time="1248083538">
        <name>Ben</name>
        <email>Ben's Email</email>
        <msg>Bens message</msg>
    </message>
    <message time="1248083838">
        <name>John Smith</name>
        <email>[email protected]</email>
        <msg>Can you do this for me?</msg>
    </message>
</messages>

Don't "modify the XML" -- that implies that you're performing text-operations on it. Possibly using some messy regular expressions and bunch of evil string-functions. If you're not doing that, forgive me.

What you want to do is to:

  • Read the XML and create a data structure.
  • Operate on that data structure.
  • Transform your modified data structure back into XML.

Lucky for you, SimpleXML, makes doing exactly that nice and easy.
