XML

[MagicalDean]

This my sound like an odd question, but could I use PHP to edit parts of an XML file? What i want to do is to use XML to store 3 values, the options for a quiz. I then want some way of editing the invidual options by basically adding one to the value in the correct tag

<poll>
<option1>10</option1>
<option2>10</option1>
<option3>10</option1>
</poll>

Although that isn't correct XML, its what the thing would look like roughly. I have a system that currently does the same, but instead of one XML thingie, I have 3 txt files, each of which is edited when their option is selected in the poll

I hope that all makes sense, and any help is greatly apprechiated

Of course you can PHP to do that. However, your XML is flawed, the closing tags do not match the opening tags.

Have a look at the DOM_XML functions:

http://www.php.net/manual/en/ref.domxml.php

They can be easily used to load and edit an XML file. There are also valuable examples in the manual. Furthermore, if you have questions, just let us know.

Ok, cheers for that. I'll have a look once I get my computer up and running. If anyone else has any tips/advice/etc then please feel free to add it

Beside use DOM XML, you can use SimpleXML, here is the reference:

http://id2.php.net/manual/en/ref.simplexml.php

Make sure either domxml or simplexml exists in your php configuration.
If you are not sure about how to detect this, please make a php file just like this:
<?php
phpinfo();
?>
That script will list the whole config of your php. Search if there is any of domxml or simplexml. If that exists, means that you can use either one.
Hope that helps.
