I have played with XML::Simple recently. It seems to lend itself to simple XML files (thus the name). My recomendation on this is is that if you have very simple files (like config files) then this is your go. When the files have nested attributes, it is better to look upwards, like Parse in stream mode. Your xml file looks like this (with code tags)
<greeting>
Hi
</greeting>
<greeting>
Hello
</greeting>
to
<greeting>
Hi
</greeting>
<greeting>
Goodbye
</greeting>
Since this is a simple (almost config like) task, I would go with simple.
With something like this:
<greeting>
How are you?
<positive>
<response>
Fine
</response>
<response>
OK
</response>
<reponse>
Good
</reponse>
</positive>
<negative>
<response>
Bad
</reponse>
<response>
Not well
</reponse>
<negative>
</greeting>
<greeting>
If this were the case, you would need something more complex than Simple provides. If you learn to use the most sophisicated method to begin with, it can scale up with you as your assignments (er, tasks, projects).
