XML and PHP 3

[Anon]

Combined two questions

I have a form that submits data 1 entry per line:

data 1
data 2
data 3

(the data can be anything or any length, and any ammount of lines, but they are always different lines separating data..

So I guess I could split them appart at "\n" right?

Now since there could be 1 line, or 10 lines, what is the quickest way to do that?

I was thinking of using:

code:

list ($item1, $item2) = split ('[\n.-]', $formdata);

Two things I don't know.

1. How can it be done so that it can accept more than 2 items?

2. Is "[\n.-]" correct?

The second question is. That data is saved in an XML file such as:

quote:

<xml>
<content>
<data>item 1</data>
<data>item 2</data>
</content>
<content2>
<data>item 1</data>
<data>item 2</data>
</content2>
</xml>

now how could I extract the data from the xml file? so that it could be put back in the form?

Does anyone know of a simple PHP3 routine that would basically break up content and content2, then breakup each "data"?

I know once it is extracted, I could use the following to put it back in the form:

code:

$data = "$item1\n$item2";

but how do I get it out of the XML file to do so?

BTW: Currently using PHP3 not PHP4, since that is what I found works best when I use PHP on my own box., PHP4 was causing nothing but errors. Besides, it's not going to be a huge script, just a simple script, thus not worth the time and hassle upgrading at this point.
