Simple XML editing

[el22]

I have an xml file that is loaded by a Flash animation -- but thats not the point.

I want to load the xml (actually, they are 4 XMLs) display everything in many form fields and when submitting the form updating every xml. Sort of a simple admin backend.

Each xml looks something like this:

<?xml version="1.0"?>
	<news>
		<item title="Title 1" text="Long text 1" url="1.htm" />
		<item title="Title 2" text="Long text 2" url="2.htm" />
	</news>

Every xml has only two items like that.

I would like to get them in an array like

$xml1[0][title];
to get "Title 1"

$xml1[1][text];
to get "Long text 2"

(etc.)

The rest of the system is not a problem, i just need to put all the info inside the xmls in arrays.

Thanks in advance guys! 🙂

Thanks.

However, i've been trying to change an example (no.2).

What i have so far is:

<?php

class AminoAcid {
    var $title;
    var $text;
    var $url;

function AminoAcid ($aa) {
    foreach ($aa as $k=>$v)
        $this->$k = $aa[$k];
}
}

function readDatabase($filename) {
    // read the xml database of aminoacids
    $data = implode("",file($filename));
    $parser = xml_parser_create();
    xml_parser_set_option($parser,XML_OPTION_CASE_FOLDING,0);
    xml_parser_set_option($parser,XML_OPTION_SKIP_WHITE,1);
    xml_parse_into_struct($parser,$data,$values,$tags);
    xml_parser_free($parser);

// loop through the structures
foreach ($tags as $key=>$val) {
    if ($key == "item") {
        $molranges = $val;
        // each contiguous pair of array entries are the 
        // lower and upper range for each molecule definition
        for ($i=0; $i < count($molranges); $i+=2) {
                $offset = $molranges[$i] + 1;
            $len = $molranges[$i + 1] - $offset;
            $tdb[] = parseMol(array_slice($values, $offset, $len));
        }
    } else {
        continue;
    }
}
return $tdb;
}

function parseMol($mvalues) {
    for ($i=0; $i < count($mvalues); $i++)
        $mol[$mvalues[$i]["tag"]] = $mvalues[$i]["value"];
    return new AminoAcid($mol);
}

$eng1 = readDatabase("../eng/news.xml");
echo "** Database:\n";
print_r($eng1);  //this is just to test if the array gets formed ok, then i will remove it

?>

But... php gives me the following error:

Warning: Invalid argument supplied for foreach() in ******.php on line 9
