thought I'd share this small piece of PHP code that prepares a proper array from XML Data
(uses xml_parse_into_struct to get a raw array)
features : 1) can easily adjust to multiple levels 2) simple.
<code>
$file = "data.xml";
$xml_parser = xml_parser_create();
if (!($fp = fopen($file, "r"))) {
die("could not open XML input");
}
$data = fread($fp, filesize($file));
fclose($fp);
xml_parse_into_struct($xml_parser, $data, $vals, $index);
xml_parser_free($xml_parser);
$params = array();
$level = array();
foreach ($vals as $xml_elem) {
if ($xml_elem['type'] == 'open') {
if (array_key_exists('attributes',$xml_elem)) {
list($level[$xml_elem['level']],$extra) =
array_values($xml_elem['attributes']);
} else {
$level[$xml_elem['level']] = $xml_elem['tag'];
}
}
if ($xml_elem['type'] == 'complete') {
$start_level = 1;
$php_stmt = '$params';
while($start_level < $xml_elem['level']) {
$php_stmt .= '[$level['.$start_level.']]';
$start_level++;
}
$php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
eval($php_stmt);
}
}
echo "<pre>";
print_r ($params);
echo "</pre>";
</code>
Example :
I/P XML ...
<country id="ZZ">
<name>My Land</name>
<location>15E</location>
<area>40000</area>
<state1>
<name>Hi State</name>
<area>1000</area>
<population>2000</population>
<city1>
<location>13E</location>
<population>500</population>
<area>500</area>
</city1>
<city2>
<location>13E</location>
<population>500</population>
<area>5000</area>
</city2>
</state1>
<state2>
<name>Low State</name>
<area>3000</area>
<population>20000</population>
<city1>
<location>15E</location>
<population>5000</population>
<area>1500</area>
</city1>
</state2>
</country>
