xml_parser_create_ns
If you have multiple entries with the same key, exchange the lower part of the earlier mentioned script by this and it should solve the problem:
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\']]';
eval('$tmp = '.$php_stmt.';');
if (isset($tmp)) {
if (!is_array($tmp))
eval($php_stmt . ' = array( 0 => $tmp);');
eval($php_stmt . '[] = $xml_elem[\'value\'];');
} else
eval($php_stmt . ' = $xml_elem[\'value\'];');
}
xml_parser_create
(PHP 4, PHP 5)
xml_parser_create — Crea un parser XML
Descrizione
resource xml_parser_create
([ string $codifica
] )
La funzione xml_parser_create() crea un nuovo parser XML e restituisce un handle da utilizzarsi con le altre funzioni XML.
Il parametro opzionale codifica indica la codifica dei caratteri in input ed output per il PHP 4. A partire dal PHP 5, la codifica dell'input è determinata automaticamente, pertanto il parametro codifica indica solo dal codifica dell'output. In PHP 4, la codifica di default dell'output è la medesima utilizzata dall'input. Se si indica una stringa vuota, il parser tenta di inviduare la codifica utilizzata per il documento guardando l'intestazione dello stesso. In PHP 5.0.0 a 5.0.1, il set di caratteri di default è l' ISO-8859-1, mentre in PHP 5.0.2 e successivi è UTF-8. Le codifiche supportate sono "ISO-8859-1", "UTF-8" e "US-ASCII".

The above script doesnt parse very well for large (over 1000 tags) xml files because the foreach() uses a lot of memory. To solve the problem, replace foreach() with a for(), since for loops do not use near as much memory as the foreach. All in all though, very handy script

In PHP 5, when including in your xml file the definition '<?xml version="1.0" encoding="ISO-8859-1" ?>', I'd also recommend adding the option below:
xml_parser_set_option($xml_parser,XML_OPTION_TARGET_ENCODING, "ISO-8859-1").
It works fine!
If your enconding is 'UTF-8', just replace 'ISO-8859-1'.

I'd also recommend adding the option below
xml_parser_set_option($parser,XML_OPTION_SKIP_WHITE,1);

Actually, the XML parser DOES support more encodings.
The trick is to call $parser = xml_parser_create("");
I learned this trick from

The above "XML to array" code does not work properly if you have several tags on the same level and with the same name, example:
<currenterrors>
<error>
<description>This is a real error...</description>
</error>
<error>
<description>This is a second error...</description>
</error>
<error>
<description>Lots of errors today...</description>
</error>
<error>
<description>This is the last error...</description>
</error>
</currenterrors>
It will then only display the first <error>-tag.
In this case you will need to number the tags automatically or maybe have several arrays for each new element.

xml_parser_create () on php5 sometimes detects the wrong input format for me -- for example, sometimes when i try to parse data that has been fetched from a databse by my script and that only contains a handful of special ISO-8859-1 characters, it seems to think the input was something else and xml_parse() chokes on things like umlauts.
the only reason i was able to figure out so far would be that -- unlike my data files -- the xml data generated by my script doesn't contain the <?xml [...] encoding="..." ?> definition. every data source with that definition seemed just fine; it's kinda odd that it worked *sometimes* without it *shrugs*.
no matter what the reason, using utf8_encode () on the string made it work, and prepending '<?xml version="1.0" encoding="ISO-8859-1" ?>' worked as well.
this problem shouldn't occur in php4, since there you would specify the input encoding along with the output encoding.

Even though I passed "UTF-8" as encoding type PHP (Version 4.3.3) did *not* treat the input file as UTF-8. The input file was missing the BOM header bytes (which may indeed be omitted, according to RFC3629...but things are a bit unclear there. The RFC seems to make mere recommendations concering the BOM header). If you want to sure that PHP treats an UTF-8 encoded file correctly, make sure that it begins with the corresponding 3 byte BOM header (0xEF 0xBB 0xBF)

To maintain compatibility between PHP4 and PHP5 you should always pass a string argument to this function. PHP4 autodetects the format of the input if you leave it out whereas PHP5 will assume the format to be ISO-8859-1 (and choke on the byte order marker of UTF-8 files).
Calling the function as <?php $res = xml_parser_create('') ?> will cause both versions of PHP to autodetect the format.

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>

<state2>
<name>Low State</name>
