php XML DOM translates special chars to &#xYY;

Question 1

I send this with AJAX POST:

<li><ul class   "zone zCentral ui-sortable"><li><ul class="region rCol3 ui-sortable"><li class="" style=""><div><span class="tc tc_video">574081</span> <span>video: 'Mundo.Hoy': ¿Dónde habré olvidado... mi memoria?</span></div></li></ul></li></ul></li>

I do this to create XML:

        header('Content-type: text/html; charset=utf-8');       
    if(isset($_POST) && isset($_POST['data']))
    {           
        $data = '<ul id="zone_container" class="ui-sortable">';
        $data .= $_POST['data'];
        $data .= '</ul>';                           

        $dom = new DOMDocument('1.0', 'utf-8');
        $dom->loadXML($data);

        echo $dom->saveXML();                       
        exit();
    }

and i get this:

<?xml version="1.0"?>
<ul id="zone_container" class="ui-sortable">
    <li><ul class="zone zCentral ui-sortable"><li><ul class="region rCol3         ui-sortable"><li class="" style=""><div><span class="tc tc_video">574081</span>     <span>video: 'Mundo.Hoy': &#xBF;D&#xF3;nde habr&#xE9; olvidado... mi memoria?</span></div>    </li></ul></li></ul></li></ul>

¿Dónde habré olvidado... mi memoria?

translates to:

&#xBF;D&#xF3;nde habr&#xE9 ; olvidado... mi memoria?

I need original chars in the XML, these are utf-8 valid and i don't know the reason for this encode :(

Question 2

The easiest way to fix this is to set the encoding type after you have loaded the XML:

$dom = new DOMDocument();
$dom->loadXML($data);
$dom->encoding = 'utf-8';

echo $dom->saveXML();                       
exit();

You can also fix it by putting an XML declaration at the beginning of your data:

$data = '<?xml version="1.0" encoding="utf-8"?>' . $data;
$dom = new DOMDocument();
$dom->loadXML($data);

echo $dom->saveXML();
exit();

Question 3

On some installations, there is a bug in pecl. Find this line;

exec $PHP -C -n -q $INCARG -d date.timezone=UTC -d output_buffering=1 -d variables_order=EGPCS -d safe_mode=0 -d register_argc_argv="On" $INCDIR/peclcmd.php "$@"

remove the -n

If you want to script it, try:

sed -i "$ s|-n||g" /usr/bin/pecl

Question 4

Ok, let’s try this complete example of use:

function CatRemove($myXML, $id) {
    $xmlDoc = new DOMDocument();
    $xmlDoc->load($myXML);
    $xpath = new DOMXpath($xmlDoc);
    $nodeList = $xpath->query('//category[@id="'.(int)$id.'"]');
    if ($nodeList->length) {
        $node = $nodeList->item(0);
        $node->parentNode->removeChild($node);
    }
    $xmlDoc->save($myXML);
}

// test data
$xml = <<<XML
<?xml version="1.0"?>
<details>
 <person>name</person>
 <data1>some data</data1>
 <data2>some data</data2>
 <data3>some data</data3>
 <category id="0">
  <categoryName>Cat 1</categoryName>
  <categorydata1>some data</categorydata1>
 </category>
 <category id="1">
  <categoryName>Cat 2</categoryName>
  <categorydata1>some data</categorydata1>
  <categorydata2>some data</categorydata2>
  <categorydata3>some data</categorydata3>
  <categorydata4>some data</categorydata4>
 </category>
</details>
XML;
// write test data into file
file_put_contents('untitled.xml', $xml);
// remove category node with the id=1
CatRemove('untitled.xml', 1);
// dump file content
echo '<pre>', htmlspecialchars(file_get_contents('untitled.xml')), '</pre>';

Question 5

You need to import any node to append it to another document:

$departmentArray->item($i)->appendChild( $doc->importNode( $employee, true ) );

Question 6

If anyone should be interested, i have provided the correct answer:

$soapUrl = "http://privpakservices.schenker.nu/package/package_1.3/packageservices.asmx?op=SearchCollectionPoint";

$xml_post_string = '<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><SearchCollectionPoint xmlns="http://privpakservices.schenker.nu/"><customerID>XXX</customerID><key>XXXXXX-XXXXXX</key><serviceID></serviceID><paramID>0</paramID><address>RiksvŠgen 5</address><postcode>59018</postcode><city>Mantorp</city><maxhits>10</maxhits></SearchCollectionPoint></soap12:Body></soap12:Envelope>';

$headers = array(
"POST /package/package_1.3/packageservices.asmx HTTP/1.1",
"Host: privpakservices.schenker.nu",
"Content-Type: application/soap+xml; charset=utf-8",
"Content-Length: ".strlen($xml_post_string)
); 

$url = $soapUrl;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($ch); 
curl_close($ch);

$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);

$parser = simplexml_load_string($response2);
