Here are the codes:

$doc = new DomDocument('1.0');
// create root node
$root = $doc->createElement('root');
$root = $doc->appendChild($root);
$signed_values = array('a' => 'eee', 'b' => 'sd', 'c' => 'df');
// process one row at a time
foreach ($signed_values as $key => $val) {
    // add node for each row
    $occ = $doc->createElement('error');
    $occ = $root->appendChild($occ);
    // add a child node for each field
    foreach ($signed_values as $fieldname => $fieldvalue) {
        $child = $doc->createElement($fieldname);
        $child = $occ->appendChild($child);
        $value = $doc->createTextNode($fieldvalue);
        $value = $child->appendChild($value);
    }
}
// get completed xml document
$xml_string = $doc->saveXML() ;
echo $xml_string;

If I print it in the browser I don't get nice XML structure like

<xml> n tab <child> etc.

I just get

<xml><child>ee</child></xml>

And I want to be utf-8 How is this all possible to do?

You can try to do this:

...
// get completed xml document
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;
$xml_string = $doc->saveXML();
echo $xml_string;

You can make set these parameter right after you've created the DOMDocument as well:

$doc = new DomDocument('1.0');
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;

That's probably more concise. Output in both cases is (Demo):

<?xml version="1.0"?>
<root>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
</root>

I'm not aware how to change the indentation character(s) with DOMDocument. You could post-process the XML with a line-by-line regular-expression based replacing (e.g. with preg_replace):

$xml_string = preg_replace('/(?:^|G)  /um', "t", $xml_string);

Alternatively, there is the tidy extension with tidy_repair_string which can pretty print XML data as well. It's possible to specify indentation levels with it, however tidy will never output tabs.

tidy_repair_string($xml_string, ['input-xml'=> 1, 'indent' => 1, 'wrap' => 0]);

Using the code above failed for me and it was not due to the comma as I commented. I found that, using curl, I was able to retrieve the xml file.

$c=curl_init('http://www.alef.ir/rssdx.gmyefy,ggeltshmci.62ay2x.y.xml');
curl_setopt( $c, CURLOPT_USERAGENT,'nginx-curl-blahblahblah' );
curl_setopt( $c, CURLOPT_RETURNTRANSFER, true );
$r=curl_exec( $c );
curl_close( $c );

$doc = new DOMDocument();
$doc->loadxml($r);
$arrFeeds = array();

foreach ($doc->getElementsByTagName('item') as $node) {

    $title=$node->getElementsByTagName('title')->item(0)->nodeValue;
    $title=strip_tags($title);
    $link=$node->getElementsByTagName('link')->item(0)->nodeValue;

}

By default, DOMDocument::$preserveWhiteSpace is true. Try setting it to false on the document in question, then calling saveXML again. This may have side effects should any whitespace inside the document actually matter. You should also make sure that DOMDocument::$formatOutput is false.

As said by Gordon, though, there is no logical reason whatsoever for the whitespace restriction. Though seriously, if you don't want any whitespace in there whatsoever, just make sure any CR/LF characters that you want to keep are entity-encoded and then $nonewlines = preg_replace("/[rn]/", '', $xml) to yank out the newlines that might remain after turning off Preserve and Format. But again, that's silly.

Using recursion, you can create a brand new document based on the input, solving all your points at once:

Code

<?php

$input = file_get_contents('http://www.fluffyduck.com.au/sampleXML.xml');
$inputDoc = new DOMDocument();
$inputDoc->loadXML($input);

$outputDoc = new DOMDocument("1.0", "utf-8");
$outputDoc->appendChild($outputDoc->createElement("root"));

function ConvertUserToItem($outputDoc, $inputNode, $outputNode)
{
    if ($inputNode->hasChildNodes())
    {
        foreach ($inputNode->childNodes as $inputChild)
        {
            if (strtolower($inputChild->nodeName) == "user")
            {
                $outputChild = $outputDoc->createElement("item");
                $outputNode->appendChild($outputChild);
                // read input attributes and convert them to nodes
                if ($inputChild->hasAttributes())
                {
                    $outputContent = $outputDoc->createElement("content");
                    foreach ($inputChild->attributes as $attribute)
                    {
                        if (strtolower($attribute->name) != "id")
                        {
                            $outputContent->appendChild($outputDoc->createElement($attribute->name, $attribute->value));
                        }
                        else
                        {
                            $outputChild->setAttribute($attribute->name, $attribute->value);
                        }
                    }               
                    $outputChild->appendChild($outputContent);
                }
                // recursive call
                ConvertUserToItem($outputDoc, $inputChild, $outputChild);
            }
        }
    }
}

ConvertUserToItem($outputDoc, $inputDoc->documentElement, $outputDoc->documentElement);

header("Content-Type: text/xml; charset=" . $outputDoc->encoding);
echo $outputDoc->saveXML();
?>

Output

<?xml version="1.0" encoding="utf-8"?>
<root>
    <item id="41">
        <content>
            <username>bsmain</username>
            <firstname>Boss</firstname>
            <lastname>MyTest</lastname>
            <fullname>Test Name</fullname>
            <email>lalal@test.com</email>
            <logins>1964</logins>
            <lastseen>11/09/2012</lastseen>
        </content>
        <item id="61">
            <content>
                <username>underling</username>
                <firstname>Under</firstname>
                <lastname>MyTest</lastname>
                <fullname>Test Name</fullname>
                <email>lalal@test.com</email>
                <logins>4</logins>
                <lastseen>08/09/2009</lastseen>
            </content>
        </item>

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>RiksvÅ gen 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);
