XML Base64 Binary Cotainer - How to decode, using PHP
Question
I need to decode a XML-Container which contains Base64-Binary-Data. The following code is just a little peace of the whole document but I think that you can see the format/schema. I don't know how to handle and base64_decode won't be the solution(?)
<container>
<header>
<Identifier>
<publicationId>2261000</publicationId>
</Identifier>
<ns2:Timestamp ns2:Id="body">
<ns2:Created>2014-06-06T16:00:03.177Z</ns2:Created></ns2:Timestamp>
</header>
<body>
<binary type="base64BinaryDatex2" id="B1">H4sIAAAAAAAAAOzdy5IbR5Yu6vl5ClgNdg+OOeT3i7Za23AlVSQlGckuHquZR4RHIoxIgBYASi3O

Before you can use base64_decode you need to pull out base64 encoded string out of XML:
// Load XML from $xml variable
$doc = new DOMDocument();
$doc->loadXML($xml);
// Now pull out <binary> elements with XPath
$xpath = new DOMXPath($doc);
$list = $xpath->query("//binary");
// Now go through each base64 string and decode
$decoded = array();
foreach ($list as $binary)
{
$decoded[] = base64_decode($binary->nodeValue);
}
Array $decoded will contain all decoded binary strings from your document
