Question

我需要解码包含Base64-Binary-Data的XML-Container。以下代码只是整个文档的一点点安静，但我认为您可以看到格式/架构。我不知道如何处理和base64_decode不会成为解决方案（？）

在使用base64_decode之前，您需要从XML中提取base64编码的字符串：

// 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 $ decoding将包含文档中所有已解码的二进制字符串
