解析SOAP响应 [英] Parsing SOAP response
问题描述
从我的控制器调用网络服务:
Calling a web service from my controller:
$client = new \SoapClient("http://.../webservice/NAME_OF_PAGE.asmx?WSDL");
$result = $client->EstadoHabitacionesFechas();
我明白了:

我该如何解析和使用这些数据?
How can I parse this data and use it?
推荐答案
您不清楚使用"是什么，但您显然需要某种形式的XML解析/搜索.
You don't make very clear what "use" is, but you clearly need some form of XML parsing/search.
例如，尝试xml加载该字符串，然后var_dump结果.简单地列举各种属性应该可以为您显示机会.
For example, try xml-loading that string and var_dump the result. Simply enumerating the various properties should show you the opportunities.
稍后，您可以尝试 XPath搜索和更高级的技巧" "以加快工作速度.
Later on, you might try XPath search and more advanced "tricks" to speed up the work.
// Remove namespaces
$xml = str_replace(array("diffgr:","msdata:"),'', $xml);
// Wrap into root element to make it standard XML
$xml = "<package>".$xml."</package>";
// Parse with SimpleXML - probably there're much better ways
$data = simplexml_load_string($xml);
$rooms = $data->package->diffgram->DocumentElement->TablaEstadoHabitacion;
print "We have " . count($rooms) . " rooms: \n";
foreach($rooms as $i => $room)
{
print "Room {$i}: id={$room['id']} (official id: {$room->IdHabitacion}\n";
print "Entrada {$room->FechaEntrada}, salida {$room->FechaSalida}\n...\n";
}
您可以使用多个解析器，这是一个快速而又肮脏的解析器.
There are several parsers you can use, this is a quick and dirty one.

注意:对于非常大的XML数据集，我发现foreach是最好的.
Note: for very large XML data sets, I've found out that foreach is best.
对于大型数据集，这些数据集仅需要一些信息，而整个文件可能都不适合可用内存，则可能需要使用XMLParser或
And for large data sets where you only need a few information, and the whole file might not fit into available memory, you will probably want to use XMLParser, or XMLReader, and sift the whole file through the parser while keeping/manipulating (e.g. sending in a DB, or displaying to HTML) only the information you need.
虽然这通常不是一种好的做法，但是您可以在进入一个较长的XML解析循环之前关闭输出缓冲，并在输出后立即输出HTML，并不时刷新().这会将HTML外包给HTTP服务器，从而在PHP进程中占用更少的内存，但代价是压缩性能略逊一筹(如果您输出的HTML块大于40K，则差异可忽略不计)，并且响应性也相应地提高了(用户看到"某件事发生的速度更快，即使完成整个操作花费的时间更长一点.这种体验就是更快加载).
While this isn't in general good practice, you can turn output buffering off before entering a long XML parsing loop, outputting HTML as soon as you have it and flush()ing once in a while. This will outsource the HTML to the HTTP server, taking up less memory in the PHP process, at the expense of slightly inferior compression (if you output chunks of HTML of more than about 40K, the difference is negligible) and proportionally better responsivity (the user "sees" something happen faster, even if overall operation completion takes a little longer. The experience is that of a faster load).
