<FlightSegment DepartureDateTime="2016-09-20T06:05:00" ArrivalDateTime="2016-09-20T08:05:00" FlightNumber="716" ResBookDesigCode="N">
    <FlightDuration>2016-09-14T02:00:00</FlightDuration>

    </BookingClassAvails>
</FlightSegment>

有两个航段。我们在此代码中没有任何标识符，所以，

如何按块分割此代码以使用第一个<FlightSegment>块中的属性？
此外，我需要计算<FlightSegments>。

请帮助！）

您可以使用此函数将XML节点转换为（嵌套）数组：

function domToArray($node) {
    $arr = [];
    // Add all attributes of this node as key/values:
    foreach ($node->attributes as $attribute) {
        $arr[$attribute->nodeName] = $attribute->nodeValue;
    }
    // Iterate through the child nodes
    foreach ($node->childNodes as $child) {
        if ($child->nodeType === XML_TEXT_NODE) {
            // Assign the text content to a "value" key
            if (trim($child->textContent)!== '') {
                $arr['value'] = $child->textContent;
            }
        } else if ($child->nodeType === XML_ELEMENT_NODE) {
            // Create key/value pairs for child nodes, using recursion.
            // If the children are repeated elements, then build
            // an indexed array, otherwise an associative array.
            if (preg_replace("/y$/", "ie", $child->nodeName) ."s" === $node->nodeName) {
                $arr[] = domToArray($child);
            } else {
                $arr[$child->nodeName] = domToArray($child);
            }
        }
    }
    return $arr;
}

首先必须创建一个DOMDocument并将XML字符串读入其中。请注意，您提供的XML片段需要包含在一个单独的元素中，我故意称之为FlightSegments - FlightSegment的倍数，其中有2个：

$doc = new DOMDocument();
$doc->loadXML("<FlightSegments>$xml</FlightSegments>");

完成后，您可以调用我上面提到的功能：

// Convert XML to nested array:
$flightSegments = domToArray($doc->documentElement);

以下是您可以从该阵列获得的一些输出：

// Number of FlightSegments:
echo "Number of FlightSegment elements: " . count($flightSegments) . "<br>";

echo "DepartureDateTime of first FlightSegment: " . $flightSegments[0]['DepartureDateTime'] . "<br>";

echo "All information:<br>";

print_r ($flightSegments);

在eval.in上看到它。

使用您提供的示例XML，上述代码的输出将为：

我不确定您的问题是什么，因为在评论中您共享了成功遍历XML的代码。

请注意，您可以使用上面的函数将完整的XML转换为数组（我对函数进行了一次修正，以正确识别以“y”结尾的标记名称的复数形式。）

以下是在XML上调用它的方法：

$soap = domToArray($xmlDoc->documentElement);

$soap的内容将是（我将其截断）：

现在您可以编写如下代码：

$itineries = $soap['soap:Body']['SearchFlightResponse']['OTA_AirLowFareSearchRS']['PricedItineraries']; 
foreach ($itineries as $itinery) {
    // ... etc. Always array access.
}

现在你的函数从xml文档的最后一段创建了大量文件：

<?php

function domToArray($node) {
    $arr = [];
    // Add all attributes of this node as key/values:
    foreach ($node->attributes as $attribute) {
        $arr[$attribute->nodeName] = $attribute->nodeValue;
    }
    $useName = true;
    // Iterate through the child nodes
    foreach ($node->childNodes as $child) {
        if ($child->nodeType === XML_TEXT_NODE) {
            // Assign the text content to a "value" key
            if (trim($child->textContent)!== '') {
                $arr['value'] = $child->textContent;
            }
        } else if ($child->nodeType === XML_ELEMENT_NODE) {
            // Create key/value pairs for child nodes, using recursion.
            // If the children are repeated elements, then build
            // an indexed array, otherwise an associative array.
            if ($child->nodeName ."s" === $node->nodeName) {
                $arr[] = domToArray($child);
            } else {
                $arr[$child->nodeName] = domToArray($child);
            }
        }
    }
    return $arr;
}





$xmlDoc = new DOMDocument();
$xmlDoc->load("response.xml");
$soap = domToArray($xmlDoc->documentElement);
print_r($soap);

?>

在这里，您可以完全看到所有文档：response.xml

这里包含$soap：Array

你的决定是理想的：

// If the children are repeated elements, then build
// an indexed array, otherwise an associative array.

...但是当我尝试加载response.xml时，它并没有构建索引数组。它只是用最后一个FlightSegment构建了大量......
