但我在获取命名空间子标记时遇到问题。当我只返回 1 时一切正常，但现在我正在拉多个，我真的很难得到一个好的对象数组。

不幸的是，我已经编写了这么多不同形式的函数，我什至不确定现在哪一个最接近。

示例 1：

public function parseMultipleEntriesIntoAnObject($xml) {
        $z = new XMLReader();
        $z->xml($xml);
        //while ($z->read() && $z->name !== 'entry');
        // <content>
        // m:properties
        // d:<property_name
        $results = [];
        $key = "";
        while( $z->read() ) {
            //print($z->name);
            if ($z->nodeType == XMLReader::ELEMENT && $z->name === 'entry') {
                $r = new \stdClass;
                //dd("Yeup");
                while ($z->read()) {
                    // reached the </entry>. skip to next                   
                    if ($z->nodeType === XMLReader::END_ELEMENT && $z->name === 'entry') {
                        $results[] = $r;
                        $z->next('entry');
                        $r = new \stdClass;
                    }
                    // this may mess up on nested elements. Oh well.
                    if ($z->nodeType === XMLReader::ELEMENT) {
                        $key = $z->name;
                    }
                    if ($z->nodeType === XMLReader::TEXT) {
                        //echo "$key = $z->value <br/>";
                        $r->{$key} = $z->value;
                    }   
                }
            }
        }
        $z->close();

        return $results;
    }

示例 2 和 3：

private function getXMLEntries($xml) {
        $resultsArray = [];
        $str = trim(preg_replace('/\s\s+/', '', $xml));
        $z = new XMLreader;
        $doc = new \DOMDocument;

        $z->xml($str);
        $props = [];
        while ($z->read() && $z->name !== 'entry');
        while ($z->name === 'entry') {
            $x = simplexml_import_dom($doc->importNode($z->expand(), true));
            var_dump($x->content);
            $resultsArray[] = $x;
            //$resultsArray[] = $z->expand();
            $z->next('entry');
        }
        return $resultsArray;
    }
    private function processXMLProperties($xml) {
        $str = trim(preg_replace('/\s\s+/', '', $xml));
        $z = new XMLreader;
        $z->xml($str);
        $props = [];
        while ($z->read() && $z->name !== 'm:properties');
        $key = "";
        while ($z->read()) {
            if ($z->nodeType === XMLReader::ELEMENT) {
                $key = $z->name;
                $z->read();
            }
            if ($z->nodeType === XMLReader::TEXT) {
                $props[$key] = $z->value;
            }
        } return $props; }

希望你能看到我想要做什么。如果重要的话，这可以通过使用 Guzzle 的 Stream 来实现。基本上我需要一个对象数组，其中每个对象都包含的各种属性，理想情况下没有它们的 d: 前缀。

请注意，根据我附加到查询中的内容，任何相关的

感谢您的帮助！

使用 Xpath。

d 命名空间未在 XML 字符串中定义，但在将 xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" 添加到 <feed> 标记时，以下工作：

【讨论】：

我需要测试；我无权访问 API 生成，所以我必须看看是否可以将 NS 信息动态插入到输入流中。如果可以的话，我很乐意将其标记为已回答。如果我做不到，你们有其他解决方案吗？
我不知道在 PHP 中访问命名空间标签属性的另一种方法。
没关系，我将流读入一个数组，然后将属性preg in....除非我不必； API 已更新为包含命名空间！ ;) 感谢您的帮助！
这个答案虽然侧重于一次获取所有 d 命名空间的标签及其属性 (//m:properties/d:*)。您的实现可能需要一种不同的方法，例如遍历 s，然后在每个节点上使用直接 xpath 选择器，即 m:properties/d:* 不带前导 //。
