【中文标题】如何使用 PHP 将 Simple XML 解释为 HTML？【英文标题】：How interpret Simple XML to HTML with PHP? 【发布时间】：2022-01-06 18:37:24 【问题描述】：我从服务器获得了简单 XML 的响应，但我只想获取我需要的页面数据并在 html 标记中显示这些数据。我该怎么做？
我的请求代码：
include "TopSdk.php";
date_default_timezone_set('Asia/Shanghai');
$c = new TopClient;
$c->appkey = '*******';
$c->secretKey = '***************';
$req = new AliexpressAffiliateProductQueryRequest;
$req->setAppSignature("1111");
$req->setFields("sale_price");
$req->setKeywords("car");
$req->setMaxSalePrice(300);
$req->setMinSalePrice(150);
$req->setPageNo(1);
$req->setPageSize(2);
$req->setSort("SALE_PRICE_ASC");
$req->setTargetCurrency("USD");
$req->setTargetLanguage("en");
$req->setTrackingId("trackID");
echo "<pre>";
var_dump($c->execute($req));
echo "</pre>";

我需要例如 olny 字符串：Title["product_title"]、Price["sale_price"] 和 TrackID["promotion_link"]，我怎样才能得到它？并仅在网页上显示此数据：
<h1>Title</h1>
<h2>Price</h2>
<a href>TrackID</a>
谢谢！
【问题讨论】：
与其尝试解释SimpleXMLElement 的var_dump() 输出（这并不总是非常清楚，尤其是没有缩进），为什么不参考API 文档了解响应格式？那肯定会清楚很多。甚至像echo $c->execute($req)->asXML(); 这样的东西可能更容易理解
嗨！默认值为 XML。该值可以设置为 XML 或 JSON
谢谢，菲尔！您的建议“echo $c->execute($req)->asXML();”帮帮我！
【参考方案1】：
试试这个。
$content = "xml content";
$xml = new \SimpleXMLElement($content);
foreach($xml->resp_result->result->products->product as $product)
echo "<h1>" . $product->product_title . "</h1>";
echo "<h2>" . $product->sale_price . "</h2>";
echo "<a href>" . $product->promotion_link . "</a>";
如果没有运行或出错，请检查 php-xml 模块是否已安装。
【讨论】：
嗨！如果我将此代码添加到我的请求中（我的请求代码 + 您的代码），我会收到“此网站上的严重错误”。我检查了 php-xml 模块是否已安装“php-xml-8.0.13-1.el7.remi.x86_64 已安装且最新版本” 检查/var/log/httpd 中的error_log 文件，最后的记录显示代码的哪一部分出错了，什么错误。这可以帮助我们解决问题。如果你能在这里发帖，我很感激！ [2021 年 11 月 30 日星期二 15:49:40.722498] [php:error] [pid 17643] [client ip-adress:34498] PHP 致命错误：未捕获的异常：字符串无法解析为 XML在 /home/admin/web/domain/public_html/wp-content/plugins/insert-php/includes/shortcodes/shortcode-php.php(52) : eval()'d 代码：22\n堆栈跟踪：\n# 0 /home/admin/web/domain/public_html/wp-content/plugins/insert-php/includes/shortcodes/shortcode-php.php(52) : eval()'d 代码(22): SimpleXMLElement->__construct( )\n#1 /home/admin/web/domain/public_html/wp-content/plugins/insert-php/includes/shortcodes/shortcode-php.php(52): eval()\n#2 ... 问题是xml结构，可能是它没有所有必要的属性。你有办法发布这个 XML 内容吗？ 所有我得到的都显示在“SXML 中的服务器响应”中。在后端，我使用“我的请求代码”，网页上的响应可视化是“SXML 中的服务器响应”。也许你是对的……也许反应比必须的要短。我想要的只是使用我拥有的这个响应数据，并且只显示我想要的 html 标签......以上是关于如何使用 PHP 将 Simple XML 解释为 HTML？的主要内容，如果未能解决你的问题，请参考以下文章
