php - 在 PHP 中读取 XML 文件时需要帮助

问题描述

我正在尝试使用 simpleXML 从 PHP 中的 XML 文件中获取数据，但是当我尝试读取它时，我不断收到错误“simplexml 试图获取非对象的属性”。这是我正在使用的 XML 文件：

例如，我尝试使用 $cnpj = $xmldata->cteProc->CTe->infCte->emit 获取标签下方包围的 CNPJ 的值，但没有成功。抱歉，我对 PHP 有点陌生，不知道哪里出错了，谢谢

标签： phpxml

解决方案

simplexml_load_[string|file]()将消耗包装标签，在你的情况下是cteProc标签。

这意味着您无需查看该对象内部即可访问其中的其他对象。

要到达CNPJ，它看起来像：

$cnpj = $xmldata->CTe->infCte->emit->CNPJ;
