无法从 simplexml 对象中提取数据

Question

我从以下位置获取一个 simplexml 对象：

$xml = simplexml_load_string($data);

如果我这样做dd($xml)我会在控制台中得到以下字符串：

SimpleXMLElement {#232
+"Data": SimpleXMLElement {#240}
+"Error": SimpleXMLElement {#241}
+"xmlData": "<root><row><FiscalCode>27221245</FiscalCode><CompanyName>Nume Companie SRL</CompanyName><LegalForm>SRL</LegalForm><RegistrationNumber>J40/111/2010</RegistrationNumber><DateOfIncorporation>2010-07-29</DateOfIncorporation><Status>functiune;</Status><ShareCapital>1.510000000000000e+005</ShareCapital><NACE>6201</NACE><NACE_Descr>Activităţi de realizare a soft-ului la comandă (software orientat client)</NACE_Descr><PrimaryActivityVersion>2</PrimaryActivityVersion><NumberOfemployees>20</NumberOfemployees><County>Municipiul Bucuresti</County><City>BUCURESTI SECTORUL 5</City><Street>DR.

}

提取财务代码的正确方法

我提到dd($xml->FiscalCode)什么也没返回。

也

dd($xml->root->row->FiscalCode);不起作用

原始 xml 是从外部链接获取的：

它看起来像这样：

<?xml version="1.0" encoding="utf-8"?>

我得到这样的链接：

$curl = curl_init();
curl_setopt_array($curl, Array(
CURLOPT_URL            => 'https://wsprokolekt.rocomp.ro/service.asmx/CompanyGeneralInformation?idUser=*****&CUI=******',
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_ENCODING       => 'UTF-8'
));
$data = curl_exec($curl);
$xml = simplexml_load_string($data);

谢谢你的时间！

Answer 1

首先，读取和解码 xmlData，然后获取 FiscalCode

$xml = simplexml_load_string($str);
$xml1 = simplexml_load_string(html_entity_decode($xml->xmlData));
echo $xml1->row->FiscalCode;
