Question

我试图将所有<name></name>数据从下面的xml树中拉出来。我还在下面包含了我的php，这是行不通的。在此先感谢您的帮助

以下是XML的一部分，可以在url（它是一个很长的xml树）中找到：

https://api.morningstar.com/v2/service/mf/oi397kxo7gb3o1c5/ticker/qyld?accesscode=ymjfk0fok83k7xg7kxse7tuzm7x0h3wp

这是PHP

<?php
$url = 
"https://api.morningstar.com/v2/service/mf/oi397kxo7gb3o1c5/ticker/qyld?accesscode=ymjfk0fok83k7xg7kxse7tuzm7x0h3wp";

$xml = simplexml_load_file($url);

$data = ($xml->data->api->T10H-Holdings->HoldingDetail->{'Name'}-
>__tostring());

echo($data);
?>

Answer 1

是的，T10H-Holdings不能按原样使用。您可以使用大括号和引号进行换行。

然后要获取<Name>的所有值，您可以使用foreach()循环：

$url = "https://api.morningstar.com/v2/service/mf/oi397kxo7gb3o1c5/ticker/qyld?accesscode=ymjfk0fok83k7xg7kxse7tuzm7x0h3wp";

$xml = simplexml_load_file($url);
foreach ($xml->data->api->{"T10H-Holdings"}->HoldingDetail as $holding) {
    echo (string)$holding->Name . "\n" ;
}

输出：

Apple Inc
Amazon.com Inc
Microsoft Corp
Facebook Inc A
Alphabet Inc C
NASDAQ-100 Mar. 16, 2018 Call 6825
Alphabet Inc A
Intel Corp
Cisco Systems Inc
Comcast Corp Class A

但是，如果你只想获得第一个，你可以使用：

echo $xml->data->api->{"T10H-Holdings"}->HoldingDetail->Name->__toString() ;

输出：

Apple Inc

使用XML API中的PHP访问特定数据点
