php simplexml 在读取名称中包含“列 - :"的属性时出现问题 [英] php simplexml issue in reading an attribute that has a 'column - : ' in its name

问题描述

我一直在尝试读取一个包含:"的 xml 属性，但我遇到了问题......特别是yweather:condition"

I have been trying to read an xml attribute that has a " : " in it, but I'm having trouble...specifically "yweather:condition"

这是我的代码:

 if ($xml = simplexml_load_file("http://weather.yahooapis.com/forecastrss?p=LEXX0003&u=c")) {
    $namespacesMeta = $xml->getNamespaces(true);
    $yweather = $xml->children($namespacesMeta['yweather']);
    $docMeta = $yweather->{'condition'};
    var_dump($docMeta);
}

我在 stackoverflow 上阅读了另一个线程后到达这里，但结果与我预期的不一样，我得到以下信息:

i got here after reading off another thread on stackoverflow, but the result is not as I expected, I get the following:

对象(SimpleXMLElement)[3]

object(SimpleXMLElement)[3]

您可以查看上面的链接以查看完整的 xml，

You can check the above link to see the full xml,

我想读取yweather:condition"中的属性我知道如何访问和读取 XML 的其他部分，但是这个部分很棘手……我也尝试过 getAttributes() 但它没有用

I want to read the attributes in "yweather:condition" I know how to access and read the other parts of the XML, but this one is being tricky...I also tried getAttributes() and it did not work

谢谢

推荐答案

$docMetaAttributes = $docMeta->attributes(); 

或

$docMetaAttributes = $docMeta->attributes($namespacesMeta['yweather']);  

用于 yweather 命名空间中的命名空间属性

for namespaced attributes in the yweather namespace
