我想做的是将<county>
嵌套在<counties>
中,如下=>$county_population = (string) $dataset->phoneInfo->ratecenter->counties->county->attributes()->populationIn2006;
我想获取标签populationIn2006
中的数据
如何做到这一点?
请帮忙!非常感谢您花时间研究此事。
命令已关闭,但缺少operatingCompany
节点,并且"ratecenter"拼写错误(需要大写C)。
您发布的XML也是无效的,因为它缺少结束</operatingCompany>
标记,但我认为这是一个复制/粘贴错误。
$county_population = (string) $dataset->phoneInfo->operatingCompany->rateCenter->counties->county->attributes()->populationIn2006;
