我如何获得学校标记下的所有学校记录？我试过了，但它没有用。 $ eachListing-＆GT;以社区＆GT; Schools-＆GT;儿童（＆＃34;公共＆＃34;，TRUE）;

Answer 1

这里应该是某个地方的xmlns：commons =“...”属性。该属性的值是实际的命名空间，'common'前缀只是它的别名。使用命名空间在应用程序中定义变量或常量并使用它，而不是别名/前缀。

const XMLNS_COMMON = 'http://rets.org/xsd/RETSCommons'; // the value from the xmlns:common attribute?
$eachListing->Community->Schools->children(XMLNS_COMMON);

可以在文档中的每个节点上更改别名/前缀，这不是必需的。不要以你的逻辑为基础。

对于不在文档元素名称空间中的任何节点，可能需要执行此操作。

$nodes = $eachListing
  ->Community
  ->children(XMLNS_COMMON)->Schools
  ->children(XMLNS_COMMON);

$ Xml-＆gt; children（）不使用：commons标记
