请问各路大神,在XML节点 层次结构不确定的情况下,如何判断两个XML节点是否相同?
这里我们约定当节点存在子节点时,子节点的排列顺序不影响XML节点的判断。

例如有以下两个XML节点:
节点1:

<a>    <b><d>1</d></b>    <c>2</c></a>

节点2:
<a>    <c>2</c>    <b><d>1</d></b></a>

在我们现在的逻辑中,认为节点1和节点2是 相同的两个节点。

请问在PHP中有没有什么办法可以判断这两个节点是相同的呢?

谢谢!

$s =<<< XML<a>    <b><d>1</d></b>    <c>2</c></a><a>    <c>2</c>    <b><d>1</d></b></a>XML;$xml = simplexml_load_string($s);$t = $xml->xpath('///a');$t = array_map('objectToarray', $t);//print_r($t);var_dump($t[0] == $t[1]);function objectToArray($d) {   if (is_object($d)) {     $d = get_object_vars($d);   }  if (is_array($d)) {     return array_map(__FUNCTION__, $d);   } else {     return $d;   } }
bool(true)

T  T  多谢版主!一个很好的思路~

$s =<<< XML<a>    <b><d>1</d></b>    <c>2</c></a><a>    <c>2</c>    <b><d>1</d></b></a>XML;$xml = simplexml_load_string($s);$t = $xml->xpath('///a');$t = array_map('objectToarray', $t);//print_r($t);var_dump($t[0] == $t[1]);function objectToArray($d) {   if (is_object($d)) {     $d = get_object_vars($d);   }  if (is_array($d)) {     return array_map(__FUNCTION__, $d);   } else {     return $d;   } }
bool(true)
我还想用phpQuery实现的 看你写出来了我就不贴出来了

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
