在下面的 xml 响应中

<response>
  <lst name="responseHeader">
    <int name="status">0</int>
    <int name="QTime">1</int>
  </lst>
  <lst name="initArgs">
    <lst name="defaults">
      <str name="config">../conf/dataconfig.xml</str>
    </lst>
  </lst>
  <str name="status">busy</str>
  <str name="importResponse">A command is still running...</str>
  <lst name="statusMessages">
    <str name="Time Elapsed">0:0:7.942</str>
    <str name="Total Requests made to DataSource">1</str>
    <str name="Total Rows Fetched">8831</str>
    <str name="Total Documents Processed">8830</str>
    <str name="Total Documents Skipped">0</str>
    <str name="Full Dump Started">2013-06-03 22:15:11</str>
  </lst>
  <str name="WARNING">
    This response format is experimental. It is likely to change in the future.
  </str>
</response>

我需要访问两个值:

<str name="status">busy</str>  --  busy
<str name="Total Rows Fetched">8831</str>  --  8831

使用下面的代码:

$xml = simplexml_load_string($string); 
echo $xml->str[0];

我可以访问值"busy"但我不知道如何访问"8831"

使用 Xpath:

$xml = simplexml_load_string($x); // assuming XML in $x
echo $xml->xpath("//str[@name='status']")[0];

并对其他值做同样的事情。

使用var_dump($xml); 理解 xml 对象。阅读示例 #1 解释一个 XML 字符串示例http://php.net/manual/en/simplexmlelement.attributes.php 这将类似于,

foreach($xml->foo[0]->attributes() as $a => $b) { 
      if($a=="Total Rows Fetched"){
         echo $b;    
      }    
  }
