如何用PHP解析eXist XQuery响应？

我试图找到一种简单的方法，在不安装第三方类的情况下，用php解析存在响应

这是我要分析的响应类型：

<exist:result xmlns:exist="http://exist.sourceforge.net/NS/exist">
  <exist:collection name="xData" path="/db/SBXXX/00000000-00000000/sapData" created="2010-07-15T16:12:09.135-05:00">
    <exist:resource name="xDataData1.xml" size="1565" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-20T23:42:09.584-05:00"/>
    <exist:resource name="xDataData10.xml" size="805" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-21T01:27:09.614-05:00"/>
    <exist:resource name="xDataData11.xml" size="806" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-21T01:27:22.005-05:00"/>
    <exist:resource name="xDataData12.xml" size="1565" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-21T01:42:15.768-05:00"/>
    <exist:resource name="xDataData13.xml" size="805" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-21T01:57:09.749-05:00"/>
  </exist:collection>
</exist:result>

我正在尝试使用simplexml\u load\u stringphp函数，但是我得到了一个空的simplexmlement对象，没有任何错误

我想从这个响应中得到XML文件列表

谢谢

设置名称空间，并使用xpath：

    $xml = '<exist:result xmlns:exist="http://exist.sourceforge.net/NS/exist">
  <exist:collection name="xData" path="/db/SBXXX/00000000-00000000/sapData" created="2010-07-15T16:12:09.135-05:00">
    <exist:xmlObject name="xDataData1.xml" size="1565" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-20T23:42:09.584-05:00"/>
    <exist:resource name="xDataData10.xml" size="805" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-21T01:27:09.614-05:00"/>
    <exist:resource name="xDataData11.xml" size="806" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-21T01:27:22.005-05:00"/>
    <exist:resource name="xDataData12.xml" size="1565" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-21T01:42:15.768-05:00"/>
    <exist:resource name="xDataData13.xml" size="805" created="1969-12-31T18:00:00.000-06:00" last-modified="2010-09-21T01:57:09.749-05:00"/>
  </exist:collection>
</exist:result>';
$xmlObject = simplexml_load_string($xml);
$xmlObject->registerXPathNamespace('e','http://exist.sourceforge.net/NS/exist');
var_dump($xmlObject->xpath('//e:resource'));

$xml='1！'
';
$xmlObject=simplexml\u load\u字符串（$xml）；
$xmlObject->registerXPathNamespace（'e'，'http://exist.sourceforge.net/NS/exist');
var_dump（$xmlObject->xpath（'//e:resource'））；

使用DOMDocument和DOMXPath是访问这些属性的最“正确”的方法：

$xml = '<exist:result xmlns:exist="http://exist.sourceforge.net/NS/exist">
  <exist:collection name="xData">
    <exist:resource name="xDataData1.xml"/>
    <exist:resource name="xDataData10.xml"/>
  </exist:collection>
</exist:result>
';

$dom = DOMDocument::loadXML($xml);
$xpath = new DOMXPath($dom);
$xpath->registerNamespace('exist', 'http://exist.sourceforge.net/NS/exist');

$nodes = $xpath->query('exist:collection/exist:resource');
if (!$nodes->length)
  exit('No nodes found');

$items = array();
foreach ($nodes as $node)
  $items[] = $node->getAttribute('name');

print_r($items);

Array
(
    [0] => xDataData1.xml
    [1] => xDataData10.xml
)
