我试图找到一种简单的方法来使用 php 解析eXist 响应，而无需安装第三方类。

这是我想解析的响应类型：

<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_load_string php 函数，但我得到了一个没有错误的空 SimpleXMLElement 对象。

我想摆脱这个响应的 XML 文件列表。

谢谢

设置命名空间，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'));

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

$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);

产生这个：

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