我有以下代码。

 <entry>
  <job:location>
   <job:id>24</job:id>
   <job:region>6</job:region>
  </job:location>
 </entry>

我的命名空间有问题。如何读取 SimpleXML 中 job:region 标签的内容。

试试这个：

 <?php 
    $entry = simplexml_load_file('entry.xml');        
    printf("%s\n", $entry->children('job', true)->location->region);  
 ?>

您应该注册作业命名空间，然后您可以使用注册的命名空间- XPath 中的前缀来选择您想要的内容：

$sxe = new SimpleXMLElement($xml);

$sxe->registerXPathNamespace('job', 'http://example.org/you-did-not-provide-the-job-namespaceURI-in-your-example');
$result = $sxe->xpath('//entry/job:location/job:region');

foreach ($result as $location) {
  echo $location . "\n";
}

You should register the job namespace, then you can use the registered namespace-prefix in an XPath to select what you want:

$sxe = new SimpleXMLElement($xml);

$sxe->registerXPathNamespace('job', 'http://example.org/you-did-not-provide-the-job-namespaceURI-in-your-example');
$result = $sxe->xpath('//entry/job:location/job:region');

foreach ($result as $location) {
  echo $location . "\n";
}

我会动态地做。

$xml = @simplexml_load_string($path) // loads your valid xml data
foreach($xml->channel->item as $entry) {

  $namespaces = $entry->getNameSpaces(true);
  foreach($namespaces as $ns=>$value)
  {
    $job = $entry->children($namespaces[$ns]);
    $author = (string)$job->creator;

    if ($author != "")
    {
      $someVariable = (string) $dc->creator;
    }
}

I would do it dynamically.

$xml = @simplexml_load_string($path) // loads your valid xml data
foreach($xml->channel->item as $entry) {

  $namespaces = $entry->getNameSpaces(true);
  foreach($namespaces as $ns=>$value)
  {
    $job = $entry->children($namespaces[$ns]);
    $author = (string)$job->creator;

    if ($author != "")
    {
      $someVariable = (string) $dc->creator;
    }
}
