Question

   <Property>
      <Name>TaskId</Name>
      <Value>12345</Value>
   </Property>

   <Property>
      <Name>TaskName</Name>
      <Value>Task1</Value>
   </Property>

   <Property>
      <Name>TaskId</Name>
      <Value>6789</Value>
   </Property>

   <Property>
      <Name>TaskName</Name>
      <Value>Task2</Value>
   </Property>

有谁可以帮助我如何检索所有taskID？

期望的输出： 12345 6789

提前致谢。

Answer 1

这是一个有效的xml吗？我认为不是

但无论如何：

<?php
$test = <<<EOT
    <root>
       <Property>
          <Name>TaskId</Name>
          <Value>12345</Value>
       </Property>

       <Property>
          <Name>TaskName</Name>
          <Value>Task1</Value>
       </Property>

       <Property>
          <Name>TaskId</Name>
          <Value>6789</Value>
       </Property>

       <Property>
          <Name>TaskName</Name>
          <Value>Task2</Value>
       </Property>
    </root>
    EOT;

    $document = @DOMDocument::loadXML($test);

    $xpath = new DOMXpath($document);

    $task_id_elements = $xpath->query('//Property//Name[text()="TaskId"]/following-sibling::*');

    $task_ids = array();
    foreach ($task_id_elements as $task_id_element) {
       $task_ids[] = $task_id_element->nodeValue;
    }

    echo implode(" ",$task_ids);

Answer 2

$objectList = $doc->getElementsByTagName('Object');

for ($o=0;$o<$objectList->length;$o++) 
{
$objectNode = $objectList->item($o);

$properyList = $objectNode->getElementsByTagName('Property');
for ($p=0;$p<$properyList->length;$p++) 
  {
    $propertyNode = $properyList->item($p); 
    $name =  $propertyNode->getElementsByTagName('Name')->item(0)->nodeValue;
    $value = $propertyNode->getElementsByTagName('Value')->item(0)->nodeValue;
    $d[$name] = $value;
  }     
$task_data[] = $d;
unset($d);
}

foreach ($task_data as $td)
{
echo $td["TaskId"].": ".$td["State"]."<br/>"; 
}

另一种方式，这是有效的！ :)
