使用PHP SimpleXml解析XML文档疑难解答

我之前使用过xpath来处理XML元素，但是我正努力为这个特定的XML获取正确的语法。使用PHP SimpleXml解析XML文档疑难解答

我试图解析监护人API响应。样本响应：

<response user-tier="approved" current-page="1" start-index="1" page-size="10" pages="1" total="10" status="ok"> 
<results> 
<tag type="series" web-title="Cycling" section-name="Life and style" id="lifeandstyle/series/cycling" api- url="http://content.guardianapis.com/lifeandstyle/series/cycling" section-id="lifeandstyle" web- url="http://www.guardian.co.uk/lifeandstyle/series/cycling"/> 
<tag type="keyword" web-title="Cycling" section-name="Sport" id="sport/cycling" api- url="http://content.guardianapis.com/sport/cycling" section-id="sport" web- url="http://www.guardian.co.uk/sport/cycling"/> 
<tag type="keyword" web-title="Cycling" section-name="Life and style" id="lifeandstyle/cycling" api-url="http://content.guardianapis.com/lifeandstyle/cycling" section-id="lifeandstyle" web-url="http://www.guardian.co.uk/lifeandstyle/cycling"/> 
<results> 
<response>

这是我第一次尝试编码在PHP（我一直在使用卷曲连接）：

$news_items = new SimpleXMLElement($result); //loads the result of the cURL into a simpleXML response 

$news_items = $guardian_response->xpath('results'); 

foreach ($news_items as $item) { //for each statement every entry will load the news_item and the web_url for the document 
    $item_block = "<p class=\"web_title\">"; 
$item_block = "<p class=\"web_url\">"; 
    }

它不获取任何，有没有在我的代码的任何缺陷？

2件东西跳出来。首先在第一行代码中，创建一个XML元素$ news_items，但是您正在对另一个元素运行查询。删除第1行，并将第3行更改为$ news_items = new SimpleXmlElement（$ result） - > xpath（'/ response/results/tag'）。其次，你的xpath不会得到任何标签元素，指定/ response/results/tag来获得它们 – 2011-12-14 15:15:32

<?php 
    function getAttribute($object, $attribute) { 
     foreach($object->attributes() as $a => $b) { 
      if ($a == $attribute) { $return = $b; } 
     } 
     if($return) { return $return; } 
    } 

    try { 
     $xml = simplexml_load_file("parse.xml"); 

     /* Pay attention to the XPath, include all parents */ 
     $result = $xml->xpath('/response/results/tag'); 

     while(list(, $node) = each($result)) { 
      echo getAttribute($node, "type"); 
     } 

    } catch(Exception $e) { 
     echo "Exception on line ".$e->getLine()." of file ".$e->getFile()." : ".$e->getMessage()."<br/>"; 
    } 
?>
