Question

这是我的代码：

<?php
$dom = new DOMDocument();
$dom->load('http://services.gisgraphy.com/geoloc/search?lat=22.298569900000000000&lng=70.794301799999970000&radius=7000', true);
$dom->save('filename.xml');
?>

我得到这种类型的输出：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<results xmlns="http://gisgraphy.com">

        <country_flag_url>/images/flags/IN.png</country_flag_url>
    </result>
</results>

在上面的XML文件中，我想将name节点值中的特殊字符转换为简单字符，例如Rājkot包含我想要转换为简单ā字符的特殊字符a。

下面的代码使用SimpleXML扩展来遍历每个result元素，并通过执行字符集转换为UTF-8来修改其中name元素的文本内容。

<?php
  $results = new SimpleXMLElement('http://services.gisgraphy.com/geoloc/search?lat=22.298569900000000000&lng=70.794301799999970000&radius=7000', NULL, TRUE);
  foreach($results->result as $result) {
    $result->name = iconv('utf-8', 'ascii//TRANSLIT', $result->name);
  }
  $results->asXML('results_simple.xml');
?>

以下是使用DOMDocument而不是SimpleXML的上述代码的替代版本...

<?php
  $doc = new DOMDocument();
  $doc->load('http://services.gisgraphy.com/geoloc/search?lat=22.298569900000000000&lng=70.794301799999970000&radius=7000');
  // retrieve all elements with a tag name of "name"
  $names = $doc->getElementsByTagName('name');
  foreach($names as $name) {
    $name->nodeValue = iconv('utf-8', 'ascii//TRANSLIT', $name->nodeValue);
  }
  $doc->save('results_dom.xml');     
?>

最后，此代码使用DOMDocument以递归方式遍历XML数据中的所有元素/节点，将转换应用于每个文本节点的值...

<?php
  function convertNodeValueChars($node) {
    if ($node->hasChildNodes()) {
      foreach ($node->childNodes as $childNode) {
        if ($childNode->nodeType == XML_TEXT_NODE) {
          $childNode->nodeValue = iconv('utf-8', 'ascii//TRANSLIT', $childNode->nodeValue);
        }
        convertNodeValueChars($childNode);         
      }
    }      
  } 

  $doc = new DOMDocument();
  $doc->load('http://services.gisgraphy.com/geoloc/search?lat=22.298569900000000000&lng=70.794301799999970000&radius=7000');
  convertNodeValueChars($doc->documentElement);
  $doc->save('results_dom.xml');     
?>
