结合两个XML PHP [英] Combine two XML PHP

问题描述

我正在尝试合并两个或更多xml文件以便更好地使用。假设我有两个XML文件，我想在将数据提取到表中之前将它们组合起来。

I'm trying to combine two or more xml files for better use. Let's say I have two XML files and I want to combine their content before extract their data into a table.

<table id="rounded-corner">
    <tr>
            <th>Title</th>
            <th>Download Link</th>
            <th>Language</th>
    </tr>


<?php

        $xml_request_url = 'file.xml';
        $xml = new SimpleXMLElement($xml_request_url, null, true);



        foreach ( $xml->results->content as $item )
        {

        echo "


<tr><td>" . $item->movie . "</td><td><a href=" . $item->download . ">Download Link</a>    </td><td>" . $item->language . "</td></tr>
";

}

        ?> </table>

你能给我一个如何做的例子吗？我不想为我拥有的每个XML文件制作表格。

Can you give me an example of how to do it? I don't want to make tables for each XML file I have.

<find>
<base>
http://www.example.com
</base>
<results items="2" itemsfound="2">
<song>
  <downloadlink>
  http://example.com/dldlink.php?lk=43543
  </downloadlink>
  <format>
  mp3
  </format>
</song>
<song>
  <downloadlink>
  http://example.com/dldlink.php?lk=87798
  </downloadlink>
  <format>
  mp4
  </format>
 </song>
 </results>
 </find>

推荐答案

你的问题其实并不是问如何加入两个XML文件，但更准确地说是如何从两者中创建一个迭代器。这可以通过使用 AppendIterator 来实现：

Your question actually is not asking about how to join two XML files, but more precisely how to create one iterator out of the two. That's possible by using the AppendIterator:

<table id="rounded-corner">
    <tr>
            <th>Title</th>
            <th>Download Link</th>
            <th>Language</th>
    </tr>
<?php

    $content = new AppendIterator();
    $content->append(new IteratorIterator(simplexml_load_file('file1.xml')->results->content));
    $content->append(new IteratorIterator(simplexml_load_file('file2.xml')->results->content));
    foreach($content as $item)
    {
?>
    <tr>
        <td><?= $item->movie ?></td>
        <td><a href="<?= $item->download ?>">Download Link</a></td>
        <td><?= $item->language ?></td>
    </tr>
<?php
    }
?>
</table>
