XML到表格式。 我只得到一张桌子。 我需要显示两个表，怎么做？

I get only one table. I need to display two tables, how to do it?

<?xml version="1.0"?>
<books>
  <book> 
    <title>Heart of a Dog</title>
    <author>Mikhail Bulgakov</author>
  </book>
  <book> 
    <title>Postmortem</title>
    <author>Patricia Cornwell</author>
  </book>
</books>

Maybe the wrong foreach loop construct?

 <?php
 $xml = simplexml_load_file('books.xml');
 foreach ($xml as $x) {
    $title = $x->title;
    $author = $x->author;
 }
 ?>

<table width="200" border="1" cellspacing="0" cellpadding="5">
    <tr>
        <td><?php echo "Title: ".$title; ?></td>
    </tr><tr>
        <td><?php echo "Author: ".$author; ?></td>
    </tr>
</table>

According to your output Your code is correct, except just you need to put your Table inside your loop and generate table for each book.

<?php
 $xml = simplexml_load_file('books.xml');
 foreach ($xml as $x) {
    $title = $x->title;
    $author = $x->author;
    ?>
    <table style="margin-top:10px;" width="200" border="1" cellspacing="0" cellpadding="5">
    <tr>
        <td><?php echo "Title: ".$title; ?></td>
    </tr>
    <tr>
        <td><?php echo "Author: ".$author; ?></td>
    </tr>
    </table>
    <?php
 }
 ?>
