 <?php

          require("db_connection.php");


          function parseToXML($htmlStr) 
          { 
              $xmlStr=str_replace('<','&lt;',$htmlStr); 
              $xmlStr=str_replace('>','&gt;',$xmlStr); 
              $xmlStr=str_replace('"','&quot;',$xmlStr); 
              $xmlStr=str_replace("'",'&#39;',$xmlStr); // line 11  
              $xmlStr=str_replace("&",'&amp;',$xmlStr); 
              return $xmlStr; 
          } 

          // Select all the rows in the markers table
          $query = "SELECT transportType,costPerKm,address,teleNo,webLink,lat,lng FROM transportpublic";

          $result = mysql_query($query);
          if (!$result) 
          {
            die('Invalid query: ' . mysql_error());
          }

          header("Content-type: text/xml");

          // Start XML file, echo parent node
          echo '<transportpublic>';

          // Iterate through the rows, printing XML nodes for each
          while ($row = mysql_fetch_assoc($result)){
            // ADD TO XML DOCUMENT NODE
            echo '<marker ';
            echo 'transportType="' . parseToXML($row['transportType']) . '" ';
            echo 'costPerKm="' . $row['costPerKm'] . '" ';
            echo 'address="' . parseToXML($row['address']) . '" ';
            echo 'teleNo="' . $row['teleNo'] . '" ';
            echo 'webLink="' . parseToXML($row['webLink']) . '" ';
            echo 'lat="' . $row['lat'] . '" ';
            echo 'lng="' . $row['lng'] . '" ';
            echo '/>';
          }

          // End XML file
          echo '</transportpublic>';
    ?>

当我在浏览器上运行 GenerateXml.php 时，我感到很兴奋

When I run GenerateXml.php on browser is gives me fillowing

我只知道在根元素之后我不应该解析任何数据，它将被视为垃圾，但在我的 GenerateXml.php 中，我在此行之后不做任何事情

I only got to know that after the root element I shouldn't be parsing any data it'll be taken as junk but in my GenerateXml.php i don't do anything after this line 

echo '</transportpublic>';

<小时>

请帮帮我.

help me please.

推荐答案

根节点是<transportpublic> 但是错误信息显示一个伪造的</html> 在它之前关闭标签.XML 解析器可能认为 <html> 是根节点，因此 XML 的其余部分是错误提到的 文档元素之后的垃圾.

The root node is <transportpublic> but the error message shows a bogus </html> close tag right before it. The XML parser probably thinks that <html> is the root node, thus the rest of the XML is the junk after document element mentioned by the error.
