解析xml文件并插入mysql数据库 [英] Parse xml-file and insert into mysql database

问题描述

我正在尝试解析xml文件并将其插入mysql数据库. xml文件(syntest.xml)如下所示:

I'm trying parse an xml file and insert it into an mysql database. The xml file (syntest.xml) looks like this:

<synonyms>
<syn level="4.0"><w1>LP</w1><w2>vinylskiva</w2></syn>
<syn level="3.7"><w1>OK</w1><w2>javisst</w2></syn>
<syn level="4.6"><w1>OS</w1><w2>operativsystem</w2></syn>
</synonyms> 

我已经使用simplexml_load_file解析了xml文件，并且当我使用foreach循环在浏览器中打印记录时，该循环遍历了所有记录，并且一切正常.但是，当我尝试将数据插入数据库时​​，循环不会迭代，仅插入一条记录.

I have parsed the xml file using simplexml_load_file, and when I use an foreach loop to print the records in the browser the loop goes through all records and everyting looks fine. But when I try to insert the data into the database, the loop doesnt iterate and only one record is inserted.

代码如下:

<?php

$con = mysql_connect("localhost","user","username");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

mysql_select_db("db_name", $con);


if(!$xml=simplexml_load_file('syntest.xml')){
trigger_error('Error reading XML file',E_USER_ERROR);
}



foreach ($xml as $syn) {
$w1 = $syn->w1;  
$w2 = $syn->w2;     
}

$sql="INSERT INTO db_name (w2, w1)
VALUES
('$w1','$w2')";

if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "Records added";

mysql_close($con)
?>    

非常感谢所有帮助！

推荐答案

mysql_query的位置不正确.您必须在循环中插入记录:

The place of mysql_query isn`t correct. You must insert records in loop:

foreach ($xml as $syn) 
{
    $w1 = $syn->w1;  
    $w2 = $syn->w2;  

    $sql    = "INSERT INTO db_name (w1, w2) VALUES ('$w1','$w2')";
    $query  = mysql_query($sql);

    if (!$query)
    {
        echo ('Error: ' . mysql_error());
    }
    else 
    {
        echo "Record added";
    }
}
mysql_close($con);
