例子

XML 檔案：

代碼如下

複製代碼

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>George</to>
<from>John</from>
<heading>Reminder</heading>
<body>Don't forget the meeting!</body>
</note>

PHP 代碼：

<?php
if (file_exists('test.xml'))
{
$xml = simplexml_load_file('test.xml');
var_dump($xml);
}

else
{
exit('Error.');
}
?>

輸出：

object(SimpleXMLElement)#1 (4)
{
["to"]=> string(4) "George"
["from"]=> string(4) "John"
["heading"]=> string(8) "Reminder"
["body"]=> string(29) "Don't forget the meeting!"
}

假如有一個“iciba.xml”檔案，其內容如下：

代碼如下

複製代碼

<?xml version="1.0" encoding="UTF-8"?>
<dict num="219" id="219" name="219">
<key>天空</key>
<pos></pos>
<acceptation>Array；Array；</acceptation>
<sent>
 <orig>The church tower stood against the sky like a finger pointing towards heaven.</orig>
 <trans>教堂的尖塔在天空的映襯下宛如指向天空的手指。</trans>
</sent>
<sent>
 <orig>A balloon floated across the sky.</orig>
 <trans>氣球飄過天空。</trans>
</sent>
<sent>
 <orig>A bolt of lightning lit up the sky.</orig>
 <trans>（一道）閃電照亮了天空。</trans>
</sent>
<sent>
 <orig>A bright moving object appeared in the sky at sunset.</orig>
 <trans>日落西山時，天空出現了一個移動的發亮物體。</trans>
</sent>
<sent>
 <orig>A bright rainbow arched above.</orig>
 <trans>一彎明亮的彩虹懸掛在天空。</trans>
</sent>
</dict>在PHP語言中我們可以用以下方法取得我們想要的值：

<?php
$xmldata = simplexml_load_file("iciba.xml");

header("Content-Type: text/html; charset=UTF-8");
print_r($xmldata); //第一部分www.111cn.net

$listcount = count($xmldata->sent);

for($i=0;$i<$listcount;$i++){ //第二部分
$dictlist = $xmldata->sent[$i];
echo " 例句：".$dictlist->orig;
echo " 翻譯：".$dictlist->trans;
}
?>“第一部分”將輸出：

SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [num] => 219
            [id] => 219
            [name] => 219
        )

    [key] => 天空
    [pos] => SimpleXMLElement Object
        (
        )

    [acceptation] => Array；Array；
    [sent] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [orig] => The church tower stood against the sky like a finger pointing towards heaven.
                    [trans] => 教堂的尖塔在天空的映襯下宛如指向天空的手指。
                )

            [1] => SimpleXMLElement Object
                (
                    [orig] => A balloon floated across the sky.
                    [trans] => 氣球飄過天空。
                )

            [2] => SimpleXMLElement Object
                (
                    [orig] => A bolt of lightning lit up the sky.
                    [trans] => （一道）閃電照亮了天空。
                )

            [3] => SimpleXMLElement Object
                (
                    [orig] => A bright moving object appeared in the sky at sunset.
                    [trans] => 日落西山時，天空出現了一個移動的發亮物體。
                )

            [4] => SimpleXMLElement Object
                (
                    [orig] => A bright rainbow arched above.
                    [trans] => 一彎明亮的彩虹懸掛在天空。
                )

)

)“第二部分”將輸出：

例子，更深入的一個遍曆輸出產生表格

代碼如下

複製代碼

eader("content-type:text/html; charset=utf-8"); //設定編碼
$xml = simplexml_load_file('a.xml'); //載入xml檔案 $lists和xml檔案的根節點是一樣的
echo $xml->company." ";
echo $xml->town." id:";
echo $xml->town['id']." parent:";
echo $xml->town['parent']." ";

echo " 迴圈讀取: ";
foreach($xml->user as $users){ //有多個user，取得的是數組，迴圈輸出
 echo "------------------- ";
 echo "姓名:".$users->name." ";
 echo "編號:".$users->age." ";
 echo "性別:".$users->age['sex']." ";
 echo "序號:".$users->height." ";
}

echo " 迴圈讀取: ";
foreach($xml->town as $towns){ //有多個user，取得的是數組，迴圈輸出
 echo "------------------- ";
 echo "id:".$towns['id']." ";
 echo "歸屬:".$towns['parent']." ";
 echo "地區:".$towns." ";
}
