  例子

  XML 檔案:

代碼如下



George
John
Reminder
Don't forget the meeting!

PHP 代碼:

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



天空

Array;Array;

The church tower stood against the sky like a finger pointing towards heaven.
教堂的尖塔在天空的映襯下宛如指向天空的手指。


A balloon floated across the sky.
氣球飄過天空。


A bolt of lightning lit up the sky.
(一道)閃電照亮了天空。


A bright moving object appeared in the sky at sunset.
日落西山時,天空出現了一個移動的發亮物體。


A bright rainbow arched above.
一彎明亮的彩虹懸掛在天空。

在PHP語言中我們可以用以下方法取得我們想要的值:

$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:

  例句:The church tower stood against the sky like a finger pointing towards heaven.

  翻譯:教堂的尖塔在天空的映襯下宛如指向天空的手指。

  例句:A balloon floated across the sky.

  翻譯:氣球飄過天空。

  例句:A bolt of lightning lit up the sky.

  翻譯:(一道)閃電照亮了天空。

  例句:A bright moving object appeared in the sky at sunset.

  翻譯:日落西山時,天空出現了一個移動的發亮物體。

  例句:A bright rainbow arched above.

  翻譯:一彎明亮的彩虹懸掛在天空。

  例子,更深入的一個遍曆輸出產生表格

代碼如下

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."
";
}
