例子
XML 文件:
代码如下
<?xmlversion="1.0"encoding="ISO-8859-1"?>
<note>
<to>George</to>
<from>John</from>
<heading>Reminder</heading>
<body>Don'tforget the meeting!</body>
</note>
PHP代码:
<?php
if(file_exists('test.xml'))
{
$xml =simplexml_load_file('test.xml');
var_dump($xml);
}
else
{
exit('Error.');
}
?>
输出:
object(SimpleXMLElement)#1(4)
{
["to"]=> string(4) "George"
["from"]=> string(4)"John"
["heading"]=> string(8) "Reminder"
["body"]=> string(29)"Don't forget the meeting!"
}
假如有一个“iciba.xml”文件,其内容如下:
代码如下
<?xmlversion="1.0" encoding="UTF-8"?>
<dict num="219" id="219"name="219">
<key>天空</key>
<pos></pos>
<acceptation>Array;Array;</acceptation>
<sent>
<orig>Thechurch tower stood against the sky like a finger pointing towardsheaven.</orig>
<trans>教堂的尖塔在天空的映衬下宛如指向天空的手指。</trans>
</sent>
<sent>
<orig>Aballoon floated across thesky.</orig>
<trans>气球飘过天空。</trans>
</sent>
<sent>
<orig>Abolt of lightning lit up thesky.</orig>
<trans>(一道)闪电照亮了天空。</trans>
</sent>
<sent>
<orig>Abright moving object appeared in the sky atsunset.</orig>
<trans>日落西山时,天空出现了一个移动的发亮物体。</trans>
</sent>
<sent>
<orig>Abright rainbow archedabove.</orig>
<trans>一弯明亮的彩虹悬挂在天空。</trans>
</sent>
</dict>在PHP语言中我们可以用以下方法取得我们想要的值:
<?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 "<br/>例句:".$dictlist->orig;
echo "<br/>翻译:".$dictlist->trans;
}
?>“第一部分”将输出:
SimpleXMLElementObject
(
[@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 skylike a finger pointing towards heaven.
[trans] =>教堂的尖塔在天空的映衬下宛如指向天空的手指。
)
[1] => SimpleXMLElement Object
(
[orig] => A balloon floated across the sky.

)
[4] => SimpleXMLElement Object
(
[orig] => A bright rainbow arched above.
[trans] =>一弯明亮的彩虹悬挂在天空。

)
)“第二部分”将输出:
例句:The church tower stood against the sky like a finger pointing towardsheaven.
翻译:教堂的尖塔在天空的映衬下宛如指向天空的手指。
例句:A balloon floated across the sky.
翻译:气球飘过天空。
例句:A bolt of lightning lit up the sky.
翻译:(一道)闪电照亮了天空。
例句:A bright moving object appeared in the sky at sunset.
翻译:日落西山时,天空出现了一个移动的发亮物体。
例句:A bright rainbow arched above.
翻译:一弯明亮的彩虹悬挂在天空。
例子,更深入的一个遍历输出生成表格
代码如下
eader("content-type:text/html;charset=utf-8"); //设置编码
$xml = simplexml_load_file('a.xml'); //载入xml文件$lists和xml文件的根节点是一样的
echo $xml->company."<br>";
echo$xml->town."<br>id:";
echo$xml->town['id']."<br>parent:";
echo$xml->town['parent']."<br>";
echo"<br>循环读取:<br>";foreach($xml->user as $users){ //有多个user,取得的是数组,循环输出
echo "-------------------<br>";
echo"姓名:".$users->name."<br>";
echo"编号:".$users->age."<br>";
echo"性别:".$users->age['sex']."<br>";
echo"序号:".$users->height."<br>";
}
echo"<br>循环读取:<br>";
foreach($xml->town as $towns){//有多个user,取得的是数组,循环输出
echo "-------------------<br>";
echo"id:".$towns['id']."<br>";
echo"归属:".$towns['parent']."<br>";
echo"地区:".$towns."<br>";
}
