这是我的xml文件:
<device name=" name ">
<interface>
<ip > someip </ip>
</interface>
<display>
<name> \\.\DISPLAY1 ( 1920 X 1080 )</name>
</display>
<output>
<audio> Speakers (High Definition Audio </audio>
<audio> Digital Audio (S/PDIF) (High De </audio>
<audio> Digital Audio (S/PDIF) (High De </audio>
</output>
这是我的PHP代码:
<body style="font-family: Arial">
<?php
$xml=simplexml_load_file("device.xml");
var_dump($xml);
$attr = $xml->device->attributes()->name;
?>
<div id="leftDiv">
<ul id="menu">
<li><?php echo $attr; ?></li>
</ul>
</div>
<div id="mainDiv">
</div>
<div id="rightDiv">
</div>
我想访问设备的名称属性并获取其值,但我总是收到错误:main():第30行的C:\ xampp \ htdocs \ Project \ index.php中不再存在节点第30行是这一行:$ attr = $ xml-&gt; device-&gt; attributes() - &gt; name;怎么了?
答案 0 :(得分:1)
php文件代码
从device
$xml->device->attributes()->name;
<body style="font-family: Arial">
<?php
$xml=simplexml_load_file("device.xml");
var_dump($xml);
$attr = $xml->attributes()->name;
?>
<div id="leftDiv">
<ul id="menu">
<li><?php echo $attr; ?></li>
</ul>
</div>
<div id="mainDiv">
</div>
<div id="rightDiv">
</div>
xml文件
错过</device>
到文件结尾,所以把它放在
<device name=" name ">
<interface>
<ip > someip </ip>
</interface>
<display>
<name> \\.\DISPLAY1 ( 1920 X 1080 )</name>
</display>
<output>
<audio> Speakers (High Definition Audio </audio>
<audio> Digital Audio (S/PDIF) (High De </audio>
<audio> Digital Audio (S/PDIF) (High De </audio>
</output>
</device>
