我有一个看起来像这样的XML文件:
<?xml version="1.0" encoding="UTF-8"?>
<facilities>
<areas>
<area name="Rocket">
<trails>
<trail name="This Skiway" status="CLOSED" difficulty="novice"/>
</trails>
</area>
</areas>
</facilities>
我正在尝试使属性以一种形式显示,以便我可以替换它们。我已经成功使用了getElementsbyTagName并替换了标签中的内容,但是当我引入XPath并尝试替换属性时,它只是行不通。
我正在使用的代码是这样:
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<?php
$xml = new DOMDocument('1.0', 'utf-8');
$xml->formatOutput = true;
$xml->preserveWhiteSpace = false;
$xml->load('examples.xml');
$xpath = new DOMXpath($xml);
$name = $xpath->query("/facilities/areas/area[@name='Rocket']/trails/trail[@name='This Skiway']/@name")->item(0);
$status = $xpath->query("/facilities/areas/area[@name='Rocket']/trails/trail[@name='This Skiway']/@status")->item(0);
$xpath->replaceChild($name, $name);
$xpath->replaceChild($status, $status);
?>
<?php
if (isset($_POST['submit']))
{
$name->nodeValue = $_POST['namanya'];
$status->nodeValue = $_POST['statusnya'];
htmlentities($xml->save('examples.xml'));
}
?>
<form method="POST" action=''>
name <input type="text-name" value="<?php echo $name->nodeValue ?>" name="namanya" />
<span><label for='statusnya'>status </label>
<select name="statusnya" id="statusnya">
<option selected value="<?php echo $status->nodeValue ?>"><?php echo $status->nodeValue ?></option>
<option value="OPEN">OPEN</option>
<option value="CLOSED">CLOSED</option>
<option value="RACING CLOSURE">RACING CLOSURE</option>
</select></span>
<input name="submit" type="submit" />
</form>
不知道我在做什么错,但我认为我的xpath查询不好。非常感谢!

Nigel Ren建议的答案只是删除这两行,因为它们不再适用:
