将数据附加到XML文件

Question

使用CubeGallery3D的Im使用XML文件存储。

的XML结构如下： http://pastebin.com/peMxcmYb

我想追加：

<thumbnail preview="This is Preview" previewURL="This is URL" thumb="This is Thumb"> 
     <title><![CDATA[This is Title]]></title> 
     <discription><![CDATA[This is Description]]></discription> 
    </thumbnail> 

到XML文件，用PHP。

我已经开始了这一点：

$xmldoc = new DOMDocument(); 
$xmldoc->load('/theme1157/sample.xml'); 

加载sample.xml中。

有人能告诉我如何在文件中创建一个<thumbnail>元素，并像上面的例子那样向它添加参数+值吗？

Answer 1

试试这个：

<?php 
$xmldoc = new DOMDocument(); 
$xmldoc->load('sample.xml'); 



$thumbnail = $xmldoc->createElement('thumbnail'); 
$thumbnail->setAttribute('preview', 'This is a preview'); 
$thumbnail->setAttribute('previewURL', 'This is a URL'); 
$thumbnail->setAttribute('thumb', 'This is a Thumb'); 

$title = $xmldoc->createElement('title'); 
$title->appendChild($xmldoc->createCDATASection('This is Title')); 
$thumbnail->appendChild($title); 


$description = $xmldoc->createElement('description'); 
$description->appendChild($xmldoc->createCDATASection('This is Description')); 
$thumbnail->appendChild($description); 


$xmldoc->getElementsByTagName('thumbnails')->item(0)->appendChild($thumbnail); 
$xmldoc->save('sample.xml'); 

Answer 2

几乎是相同的JavaScript DOM操作 - 它应该是这样的......

$xmlThumbnail = $xmlDoc->createElement('thumbnail'); 
$xmlTitle = $xmlDoc->createElement('title'); 
$xmlDescription = $xmlDoc->createElement('discription'); 

$xmlThumbnail->setAttribute('preview', $sPreview); 
$xmlThumbnail->setAttribute('previewurl', $sPreviewURL); //technically in XML attributes must be in lowercase 
$xmlThumbnail->setAttribute('thumb', $sThumbnail); //presumably a path? 

$xmlThumbnail->appendChild($xmlTitle); 
$xmlThumbnail->appendChild($xmlDescription); 

$xmlDoc->appendChild($xmlThumbnail); 
$xmlDoc->save('/theme1157/sample.xml'); 

虽然$xmlDoc->appendChild()可能需要改变，如果这是一个“真正的” XML文档应该有一个容器元素，所以它可能是更多的东西一样$xmlDoc->firstChild->appendChild($xmlThumbnail);
