在PHP DOM中合并xml [英] Merge xml in PHP DOM

问题描述

我想将一个PHP DOMDocument合并到另一个文件中.

i want to merge a PHP DOMDocument in another..

//this creates the DOM which will be imported
function element_index(..)
{
$skrit=new DOMDocument();
$skrit->loadXML('<krits:kriti xmlns:krits="http://test.de/krits">..</krits:kriti>');
return $skrit;
}

function crawl_xml($element)
{
//thats the line where to get the result and merge      
$skrit=element_index(..);
$temp3=$skrit->documentElement->cloneNode(true);
$element->appendChild($xpIn->importNode($temp3));
}

//thats how i start the recurisve walking through Nodes
$xpIn = new DOMDocument();
crawl_xml($xpIn->firstChild);

输入/输出应如下所示:

The input/output should like this:

<!--input-->
<all><one/></all>

<!--input new to add-->
<krits:kriti xmlns:krits="http://test.de/krits">..</krits:kriti>

<!--ouput-->
<all><krits:kriti xmlns:krits="http://test.de/krits">..</krits:kriti><one><krits:kriti xmlns:krits="http://test.de/krits">..</krits:kriti></one></all>

也许importNode可能不是一个好选择?我使用cloneNode的原因是希望避免递归调用的问题.所以我在做什么错呢?感谢您的帮助！

maybe importNode might be not a good choice? The cloneNode I used because I hoped to avoid problems with recursive call.. So what i am doing wrong? Thanks for your help!

推荐答案

如果要导入整个节点子树(而不仅仅是节点本身)，则需要设置 $ deep 到importNode中的 true :

If you want to import the whole node sub-tree (and not just the node itself), you need to set $deep to true in importNode:

$domDocument->importNode($node, true);
