Question

Is there any way to copy (deep) element from one DOMDocument instance to another?

<Document1>
  <items>
    <item>1</item>
    <item>2</item>
    ...
  </items>
</Document1>

<Document2>
  <items>
  </items>
</Document>

I need to copy /Document1/items/* to /Document2/items/.

It seems that DOMDocument doesn’t have methods to import nodes from another DOMDocument. It even can’t create nodes from xml text.

Of course I can achieve this using string operations, but maybe there is simpler solution?

You can use the cloneNode method and pass a true parameter. The parameter indicates whether to recursively clone all child nodes of the referenced node.
