How to group elements by containers in xsl?

Question

XSL & XSLT

Hello. Prompt as in xsl it is possible to group elements from the general flow. Those. for example, in the tree there are elements 1,2,3,4 and you need the final html to look like this

<div>
<span>1</span>
<span>2</span>
</div>
<div>
<span>3</span>
<span>4</span>
</div>

The number of elements can be different, the point is that each container has a certain number of elements.
