Inserting Nodes between Nodes

Hi,

XML novice here with another question. I need to add a XML node like,

    <child01>
        <child02>
            <text></text>
            <image>image 1</image>
            <image>image 2</image>
        </child02>
    </child01>

Code (markup):

into this node between the ending </child01> and beginning <child01> of the

    <child01>
        <child02>
            <text></text>
            <image>image 1</image>
            <image>image 2</image>
        </child02>
    </child01>    
    <child01>
        <child02>
            <text></text>
            <image>image 1</image>
            <image>image 2</image>
        </child02>
    </child01>

Code (markup):

Does this make sense? I guess im looking for a way to say/do... make a new node with the following values and place it between these other two nodes.

I still am learning XML but i think this can be done. one other thing... i want to do this in PHP if possible, but other languages are ok.

 

woops sorry, my 2nd XML is wrong. here is the correct.

<child01>
	<child02>
		<text></text>
		<image>image 1</image>
		<image>image 2</image>
	</child02>
	<child02>
		<text></text>
		<image>image 1</image>
		<image>image 2</image>
	</child02>
</child01>
<child01>
	<child02>
		<text></text>
		<image>image 1</image>
		<image>image 2</image>
	</child02>
	<child02>
		<text></text>
		<image>image 1</image>
		<image>image 2</image>
	</child02>
</child01>
