Transformation of

Hello List,

I have the following XML in form of a variable:

input:
<XML>
	<item>vlue</item>
	<item>%special value%</item>
	<item>vlue</item>
	<item>%special value%</item>
	<unkown_items/>
	<unkown_items/>
</XML>

I want to transform the variable into another variable, having all <item>s
values which contain a '%' changed into other values. (like "super special
value" instead of "%special value%")
My problem is, that there are planty of unknown items in the variable that I
dont know and that might change. But I want the XML structure to stay as it
is, and just replace some items values.

output:
<XML>
	<item>vlue</item>
	<item>super special value</item>
	<item>vlue</item>
	<item>super special value</item>
	<unkown_items/>
	<unkown_items/>
</XML>

How can I do this?

thanks!

Jan
