Need to Edit 30 XML Files in Bulk

i have 30 xml files and i want to edit them in bulk to replace 4 lines in each of them.

the lines have following format:

<administrator>
<setting> some text </setting>
<action> some text </action>
</administrator>

i want to replace the whole paragraph with following:

<user>
<options> none </options>
<command> some text </command>
</user>

so basically i want to replace existing text with new text but 3rd line requires the text within tags unchanged.

can anyone pls help? any batch script or software?

 

thnx to forum member LostED i was able to accomplish the task.
