Solution 1

Your XPath query isn't correct. Name is not an attribute but an element. It should be something like this:

/AdminTools/App/Name[text()='Test1']

Thank you so much i did make the change it didnt work like i thought it would. Instead of deleting the whole group it deleted just the name from that group. How can i get it to delete the wholegroup for test1?

Try RemoveAll();
