xml editing (delete and insert nodes)

<watchFolders>
..........<folder path="C:\test"/>
..........<folder path="C:\New Folder"/>
</watchFolders>

if that is my xml file, is there a way to delete a folder node without using a for loop to cycle through and check each one? if that is the only way, can someone show me the code?
Also, how do I insert a new folder node as the last child of watchFolders node? also some code would be nice.

put it in a dataset object
then play with it as u please.

how do you do that?

dim ds as new Dataset
ds.readXML("C:\myxml.xml")

now you have the dataset to play with
add, delete, modify

for more info on datasets, consult MSDN
