Are you sure that LNodeFileAddedElement is not NULL? Are you sure that
LNodeAddedFileList has at least 2 elements (i.e. that "Added" has at
least two "Path" child elements)? Have you tried running your program
inside a debugger to actually see what it's happening?

No, the node will not be in the tree anymore, but the pointer to
it will
still be valid (e.g. you can attach it to a different element of the
same tree).
Also, be careful that the list returned by getElementsByTagName is
"live" and will immediately reflect the removal of the node (i.e.
after
removeChild, item(1) will return what was previously accessed by
item(2))
