Hi,
I'm deleting nodes in my xml file, and it does seem to work, but then when I
later reload the file and make an xmlNodeList, the nodelist count still
includes the deleted nodes yet the file shows no sign of them. Here is what
I have:

Example of my xml:
<Catalog>
<File ID = "1">
<Customer>Me</Customer>
<Date>Today</Date>

XmlNode.RemoveAll() removes all *child nodes* of the node (including
attributes) but *not* the node itself. Are you sure there is no sign of the
node in the saved XML file? I would expect the file to look like this after
your code runs:

<Catalog>
<File ID = "1">
<Customer>Me</Customer>
<Date>Today</Date>

Thanks. Yes, the <File></File> was in there, I just didn't notice it through
all the data. And I'll definitely give the xpath a shot.
Thanks again,
Mel
