"node.InsertAfter" method only inserts node on final call

[chris yoker]

hiya,

I succesfully return a "nodeList" thru the "xmlDoc.SelectNodes" method.
This nodeList is taken from a repetitive, uniform xml doc.

I can successfully append a child node at the correct position using the
following code:

<code>
<!--Node inserted into corrrect position in nodeList(0)-->
nodeList(0).InsertAfter(additionalNode, nodeList(0).ChildNodes(5))
</code>

however, as soon as I try to do the same with nodeList(1), then
apparently the SAME code that previously inserted the node into
nodeList(0) doesn't do its job.

<code>
<!--Node NOT inserted into nodeList(0)-->
nodeList(0).InsertAfter(additionalNode, nodeList(0).ChildNodes(5))

<!--Node inserted into corrrect position in nodeList(1)-->
nodeList(1).InsertAfter(additionalNode, nodeList(1).ChildNodes(5))
</code>


Surely, If i am using the "InsertAfter" method, then the node should
have been inserted BOTH times?

As a test, I swapped my code round, and I can confirm that the node is
ONLY inserted on the 2nd call.

<code>
<!--Node NOT inserted into nodeList(1)-->
nodeList(1).InsertAfter(additionalNode, nodeList(1).ChildNodes(5))

<!--Node inserted into corrrect position in nodeList(0)-->
nodeList(0).InsertAfter(additionalNode, nodeList(0).ChildNodes(5))
</code>

Can someone comment?I have been spent a bit of time on this, and am no
further forward.
Even if i could get hold of some sample code in vb / c# that did this,
then I'm sure I could take it from there ;-)

ta,

Surely it is inserted both times but it is getting removed prior
inserting it the second time. There's no 'InsertArfter' method in
the standard DOM interfaces but if you look at the
'Node.appendChild' [1], 'Node.insertBefore' [2] and
'Node.replaceChild' [3] documentation you would find:

If the 'newChild' is already in the tree, it is first removed.
