I have an existing XML document with more number of nodes and I want to insert a new node, but at a certain position.
The document looks something like:
<a>...</a>
<c>...</c>
<e>...</e>
</root>
... can be considered as xml tags a.../a, c.../c, e.../e. (formatting issue)
The new nodes should be inserted in alphabetical order in between the nodes, resulting in:
new node
new node
new node
How can I use XPath in TCL to find the existing node and insert new node before or after it.
I also want to preserve the order, since the existing tags in XML document are in alphabetical order.
At present I am using tdom package.
Does anyone have an idea on how to insert such a node?

set insertPoint [$container selectNodes a]
set toAdd [$doc createElement b]
$toAdd appendChild [$doc createTextNode "234"]
$container insertAfter $insertPoint $toAdd
set insertPoint [$container selectNodes c]
set toAdd [$doc createElement d]
$toAdd appendChild [$doc createTextNode "456"]
$container insertAfter $insertPoint $toAdd
# Write back out
set f [open $filename w]
puts $f [$doc asXML -indent 4]
close $f
