Default Need help with documentElement.removeChild

Hi,
I´ve used removechild before when removing a node, like this:

Set objXML = Server.CreateObject("MSXML2.DOMDocument.4.0")
Set oldnode = Server.CreateObject("MSXML2.DOMDocument.4.0")
objXML.async = False
objXML.Load(server.mappath("mylist.xml"))
' Find the node to be deleted
Set oldnode = objXML.documentElement.selectSingleNode("//list/task[name='" & person & "']")
' Remode the node
objXML.documentElement.removeChild(oldnode)
' Save the list
objXML.save server.mappath("mylist.xml")

...which works great when I need to remove the node "task" in this list for example:

<list>
    <task>
        <name>Mike</name>
        <todo>Buy milk</todo>
    </task>
</list>

But when I try to remove a node which is one step deeper in a list I get "msxml4.dll error '80070057' The parameter Node is not a child of this Node." errors.

How do I (in vbscript) remove the first "task" node in the list below? (not based on the list-order, but on the basis of the name (like above))?

<list>
    <mytasks>
        <task>
            <name>Mike</name>
            <todo>Buy milk</todo>
        <task>
        <task>
            <name>Bob</name>
            <todo>Do dishes</todo>
        <task>
</mytasks>
</list>

Any help very appreciated.

/Mike

removeChild needs to be called from the (immediate) parent.
Code:
Set oldnode = objXML.documentElement.selectSingleNode("//list/task[name='" & person & "']")
oldnode.parentNode.removeChild(oldnode)
'save etc.

Ok, this is where I start banging my head on the table...

You might think that removeCHILD would give me a hint, but nooo... :)

Thanks a lot for helping me out. I wont tell you how much time I´ve put in trying different solutions to this earlier today, because... well, it would be embarrasing, hehe.

Thx.
