How to reference duplicate Node Names

[mhnvb]

I have an XML file that literally has hundreds of child nodes that have the same name.
I am need to update a few of them with values.
The child nodes look like this:

<GA>
	<GASM>
		<GASMT>Single Family</GASMT>
		<GSSMEx>0</GSSMEx>
		<GASMf>0</GASMf>
	</GASM>
	<GASM>
		<GASMT>1956</GASMT>
		<GSSMEx>0</GSSMEx>
		<GASMf>0</GASMf>
	</GASM>
	<GASM>
		<GASMT>Standard Home Inspection</GASMT>
		<GSSMEx>0</GSSMEx>
		<GASMf>0</GASMf>
	</GASM>
	<GASM>
		<GASMT>Occupied</GASMT>
		<GSSMEx>0</GSSMEx>
		<GASMf>0</GASMf>
	</GASM>
	<GASM>
		<GASMT>Overcast</GASMT>
		<GSSMEx>0</GSSMEx>
		<GASMf>0</GASMf>
	</GASM>
	<GASM>
		<GASMT>Wood-Destroying Insect</GASMT>
		<GSSMEx>0</GSSMEx>
		<GASMf>0</GASMf>
	</GASM>
</GA>

I figured out that I need to get a node list. There are 8 in the node list. I am using:
Set objNodeList = DOM.documentElement.SelectNodes("//Report/templatehma/genInfo/GA/GASM/GASMT")

This produces the typed value for each node"
MsgBox objNodeList.Item(0 through 7).nodeTypedValue

However, when I try to create a single node to update the nodes, the first node is updated, EG
Set Node = DOM.SelectSingleNode("//" & objNodeList.Item(1 through 7).nodeName) references the first node, which is item(0)

How do I reference each node other than the first node?

Thanks for your help
