XML - Return Multiple Values And Align Into Column Format

I am new to working with XML and have a question. I can recover any one value from an XML file but how do I recover 2 values from the same file and align them into a column format.

This is what I have been doing so far:
Dim doc As New System.Xml.XmlDocument
doc.Load("C:a_xmltestingDev_Clean.xml")
Dim list = doc.GetElementsByTagName("product") 'this returns the product ok
Dim list2 = doc.GetElementsByTagName("product_code") 'this returns the product code ok

I can pass either list into this and recover the values but not both
For Each item As System.Xml.XmlElement In list2
Debug.WriteLine(item.InnerText)
Next
Can I pass 2 GetElementsByTagName into a list?
