The nextSibling property returns the next node in the parent's child list, or null if there is none or the node is of a type that cannot be a child node (Attr, Document, DocumentFragment).

The example that follows uses the 'passeriformes.xml' file which details the bird families belonging to that order. It first gets the firstChild node of the root, and then uses the nextSibling property to print the text of the node that follows it.

XML:
<passeriformes>
   <family>
      <f_name>Alaudidae</f_name>
      <species>Woodlark</species>
      <species>Skylark</species>
      <species>Shore Lark</species>
   </family>
   <family>
      <f_name>Motacillidae</f_name>
      <species>Rock Pipit</species>
      <species>Water Pipit</species>
      <species>Yellow Wagtail</species>
   </family>
   <family>
      <f_name>Turdidae</f_name>
      <species>Robin</species>
      <species>Nightingale</species>
      <species>Blackbird</species>
   </family>
</passeriformes>

Code (VBScript):
Set objXMLDoc = CreateObject("Microsoft.XMLDOM")
objXMLDoc.async = False
objXMLDoc.load("passeriformes.xml")

Dim child1, child2
Set child1 = objXMLDoc.documentElement.firstChild
Set child2 = child1.nextSibling
document.write(child2.text)

Output:
Motacillidae Rock Pipit Water Pipit Yellow Wagtail
