Problem with VBS and XML

Now I need it to rename the XML to the document issuance date (dhEmi), which in this case is a DACTE. I tried to do it here but it does not work ... Could you help me? Here are the codes:

XML snippet:

<?xml version = "1.0" encoding = "ISO-8859-1"?>

VBS file:

DiretorioobjFiles = "C:\DACTE\"
DiretorioDestino = "C:\DACTE\DATA\"

Set FSO = CreateObject("Scripting.FileSystemObject")

Set objFolder = FSO.GetFolder(DiretorioobjFiles)
Wscript.Echo objFolder.Path

Set colFiles = objFolder.Files


For Each objFile in colFiles

On Error Resume Next
If Right(objFile.FileName, 4) = ".xml" Then

    Set objParser = CreateObject("Microsoft.XMLDOM")
    objParser.Load (objFile.path)

    Set ElemList = objParser.getElementsByTagName("chNFe")

Thank you!
