Im new with xml and vbscript , I need some help to extract the value of "entrada-fecha-y-hora" of the first line <ev:evento> and "salida-fecha-y-hora" of the second line <ev:evento> to export to an excel file, my vbscript is the following:

Dim s
Dim t
Set oDOM = CreateObject("Msxml2.DOMDocument.3.0")
oDOM.preserveWhiteSpace = False
oDOM.Load strXMLFileToProcess ' I use this to pass the file name
Set Root = oDOM.selectNodes("//dia:detalle-de-eventos/ev:evento")
For x = 0 to Root.lenght - 1
      s = s & Root(x).selectSingleNode("@entrada-fecha-y-hora").text
       t = t & Root(x).selectSingleNode("@salida-fecha-y-hora").text
Next
MsgBox s 'For test only
MsgBox t 'For test only

and the xml file is

<?xml version="1.0" encoding="UTF-16"?>

Assuming both attributes are present in all evento nodes you could use the following code instead of the for-next loop to fetch the start from the first evento and the end from the last evento:
Set Root = oDOM.selectNodes("//dia:detalle-de-eventos/ev:evento")
s = Root(0).selectSingleNode("@entrada-fecha-y-hora").text
t = Root(Root.length - 1).selectSingleNode("@salida-fecha-y-hora").text
MsgBox "Start: " & s & vbCrLf & "End: " & t
