I want to check in above XML file in tag nodeName is exist or NOT..? For example In <PARAMETER> tag for <PNAME>I_LANG</PNAME> item does not have tag or nodeName like <PGROUP> so in this situation VB script should display error.

For <PNAME>WE20_100_STEP_1</PNAME> the nodeName <PGROUP> tag is exist so this is correct In this way I want to check for which <PNAME> the <PGROUP> tag is not exist.

The following XML <PNAME> node doesn't have corresponding <PGROUP> 1)<PNAME>I_LANG</PNAME> 2)<PNAME>V_LANG</PNAME> 3)<PNAME>I_AGENT</PNAME> 4)<PNAME>I_TYPE</PNAME> for these VB script should display error but I tried with following vb script it only displaying error for <PNAME>I_LANG</PNAME> not for others. Please help

I have tried following vbscript :

   Dim oFS      : Set oFS      = CreateObject("Scripting.FileSystemObject")
   Dim sFSpec   : sFSpec       =        oFS.GetAbsolutePathName("C:\sample.xml")
   Dim objMSXML : Set objMSXML = CreateObject("Msxml2.DOMDocument")
   objMSXML.setProperty "SelectionLanguage", "XPath"
   objMSXML.async = False
   objMSXML.load sFSpec
   objMSXML.validateOnParse = True  
   counter=0
   Set NodeList = objMSXML.documentElement.selectNodes("/ECSC/PARAMETERS/ETPAR_GUIX/item[not(PGROUP)]/PNAME")
  for each item in NodeList
      myPNAME = objMSXML.getElementsByTagName("PNAME").item(counter).text
      If (Left(myPNAME,1)="I") Then
         If objMSXML.getElementsByTagName("PNAME").item(counter).nodeName = "PGROUP"  Then
             msgbox("PGROUP is exist for" &myPNAME)
          Else
              msgbox("PGROUP is NOT exist for" &myPNAME)
         End If
      End If
    counter=counter+1
  Next

回答1:

Since NodeList already contain nodes without corresponding <PGROUP>, you don't need to do If checking anymore inside For Each loop :

Set NodeList = objMSXML.documentElement.selectNodes("/ECSC/PARAMETERS/ETPAR_GUIX/item[not(PGROUP)]/PNAME")
For Each item in NodeList
  myPNAME = item.text
  msgbox("PGROUP is NOT exist for" &myPNAME)
Next
