Remove a parent node and all children based on text value in child

问题

I am trying to read an xml file with vbscript and if the ATTRIBUTE_DATA contains V-3008, I want to delete/remove the whole vuln .... vuln that contains it. - I have tried all different XPath variations and can't come up with the one that will do that. I have had it deleting the entire row that contains it but that is no good. I did search this site first and there isn't a whole lot on this topic: https://stackoverflow.com/search?q=xpath+vbscript+remove+node

Here is some basic code I have started. Thank you.

Set xmlDoc = _
CreateObject("Microsoft.XMLDOM")
xmlDoc.Async = "False"
xmlDoc.Load("C:\Users\somedude\Desktop\xml-development\myfile.xml")

strVulid = "V-3008"
xpath  = "//CHECKLIST/VULN/STIG_DATA/ ATTRIBUTE_DATA[text() = '" & strVulid & "']/ATTRIBUTE_DATA "

For Each n In XMLDoc.SelectNodes(xpath)
    n.parentNode.removeChild(n)
Next

xmlDoc.Save "C:\Users\somedude\Desktop\xml-development\myfile.xml" 
msgbox "done"

Here Is the example XML:

You want the xpath to return <VULN> elements that satisfy the criteria :

......

strVulid = "V-3008"
xpath  = "//CHECKLIST/VULN[STIG_DATA/ATTRIBUTE_DATA = '" & strVulid & "']"

For Each n In XMLDoc.SelectNodes(xpath)
    n.parentNode.removeChild(n)
Next

......

Above xpath return <VULN> having descendant element <ATTRIBUTE_DATA> exactly equals "V-3008".

Use contains() if you meant to match <ATTRIBUTE_DATA> value partially :

xpath  = "//CHECKLIST/VULN[STIG_DATA/ATTRIBUTE_DATA[contains(.,'" & strVulid & "')]]"
