Script to Search XML Files for open tags?

Been trying to find a way to write a script which searches a XML file for a open tag. The XML file is a log and when the job is being run the XML file is incomplete. For example there's a <Tag1> but not a </Tag1>. I've tried using XML DOM to search the XML file for open tags have have had no luck.
 
Any ideas would be appreciated.

I'm not sure how the VBS regex engine will handle it, but try this regex:
 
"^((?:<(\w++)[^>]*+(?<!/)>(?1)</\2?|[^<>]++|<\w[^>]*+/>)*+)$"

Trying to load an incomplete XML structure into an XML DOM object should cause a parse error, because the XML is invalid.

Set xml = CreateObject("MSXML.DOMDocument")
xml.Async = False
xml.ValidateOnParse = True
xml.Load "C:\foo.xml"
WScript.Echo xml.ParseError

Oh yeah, if you just want to verify that the xml is valid, go with 59cobalt's suggestion.

Thanks, the parse error solution does what I need.
 
I can use the xml.parseerror.reason and a IF/Instr statement to output what tag's open.
