What if Xml file not found?

Hi, here is my asp code:

set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = false
xml.load(server.MapPath("XML/WES.xml"))

My Question is: how can I stop a error display if the xml file is not found, there might not always be a xml file, and then nothing must happen.

also:

set objNode = xml.SelectSingleNode("employee_details[user_defined_id='0001']")

How do I test to see if the singlenode is found. If it is not found nothing must happen, but at the moment if it is not found I recieve errors.

Please help

VBScript has pretty weak error handling, but that would be how to do it. You could also possibly use the FSO to check for file existance first.

Code:

---

set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = false
On Error Resume Next
xml.load(server.MapPath("XML/WES.xml"))
If Err Then
'handle error
End If
On Error Goto 0 'turn error handling off again, if you wish

---

I'm not sure that this applies to what you are doing but here is how to open an XML file.

VB Code:

XMLdoc.Load strTargetFile
    
    If XMLdoc.parseError.errorCode = 0 Then
        If XMLdoc.readyState = 4 Then
            ' It's OK
        End If
    Else
        Err.Description = XMLdoc.parseError.reason & vbCrLf & _
        "Line: " & XMLdoc.parseError.Line & vbCrLf & _
        "XML: " & XMLdoc.parseError.srcText
        ' Do some sort of error-handeling here using err.description
    End If
