Test if returned object is null - how?

[MrPeds]

Hi,

I am using VBScript to perform some simple XML DOM programming.

I'd basically like to know if there is any way of testing if an object returned from a function call is null?

For example, if I have the following pseudo code:
Dim theObject
Set theObject = xmldoc.selectSingleNode(XPath_string)
if theObject is null then
'do some code if the returned object is null
else
'continue as normal
end if

Are there any functions that test if the 'theObject' is null? I've tried isNull but it doesnt appear to work for objects.

Any help is appreciated, thankyou.

Try:

if theObject is nothing then

Try one of these:
If IsNull(expression) Then

If expression = "" Then

if len(expression) = 0 Then

if expression = nothing Then

if expression = Null Then

One of them should work for you
