Checking to see if a tag exists

[rhull]

Is there a way to check to see if a tag exists using getElementsByTagName?

Something like

if objXMLDetails.getElementsByTagName("sentence&quot = FALSE

If I refer to a tag that doesn't exists I get an error,
problem is it may sometimes be used.

And the node order changes so

If objXMLDetails.childNodes(2).childNodes(3).nodeName = "sentence"
works but only if the tag is in that order.

Thanks

simple !
since getElementsByTagName returns a NodeList (i.e., an object) you can always equate it to null to see if the object really exists. Try this:
if(_obj.getElementsByTagName(tagName)==null)
...no such tag exists....
else
...such a tag exists....

okay Im using ASP and when I use

If isNull(objXMLDetails.getElementsByTagName("charges&quot = False Then

else

...
But no matter what it seems to keep returning True,(or at least not null) so I am stumped.

Thanks
