MSXML2.DOMDocument30 and xml

[pelegk2]

i am parsing an XML using MSXML2.DOMDocument40
(almost everything is written)
but i look for a way how can i check if a certain node dosent exist
when i try to access by "getElementsByTagName" like this :

objXMLDOM.getElementsByTagName("xxx") 

how can i check if a node exist or not so i wont get an error ?
thnaks in advance

Since getElementsByTagName returns a list of nodes, simply check for the length property this way:

Dim xNodeList   As IXMLDOMNodeList

Set xNodeList = xDoc.getElementsByTagName("MyNode")  'returns list of nodes with this name

MsgBox xNodeList.length '0 if no matches

where xDoc is your MSXML.DOMDocument variable.

Actually that's for HTML only... the XML section at MSDN can be found here:
