Help with checking for existing data element
Hi,
How do you check if data element exist before including in xml file to avoid duplicate data elements?
Dim xdoc As XDocument = XDocument.Load(Application
Dim results = (From n In xdoc.Root.Descendants("AOP
Select n).ToList()
results.ForEach(Sub(n) n.Add(<CA></CA>))
xdoc.Save(Application.Star

Hi Fernando,
Below is an example of the xml file. I would like to add <CA></CA> at the end of the table if it does not already exist.
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root>
<Table1>
<SN>9089</SN>
<AGD>BHJK</AGD>
<CHPT>104</CHPT>
<RIC>YUXRT</RIC>
</Table1>
</Root>
Thanks,
victor

Thank You.
Not a problem Victor, glad to help.
Please supply a true representation of the XML file.
When you say,, "checking for existing data element", is this within one parent node or in all nodes?
Does this mean that you want to insert the an empty <CA></CA> node in the document?
Where in the document do you want to insert the node?
