XML parser in vb.net

I hope I'm asking the right question, in the right place.

I have some an xml file generated that will eventually be passed in a word document, but till it gets there I have some values I need to pass into the xml file.

For instance, everytime the word %@ProspectName% is seen in xml I Need it to go into a sql database and find the value for that and replace it in the xml document. I hope this makes sense, and I hope I'm not shooting in the dark here.

Thanks!!

Great! I figured out though...

how to load the xml document, and I can change Items in the xml as long as i know the index of the item. Using this...

Code:

---

Private Sub xmlChange()

        Dim DS As New DataSet()

        DS.ReadXml("c:\inetpub\wwwroot\xmlTest\xmlemp.xml")

        DS.Tables(0).Rows(1).Item("Name") = "VALUE TO REPLACE WITH"

      DS.WriteXml("c:\inetpub\wwwroot\xmlTest\xmlemp.xml")

End Sub

---

Now how can I have it search that Dataset for a particular string, and then change the value of that string? For example:

In my xml, i will have keywords such as %@Prospects% and %@Name% that I want to replace with values, but now can I tell the vb to search for those values instead of me having to know where they are beforehand?

Thanks!
