How to loop loop through a dataset to update xml file based on rows selected from a grid?

Hello,

I'm trying to update a Link.xml file based on the value of an Fuze.xml file.  How do you loop through the Fuze.xml file and set the Link Files' Fuze_ID = PFuze_ID of the Fuze file where Fuze_ID of the Link File = Fuze_ID of the Fuze file? I started writing the code, but would very much appreciate your help with the proper syntax.

                Dim ds As New DataSet
                ds.ReadXml(Application.StartupPath + "\Link.xml")
                Dim dsFuze As New DataSet
                dsFuzeA.ReadXml(Application.StartupPath + "\Fuze.xml")
             
                Dim dt As DataTable = ds.Tables(0)
                Dim r As DataRow = dt.NewRow
                r!Link_ID = dt.Rows(dt.Rows.Count - 1)("Link_ID") + 1
                r!Fuze_ID = C1FuzeGrid.Columns(0).Value
              '*****************
               For ???????
                If dsFuzeA.Fuze_ID = C1FuzeGrid.Columns(0).Value then
                r!PFuze_ID = dsFuzeA.PFuzeID
                Endif
                Next
              '***************
                dt.Rows.Add(r)
                ds.WriteXml(Application.StartupPath + "\Link.xml")

Thanks,

Victor

Here is the procedure:

1. Loop through rows in link dataset
2. Loop through rows in fuze dataset
3. Check condition for the values in link and fuze ds
4.if condition satisfies change the value in link ds
5. Again write the dataset into XML.

Hi,

I need help with the syntax for steps 2 and 3.

               For ???????
                If dsFuzeA.Fuze_ID = C1FuzeGrid.Columns(0).Value then
                r!PFuze_ID = dsFuzeA.PFuzeID
                Endif
                Next

For each drrow as datarow in dslunk.rows
For each prow as datarow in dsfuze.rows
If drrow(fuzeid) = prow(fuzeid) then
Drrow(fuzeid) = prow(pfuzeid)
Exit for ' no need to use if the if condition will be true for      multiple rows
End if
Next
