Help with passing values to dataelement based on partial string


How d I modify the line below to look for part of AGD4, for example AGD4 contains data in the following format (XXXX-XX-XXXX) and I need to look for the mIddle value (-XX-) instead of the entire value of AGD4.

Group n By n.Element("AGD4").Value.substring (??)  Into agd4Group = Group

  '' Load the XML document to be summerized into memory
        Dim xdoc As XDocument = XDocument.Load(Application.StartupPath + "\AOP5.xml")

        '' Group the TableA nodes by AGD4 then get a string containing all the Country values order the Country values
        '' and return the groupings and summary string so that it can be inserted into the XML                                                                                                                      
        Dim results = (From n In xdoc.Descendants("AOP5C") Where n.Element("AGD4").Value <> "NA"
                       Group n By n.Element("AGD4").Value Into agd4Group = Group
                       Let sum = agd4Group.Select(Function(g) g.Element("COUNTRY").Value).OrderBy(Function(g) g).ToArray() _
                       From g In agd4Group _
                       Let summary = String.Join(",", sum) _
                       Select g, summary).ToList()

        '' Update the Summary node with the value of the summary string.                                                                                                                      
        results.ForEach(Sub(m) m.g.Element("CANMN").Value = m.summary)
        '' Save the document.                                                                                                                      
        xdoc.Save(Application.StartupPath + "\AOP5.xml")

How do I include Substring(AGD4, 5, 3) in Group n By n.Element("AGD4").Value.substring (??)  Into agd4Group = Group?

Hi Victor;

Have you tried it this way?

Group n By n.Element("AGD4").Value.SubString(5, 2)  Into agd4Group = Group

Which will make the grouping the two middle characters, YY, in the pattern XXXX-YY-XXXX.

I tied it but received error message

Range variable name can  be inferred only from a simple or qualified name with no arguments.

Hi Victor;

Because the grouping value is not a simple variable but an expression we need to give it a name.

Group n By Key = n.Element("AGD4").Value.SubString(5, 2)  Into agd4Group = Group
