F# XmlProvider and parsing collection - f#

Question

I have a question. I have a simple configuation in a file that looks:
<configuration>
<Protocol Version="1" />
<RequestParameters>
<ModuleIdentyfication Interval="500" />
<SectionIdentification Interval="500" />
</RequestParameters>
</configuration>
Config file is in the same folder as app so my reading module looks like:
[<Literal>]
let private cabinetConfigFilename : string = "cabinet.config";
type Communication = XmlProvider<cabinetConfigFilename>
let GetConnectionConfiguration : Async<Option<ServiceConfiguration>> =
async {
let assemblyPathInfo = FileInfo(Assembly.GetEntryAssembly().Location);
let configurationFilePath = Path.Combine(assemblyPathInfo.DirectoryName, cabinetConfigFilename);
let root = Communication.Parse((File.ReadAllTextAsync(configurationFilePath) |> Async.AwaitTask |> Async.RunSynchronously))
try
let protocolVersion : uint8 = uint8 root.Protocol.Version
let requestParameters = Communication.Parse (string root.RequestParameters)
for param in requestParameters do printf " - "
return Some (ServiceConfiguration(protocolVersion))
with
| :? ArgumentNullException -> logger.Error("No IP address was given"); return None;
| :? FormatException -> logger.Error("IP address incorrect format was given"); return None
}
So I have no problem, with getting Protocol.Version, but problem is with parsing that RequestParameters, I am getting a whole XProvider object but I can not use it as seq. I tried to do it as is written in https://fsharp.github.io/FSharp.Data/library/XmlProvider.html in Types for multiple simple elements section. Is there a way to cast it to sequence.

Answer 1

The easiest (read: laziest) way if you just have these two types, is to simply double up the sample:
<RequestParameters>
<ModuleIdentification Interval="500" />
<ModuleIdentification Interval="500" />
<SectionIdentification Interval="500" />
<SectionIdentification Interval="500" />
</RequestParameters>
Now you can access the array of elements using:
RequestParameters.ModuleIdentifications and RequestParameters.SectionIdentifications.
A better way to go about this is to generate an XSD for your XML,
and use the type provider with
FSharp.Data.XmlProvider<Schema = ...>
