Stylesheet for converting or exporting FileMaker's FMPXMLRESULT to struct and enum in Swift 4

FileMaker FMPXMLRESULT to Swift 4 Struct

/FMPXMLRESULT/METADATA/FIELD/@TYPE	Swift 4
TEXT	String
DATE	Date
TIMESTAMP	Date; ideally there should be some sort of Postgres' timestamptz implementation for this
TIME	Date
NUMBER	Float; yet in several cases mapping this to Int would be less insane, though I'd love to have Postgres' Numeric for this.

Sample output done in shell on a Mac; you might as well make a FileMaker( FileMaker 5 and up ) XML export script if you need to do this frequently:

$ xsltproc fmpxmlresult2swift4Struct.xslt YourTable.fmpxmlresult.xml

struct Tablename {
  let itemID: Float
  let itemUUID: String
  let itemName: String
  let itemDescription: String
}

$ xsltproc fmpxmlresult2swift4Enum.xslt YourTable.fmpxmlresult.xml

enum Tablename {
  case itemID( Float )
  case itemUUID( String )
  case itemName( String )
  case itemDescription( String )
}

var TablenameitemID = Tablename.itemID("test")
var TablenameitemUUID = Tablename.itemUUID("test")
var TablenameitemName = Tablename.itemName("test")
var TablenameitemDescription = Tablename.itemDescription("test")

switch Tablename {
  case .itemID
    print("Output: \(itemID)")
  case .itemUUID
    print("Output: \(itemUUID)")
  case .itemName
    print("Output: \(itemName)")
  case .itemDescription
    print("Output: \(itemDescription)")
}

One would typically change Float to Int; and make a separate UUID datatype based on string for this use case.

This is an XSLT stylesheet to convert from FileMaker's fmpxmlresult to Swift 4's Enum and Struct for Cocoa[Touch] development saves me some typing, no records involved. This has no use if you prefer to retype stuff.

This is a PoC( Proof of Concept )

Works fine with all field types; however number field will have to be manually post validated for now.

Note that adding a layout name in the FMPXMLRESULT export; before translating using this XSLT, will make the output more complete. FileMaker does usually skip layout name on exports, if you know when FileMaker actually outputs the layout name, please enlighten me.

How to use this file in terminal

xsltproc fmpxmlresult2swift4Struct.xslt YourTable.fmpxmlresult.xml > YourTablesStruct.snippet.swift

xsltproc fmpxmlresult2swift4Enum.xslt YourTable.fmpxmlresult.xml > YourTablesEnum.snippet.swift
