Question: How to serialise/parse large xml file with KorIO

[multiport]

Hello,

I'm using KMM with Okio, and i'm triying to serialise/parse a large xml file, I see on https://docs.korge.org/korio/serialization/ how to parse a String but since my file is too large, im triying to parse the stream :

  val fileSystem = FileSystem.SYSTEM_TEMPORARY_DIRECTORY
  val path = fileSystem / "myfile.xml"
  // open a source stream
  val sourceFileRead= fileSystem2.source(path)
  // wrap stream with a buffer
  val fileopened = sourceFileRead.buffer()
  // read until end of file
  var line: String?
  var numLigne :Int =0
  while (fileopened.readUtf8Line().also { line = it } != null) {
      println(line)
      var xmlLine = line?.reader(line!!,numLigne)
      Xml.Stream.parse(xmlLine!!)  // <-- Not gonna work but i dont know how to do ?
  }

Thanks for your help if you have a solution

It is not posible right now. Xml streaming uses StrReader that was designed to use a String in memory. It was like that to be as fast as possible (no virtual methods, no suspension points, all in-memory).
The thing is that K/N have evolved a lot and now maybe the performance is much better, so might make sense now to create a String Reader that support streams without having the whole file in memory and make Xml to use it.
I have created a PR with a baby step towards it
