This module provides primitives to build XML document as a Stream

Example

import XmlStream

rows = Stream.map(1..1000, fn i ->
  cells = Stream.map(1..40, fn j ->
    element("cell", %{row: to_string(i), column: to_string(j)}, content(to_string(i)))
  end)
  element("row", cells)
end)

stream!([declaration(), element("sheet", rows)], printer: XmlStream.Printer.Ugly)
|> Stream.into(File.stream!("sheet.xml"))
|> Stream.run

The body of an element could be either a eager Enumerable or a lazy one built via Stream module. The primitive functions like element/3, content/1 are used to build a tree structure where some nodes are not fully evaluated (child nodes could a stream). stream!/2 does a depth first traversal of the tree and runs the stream as necessary when it encounters one and returns a new stream of element type iodata
