To clarify, #printToFileNamed: and company use CRLF on Windows and LF elsewhere. XMLWriter uses Pharo's LE by default (CR), but it will use the preferred LE of your platform (LF or CRLF) with #enablePlatformSpecificLineBreak, LF when canonical XML (https://www.w3.org/TR/xml-c14n) is enabled, or whatever LE you want with #lineBreak:. You can use #printToFileNamed:beforeWritingDo: with a block that sends #lineBreak: to the writer argument to get a custom LE when printing a DOM tree to a file. > Overall this was a nice win. > It cleaned up my method to save the file and reduced 7 lines to 2. > Nice. :) > > Thanks. > > Jimmie > > > > On 09/15/2017 09:29 AM, monty wrote: > > If you want to write a DOM tree to a file, send #printToFileNamed: (or a > > related message like #canonicallyPrintToFileNamed: or > > #printToFileNamed:beforeWritingDo:) to the root.
