I didn't pay attention to this previously. But I just noticed that using
#printToFileNamed: preserved the DOM tree's original line ending where
as previously I had to insure the the XMLWriter #lineEnding was changed
from defaultLineEnding to canonicalLineEnding. The original document
used LF and not CR.
Overall this was a nice win.
It cleaned up my method to save the file and reduced 7 lines to 2.
Nice. :)
Thanks.

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. See the
XMLNode "printing" category for more. This will automatically encode the file with
the encoding the XMLDocument>>#encoding attribute specifies (if recognized), and it's
portable across Pharo, Squeak, and GemStone. Use #parseFileNamed:/#onFileNamed: to get portable
automatic file decoding when parsing.

Subject: [Pharo-users] Writing XML
Hello,
I am attempting to read and write an XML document.
Currently I have parsed the document successfully. I have basic
navigation and have learned how to modify the XMLDocument.
Now I want to write the modified document back to the file system.
What I have tried so far is:
writer := XMLWriter new.
xmldoc document writeXMLOn: writer.
writer stream.
f := File openForWriteFileNamed: '/home/jimmie/xmldoc.xml'.
f nextPutAll: (writer write contents).
f flush.
f close.
It does write an xml document to the file system. However, it has
exploded in size. The original is 28mb and is in UTF-8. The newly
written file is 112mb and is UTF-32.
I do not know why the change in encoding or how to correct or manually
set the encoding.
Any help in understanding how to correctly write an XML document that I
have read and minimally modified would be greatly appreciated.
Thanks.
Jimmie
