New submission from Mark Summerfield <m...@qtrac.eu>: If you read in an XML file using xml.etree.ElementTree.parse() and then write it out again using xml.etree.ElementTree.write() what is written may not be the same as what was read. In particular any XML declaration and processing instructions are stripped.
It seems to me that the parser should at least preserve any declaration and processing instructions so that reading and writing match up. Here's an example: Python 3.1.2 (r312:79147, Jul 15 2010, 10:56:05) [GCC 4.4.4] on linux2 Type "copyright", "credits" or "license()" for more information. >>> file = "control-center.xml" >>> open(file).read()[:500] '<?xml version="1.0" encoding="utf-8"?>\n<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN" "http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd"; [\n<!ENTITY VERSION "1.5.7">\n]>\n<article id="index" lang="en_GB">\n \n <articleinfo>\n <abstract role="description">\n <para>The GNOME Control Centre provides a central place for the user to setup their GNOME experience.
