Howdy I ran into a difference between Python on Windows XP and Linux Fedora 6.
Writing a dom to xml with minidom works on Linux. It gives an error on XP if there is an empty namespace. The problem was handled in CVS a while ago. http://mail.python.org/pipermail/xml-sig/2003-October/009904.html Here is an example on XP Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from xml.dom.minidom import parseString >>> doc = parseString('<root>value</root>') >>> doc.toxml() u'<?xml version="1.0" ?><root>value</root>' >>> doc = parseString('<root xmlns="">value</root>') >>> doc.toxml() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\tools\Python25\lib\xml\dom\minidom.py", line 45, in toxml return self.toprettyxml("", "", encoding) File "C:\tools\Python25\lib\xml\dom\minidom.py", line 57, in toprettyxml self.writexml(writer, "", indent, newl, encoding) File "C:\tools\Python25\lib\xml\dom\minidom.py", line 1744, in writexml node.writexml(writer, indent, addindent, newl) File "C:\tools\Python25\lib\xml\dom\minidom.py", line 809, in writexml _write_data(writer, attrs[a_name].value) File "C:\tools\Python25\lib\xml\dom\minidom.py", line 299, in _write_data data = data.replace("&", "&").replace("<", "<") AttributeError: 'NoneType' object has no attribute 'replace' and it's working on Linux Python 2.4.4 (#1, Oct 23 2006, 13:58:00) [GCC 4.1.1 20061011 (Red Hat 4.1.1-30)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from xml.dom.minidom import parseString >>> doc = parseString('<root>value</root>') >>> doc.toxml() u'<?xml version="1.0" ?>\n<root>value</root>' >>> doc = parseString('<root xmlns="">value</root>') >>> doc.toxml() u'<?xml version="1.0" ?>\n<root xmlns="">value</root>' Should the library on XP be updated?
