Logged In: YES user_id=21627 Are you sure this is a bug in Python, and not in Alchemy? |

Logged In: YES user_id=76540 The code worked again after I downgraded to Python 2.2.3. If you like I can replicate in a shorter and includable code snippet (I'd need to pop 2.3 back on my box first though) |

Logged In: YES user_id=21627 It would definitely help if you could provide more detail on the nature of the failure. E.g. where did the DOM tree come from that Alchemy tries to invoke .normalize on, and what is self.childnodes in the place of the error. If you could instead submit a small example that allows reproduction of the error, that would help as well. |

Logged In: YES user_id=11375 I can trigger this exception by calling the normalize() method on a childless DOM node such as Text. A little script is attached. The question is: what should normalize() do for a class such as Text? Looking at the DOM Level 1 specification, .normalize() is actually part of the Element interface, not Node, so things like Text.normalize() wouldn't work at all. One solution: move normalize() onto the Element class. Possibly backwards-incompatible. Another solution: add a normalize() method to the Childless mix-in that raises an exception. |

This is still an issue with all Python versions, is there anybody who could take this on please? |

Well, we certainly can't going making any incompatible changes now, so I've opted to add an empty normalize() method to the Childless mix-in. This makes minidom a little more liberal than other DOM implementations, but I think that's OK. Committed to trunk in rev83152, and backported to 2.7 in rev83153. |
