Python 2.6 xml.dom.ext对象缺失？

我正在使用我在线上发现的脚本，通过解析某些XML来转换某些文件。该脚本是在Python 2.6中构建的，它使用了一个模块，我相信在我通过网络阅读的内容中并不包含2.6。我想知道是否有解决办法。我得到的错误是：Python 2.6 xml.dom.ext对象缺失？

没有模块名称EXT

在下面的脚本，我认为这是越来越挂在进口xml.dom.ext，它似乎只在最后对使用该对象PrettyPrint（查看最后一个Try语句）我想知道在2.6中是否有解决这个问题的方法？我似乎无法找到一个模块，其中包含我可以导入的EXT对象。

的脚本是：

的xml.dom.ext模块从未被添加到Python标准库。

它只是PyXML distribution的一部分，但几年来没有看到任何更新，我怀疑它仍然可以在Python 2.6上工作。

相反，只需拨打文档minidom命名.toprettyxml()方法漂亮打印输出，然后写数据到文件：

f.write(doc.toprettyxml())
