Python2.6中ElementTree的iter（）等效项 [英] ElementTree's iter() equivalent in Python2.6

问题描述

我有ElementTree的这段代码，可与Python 2.7很好地配合。
我需要获取 X / Y节点下所有名称为 A的节点。

I have this code with ElementTree that works well with Python 2.7. I needed to get all the nodes with the name "A" under "X/Y" node.

from xml.etree.ElementTree import ElementTree

verboseNode = topNode.find("X/Y")
nodes = list(verboseNode.iter("A"))

当我尝试使用Python 2.6运行它时，出现了此错误。

However, when I tried to run it with Python 2.6, I got this error.

ionCalculateSkewConstraint.py", line 303, in getNodesWithAttribute
    nodes = list(startNode.iter(nodeName))
AttributeError: _ElementInterface instance has no attribute 'iter'

看起来像Python 2.6 ElementTree的节点
如何使用Python 2.6实现iter（）？

It looks like that Python 2.6 ElementTree's node doesn't have the iter(). How can I implement the iter() with Python 2.6?

推荐答案

请注意， iter 在Python 2.6（甚至2.5）中可用-否则，文档），因此您实际上不需要替换。

Note that iter is available in Python 2.6 (and even 2.5 - otherwise, there'd be a notice in the docs), so you don't really need a replacement.

但是，您可以使用 findall ：

You can, however, use findall:

def _iter_python26(node):
  return [node] + node.findall('.//*')
