Python 中 minidom 的内存错误

我在 Python 中遇到了带有 minidom 解析器的 MemoryError 。 我正在读取 8000 个小文件（大部分小于 50 Kb），在读取 2500 个后出现此错误...`

Traceback (most recent call last): 

 File "C:\eclipse\plugins\org.python.pydev.debug_2.4.0.2012020116\pysrc\pydevd.py", line 1307, in <module>

MemoryError

有没有人可以建议一个“无内存泄漏”解析器？

我还建议使用内置的 cElementTree。 Minidom 有很多问题：/

除此之外，lxml 也相当不错，并且具有更多功能。
