每条记录的XML解析 [英] XML parsing per record
问题描述
我想解析一个非常大的（2.4 gig）XML文件（生物信息学课程:)）
但我不知道如何做到这一点。我看到的大多数内容都会立即读取整个xml
文件。那是不可能在这里工作的。
所以我想一次解析一个XML文件，然后能够
到将信息存储在另一个对象中。
我该怎么做？

I want to parse a very large (2.4 gig) XML file (bioinformatics ofcourse :))
But I have no clue how to do that. Most things I see read the entire xml
file at once. That isn''t going to work here ofcourse.
So I would like to parse a XML file one record at a time and then be able
to store the information in another object.
How should I do that?
Thanks in advance,

A total newbie to python by the way.

Out of curiousity, why is the data stored in a XML file?
XML is not known for its efficiency....
