问题描述

我有一个50MB的XML文件。我想将其转换为CSV文件，但大多数方法我发现耗尽服务器内存。

I have a 50MB XML file. I want to convert it to a CSV file, but most methods I have found exhaust the server memory. Is there a good way to do this using a stream method such as XMLreader.

推荐答案

您想要使用 XmlReader 解析XML，因为它作为一个基于事件的解析器 - 例如。它不会将所有内容加载到内存中，而是在通过输入文件前进行读取。

You'd want to use XmlReader to parse the XML, as it works as an event based parser - Eg. it doesn't load everything into memory, but rather reads as it advances through the input file.
