处理大型xml文件 [英] Processing large xml files

问题描述

我有一个包含许多子元素的大型xml文件。我想能够运行一些xpath查询。我尝试在java中使用vtd-xml，但有时会出现outofmemory错误，因为xml非常大以适应内存。是否有另一种处理如此大的xml的方法。

推荐答案

尝试 http://code.google.com/p/jlibs/wiki/XMLDog

它使用sax执行xpath而不创建xml文档的内存表示。

it executes xpaths using sax without creating in-memory representation of xml documents.
