求XML达人帮忙！我有一个860MB左右的XML文件，要怎么分割它？
新手刚刚接触这方面的问题 请教一下大侠们 帮帮忙 这个XML文件太大了 我用notepad打开后就是未响应 现在不是很清楚里面的具体结构 然后向把XML文件先分成几个小文件一个一个打开 看结构 不然太卡了 sax和DOM到底怎么用 网上搜了一个4种方法区别 看了以后还是不太懂 我用的DOM4J解析器 也可以使用sax方法么？？好多疑问 求教！！

我这可以通过 python 把你这个文件 分割成一份一份的可以帮助你查看xml的内容

Python code

#!C:\Python27 python# -*-  coding:UTF-8 -*-import os,syssize = 80*1024*1024partnum = 0input = open("c:\\test.zip",'rb')text = input.read(size)while text:    partnum = partnum + 1    fileoutput = open("c:\\ttt\\test%04d"%partnum+".zip",'wb')    fileoutput.write(text)    fileoutput.close()    text = input.read(size)input.close()

试试这个,估计也不可能快:
Java code
