选取文件中内容编程或脚本编写
一个如 htm文件，里边有<head><body>，需要将<body>外的内容删除，<body>内的内容保留。。大家知道如何写么。。用java，或者批量出黎脚本
首先要保证<body>外的内容没有“<body>”，那读出整个文件到字符串，然后
str.substring(str.indexOf("<body>"),str.lastIndexOf("</body>")); 可否详细小小，真的不懂。。。。而且需要批量。。。
ps <body></body> 这两个tab也需要删除，只是留下 <body>内的内容。。 LZ会用Java读写文件吗？
假设会，读一个文件的内容到一个字符串，剩下的事情就是对字符串操作了，然后写回到文件即可。
至于批量，递归读一个文件夹里的文件即可 <body></body> 这两个tab也需要删除 ，请问如何删除 str.substring(str.indexOf("<body")+6,str.lastIndexOf("</body>"));
如果6不合适，试试7或5、或1 个人推荐一个最高效既解决方式：稳2楼帮手搞掂就得了～至于请食饭或者比现金就睇LZ嘎啦～横掂一个月稳甘多钱，都唔争在分D比校友啦～ 不耻上问:
如何批量，循环读一个目录内的文件阿。。。。
严重同意8#

import java.io.*;
public class Test {
public static void main(String[] args)throws Exception {
getFiles(new File("E:\\java"));
System.out.println(fileList.size());
}
private static List fileList=new ArrayList(159);
public static void getFiles(File file){
if (file.isDirectory()) {
// 获取目录下的文件和目录
File[] files = file.listFiles();
// 非空目录
if (files != null) {
for (int i = 0; i < files.length; i++) {
getFiles(files);
}
}
}else {
fileList.add(file);
System.out.println(file.getName());
}
}
}

LZ可以叫番碌碌宾宾佢地帮你写～哈哈哈～碌碌果D出手既话5分钟就帮你写好啦～ 你叫我去死算喇

str.substring(str.indexOf("<body")+6,str.lastIndexOf("</body>"));

这样有一个大问题
如果<body>标签是<body leftmargin="0" topmargin="0">这种形式呢?
<script>
var str="sdff<body leftmargin=/"0/" topmargin=/"0/">这种形式呢? 碌碌宾宾，好名字 /*
