本地文档中的网页有如下两段js代码会联网加载信息，将其注释掉后就好了

<link rel="stylesheet"  href="http://fonts.googleapis.com/css?family=Roboto:regular,medium,thin,italic,mediumitalic,bold" title="roboto">

<script src="http://www.google.com/jsapi" type="text/javascript"></script>

用以下java代码就可以批量注释

/*  * 去掉Android文档中需要联网的javascript代码  */  import java.io.BufferedReader;  import java.io.BufferedWriter;  import java.io.File;  import java.io.FileNotFoundException;  import java.io.FileReader;  import java.io.FileWriter;  import java.io.IOException;    public class FormatDoc {      public static int j = 1;        /**      * @param args      */      public static void main(String[] args) {            File file = new File("D:/docs/");          searchDirectory(file, 0);          System.out.println("OVER");      }        public static void searchDirectory(File f, int depth) {          if (!f.isDirectory()) {              String fileName = f.getName();              if (fileName.matches(".*.{1}html")) {                  String src = "<(link rel)[=]\"(stylesheet)\"\n(href)[=]\"(http)://(fonts.googleapis.com/css)[?](family)[=](Roboto)[:](regular,medium,thin,italic,mediumitalic,bold)\"( title)[=]\"roboto\">";                  String src1 = "<script src=\"http://www.google.com/jsapi\" type=\"text/javascript\"></script>";                  String dst = "";                  // 如果是html文件则注释掉其中的特定javascript代码                  annotation(f, src, dst);                  annotation(f, src1, dst);              }          } else {              File[] fs = f.listFiles();              depth++;              for (int i = 0; i < fs.length; ++i) {                  File file = fs[i];                  searchDirectory(file, depth);              }          }      }        /*      * f 将要修改其中特定内容的文件 src 将被替换的内容 dst 将被替换成的内容      */      public static void annotation(File f, String src, String dst) {          String content = FormatDoc.read(f);          content = content.replaceFirst(src, dst);          int ll = content.lastIndexOf(src);          System.out.println(ll);          FormatDoc.write(content, f);          System.out.println(j++);          return;        }        public static String read(File src) {          StringBuffer res = new StringBuffer();          String line = null;          try {              BufferedReader reader = new BufferedReader(new FileReader(src));              int i = 0;              while ((line = reader.readLine()) != null) {                  if (i != 0) {                      res.append('\n');                  }                  res.append(line);                  i++;              }              reader.close();          } catch (FileNotFoundException e) {              e.printStackTrace();          } catch (IOException e) {              e.printStackTrace();          }          return res.toString();      }        public static boolean write(String cont, File dist) {          try {              BufferedWriter writer = new BufferedWriter(new FileWriter(dist));              writer.write(cont);              writer.flush();              writer.close();              return true;          } catch (IOException e) {              e.printStackTrace();              return false;          }      }  }
