麻烦大虾给出具体代码。
如原来的格式是<html><body>ddfd</body></html>这是从数据库里查询出的内容，

public String formatHTML(String input)
{ if(input==null||input.length() ==0){
return input;}
//建立一个Stringbuffer 来处理输入的数据
StringBuffer buf=new StringBuffer(input.length() +6);
char ch=' ';
//处理非法字符穿
for (int i=0;i<input.length() ;i++){
ch=input.charAt(i);
if(ch=='<') {
buf.append("<");
}
if (ch=='>'){
buf.append(">");
}
if (ch=='\n'){
buf.append("<br>");
}
if(ch=='\''){
buf.append("´");
}
if (ch==' '){
buf.append(" ");
}
else
{
buf.append(ch);
}
}
return buf.toString();
}

可以给我结帐了

函数：
<%!
public String replace(String line,String ch,String rep)
{
int i = line.indexOf(ch);
StringBuffer sb = new StringBuffer();
if (i == -1)
return line;
sb.append(line.substring(0,i) + rep);
if (i+ch.length() < line.length())
sb.append(replace(
line.substring(i+ch.length(),line.length()),
ch,
rep));
return sb.toString();
}
%>

////举例
try
{
fis = new FileInputStream(file);
BufferedReader br = new BufferedReader(
new InputStreamReader(fis));
String line;
while ((line = br.readLine()) != null)
{
line = replace(line, "&", "&");
line = replace(line, "<", "<");
line = replace(line, ">", ">");
out.println(line);
}
fis.close();
}
catch (IOException e)
{
out.println("IOException: " + e.getMessage());
}
