请教正则式的写法，检查一行代码是否包括类似于“

[5803077]

检查若干个目录中的JSP，检查是否包括类似于
<%@ include file="head.jsp"%>
这样的代码。

一句话就是检查一个JSP是否引用了别的文件。

因为程序员的写法不一致，上面的写法可能是
<%@ include file="head.jsp"%>
<%@ include file = "head.jsp" %>
<%@ include file="head.jsp" %>
等等，所以想用正则式来检查。请问有谁能帮我下，我是正则式的新手。

谢谢!

请参考如下代码：patcher里面可以传入更多的参数，比如一个文件
[code=Java]
Pattern p = Pattern.compile("<%@\\s*include\\s*file=\"([^\"]*)\"%>");
Matcher m = p.matcher("<%@ include file=\"head.jsp\"%>");
while(m.find()){
System.out.println(m.group(1));
}
code]

    Pattern p = Pattern.compile("<%@\\s*include\\s*file=\"([^\"]*)\"%>");
    Matcher m = p.matcher("<%@      include     file=\"head.jsp\"%>");
    while(m.find()){
      System.out.println(m.group(1));
    }

^<%@\s*include\s*file="[^"]*"%>$

这个正则比2楼3楼多允许点空格

String regex="<%@\\s+include\\s+file\\s*=\\s*\"[^\"]*\"\\s*%>";
String input="<%@ include file = \"head.jsp\" %>";
if(Pattern.matches(regex, input)) {
	System.out.println("Matches!");
}

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Test {
	
	private static Pattern pattern = Pattern.compile("<%\\s*@\\s+include\\s+file\\s*=\\s*\"(.+?)\"\\s*%>");
	
	public static void main(String[] args) {
		String[] jsp = { 
					"<%@   include   file=\"head1.jsp\"%>",
					"<%@   include   file   =   \"head2.jsp\"   %>",
					"<%@     include     file=\"head3.jsp\"   %><%@     include     file=\"head4.jsp\"   %>" 
				};
		for(int i=0; i < jsp.length; i++) {
			Matcher matcher = pattern.matcher(jsp[i]);
			System.out.print(i+1);
			System.out.print(":");
			while(matcher.find()) {
				System.out.print("\t");
				System.out.print(matcher.group(1));
			}
			System.out.println();
		}
	}
}

LZ,是不是要读文件,再判断啊!
