请问python中如何通过判断是否存在指定tag,截取tag中包含的内容

Question

//FEATURE_COMMON @{

import java.util.List;
public class Test{
List<String> list=new ArrayList<String>();
}

//@} FEATURE_COMMON

//FEATURE_PLAY_STATE @{
public int count(){
return 20;
}

//@} FEATURE_PLAY_STATE

//FEATURE_PLAY_MEDIA @{

public int sum() {
return 200;
}
//@} FEATURE_PLAY_MEDIA

//FEATURE_COMMON @{
}
//@} FEATURE_COMMON

通过判断Tag(//FEATURE_COMMON @{等)是否存在，取出这样一对//FEATURE_COMMON @{ .... //@} FEATURE_COMMON 中的内容

Answer 1

>>>s=""//FEATURE_COMMOAN @{................""">>> import re>>> reg=re.compile(r"//FEATURE_COMMON\s+@\{(.*?)//@\}\s+FEATURE_COMMON",re.DOTALL)>>> reg.findall(s)
