正则表达式从文本中提取工作体验

Question

我正在尝试创建一个通用正则表达式来从文本中提取工作体验。

考虑以下示例及其预期输出。

1）String string1= "My work experience is 2 years"

Output = "2 years" 

2）String string2 = "My work experience is 6 months"

Output = "6 months" 

我用正则表达式作为/[0-9] years/但它似乎并没有工作。

如果有人知道一般的正则表达式，请分享。

Answer 1

您可以使用交替：

String str = "My work experience is 2 years\nMy work experience is 6 months"; 
String rx = "\\d+\\s+(?:months?|years?)"; 
Pattern ptrn = Pattern.compile(rx); 
Matcher m = ptrn.matcher(str); 
while (m.find()) { 
    System.out.println(m.group(0)); 
} 

见IDEONE demo

输出：

2 years 
6 months 

或者，你也可以得到像3 years 6 months这样的字符串：

String str = "My work experience is 2 years\nMy work experience is 3 years 6 months and his experience is 4 years and 5 months"; 
String rx = "\\d+\\s+years?\\s+(?:and\\s*)?\\d+\\s+months?|\\d+\\s+(?:months?|years?)"; 
Pattern ptrn = Pattern.compile(rx); 
Matcher m = ptrn.matcher(str); 
while (m.find()) { 
    System.out.println(m.group(0)); 
} 

输出的another demo：

2 years 
3 years 6 months 
4 years and 5 months 

Answer 2

我建议使用此正则表达式：

String regex = "\\d+.*$"
