[英]Regex after a special character in Java
I am using regex in java to get a specific output from a list of rooms at my University. 我在Java中使用正则表达式从大学的房间列表中获取特定输出。
A outtake from the list looks like this: 清单中的支出如下所示:
I want to get the value that comes between the colon and the parenthesis. 我想获得介于冒号和括号之间的值。
The regex I am using at the moment is: 我目前使用的正则表达式是:
pattern = Pattern.compile("[:]([A-Za-z0-9ÆØÅæøå-]+)");
matcher = pattern.matcher(room.text());
I've included ÆØÅ, because some of the rooms have Norwegian letters in them. 我包括了ÆØÅ,因为其中一些房间里有挪威字母。
Unfortunately the regex includes the building code also (eg "A55") in the output... Comes out like this: 不幸的是,正则表达式还在输出中包括了建筑代码(例如“ A55”)...像这样出来:
A55
A55
A55
:G260
:G292
:G316
Any ideas on how to solve this? 关于如何解决这个问题的任何想法?
The problem is not your regular expression. 问题不在于您的正则表达式。 You need to reference group(
1
) for the match result. 您需要引用group(
1
)作为匹配结果。
while (matcher.find()) {
System.out.println(matcher.group(1));
}
However, you may consider using a negated character class instead. 但是,您可以考虑使用否定字符类。
pattern = Pattern.compile(":([^)]+)");
You can try a regex like this : 您可以尝试这样的正则表达式:
public static void main(String[] args) {
String s = "(HDS:FLØYEN) Fløyen (appendix)";
// select everything after ":" upto the first ")" and replace the entire regex with the selcted data
System.out.println(s.replaceAll(".*?:(.*?)\\).*", "$1"));
String s1 = "ODO:PC-STUE) Pulpakammeret (PC-stue)";
System.out.println(s1.replaceAll(".*?:(.*?)\\).*", "$1"));
}
O/P : O / P:
FLØYEN
PC-STUE
Can try with String
Opreations as follows, 可以尝试使用
String
Opreations,如下所示:
String val = "(HDS:FLØYEN) Fløyen (appendix)";
if(val.contains(":")){
String valSub = val.split("\\s")[0];
System.out.println(valSub);
valSub = valSub.substring(1, valSub.length()-1);
String valA = valSub.split(":")[0];
String valB = valSub.split(":")[1];
System.out.println(valA);
System.out.println(valB);
}
Output : 输出:
(HDS:FLØYEN)
HDS
FLØYEN
import java.util.regex.Matcher; 导入java.util.regex.Matcher; import java.util.regex.Pattern;
导入java.util.regex.Pattern;
class test { public static void main( String args[] ){ 类测试{public static void main(String args []){
// String to be scanned to find the pattern.
String line = "(HDS:FLØYEN) Fløyen (appendix)";
String pattern = ":([^)]+)";
// Create a Pattern object
Pattern r = Pattern.compile(pattern);
// Now create matcher object.
Matcher m = r.matcher(line);
while (m.find()) {
System.out.println(m.group(1));
}
} } }}
