正则表达式查找特定模式之间的所有字符串

Question

My input string can be one of the following lines:

Active App: Coffee (priority 34)

Active App: Hot Bread (priority 20)

Active App: Hot Baked Bread (priority 1)

etc...

In this case, instead of " Coffee ", it could be any string [a-zA-Z] (one or more words).

In " (priority 34) ", only the integer would change.

So how do I get the " Coffee "/" Hot Bread "/" Hot Baked Bread " from this line?

I am unable to properly handle the space between the words.

Here's a simple solution with python regex match() for you:

It disregards the part of the string after the application name that you want to capture. But that could be added, if important.

It will capture untill it sees a ( , and then later strip the trailing whitespace character from the string.

import re;

myStr = "Active App: Hot Baked Bread (priority 34)";
appStr = re.match("Active App: ([^\(]*)", myStr);
print(appStr.group(1).rstrip());

Here's a version that only captures the actual 'Active App' name, without the need to trim the string afterwards. And also checks to see that a match was found before printing it:

import re;

myStr = "Active App: Coffee Some (priority 34)";
appStringMatch = re.match("Active App: (.*)\s\(", myStr);
if appStringMatch:
    print(appStringMatch.group(1));
