I have input string to process of the format
xxx could by any combination of alphanumerics and underscore.
I am trying to capture the number between
item using regular expressions.
I have the regular expression
\\S*filters:(\\d+):item\\S* and it matches OK but I cannot work out how to extract the number.
The test code
Pattern myPattern = Pattern.compile('\\S*filters:(\\d+):item\\S*'); Matcher myMatcher = myPattern.matcher('aaaaab:filters:3:item:foo'); system.debug(myMatcher.matches()); system.debug(myMatcher.groupCount()); system.debug(myMatcher.group(0));
outputs the following:
true 1 aaaaab:filters:3:item:foo
as you see, the group has captured who whole string, not just the number which I want.
How do I get the number?
