Question

I'm looking for a search with regex, which returns a list of all topics starting with a certain string and ending with "one uppercase letter and indefinitely lowercase letters but no more uppercase letter". I.e. "[A-Z][a-z]+$".

However, the appropriate regex search does not yeald the expected results:

%SEARCH{"^Host[A-Z][a-z]+$" regex="on" casesensitive="on" scope="topic" nosummary="on" noheader="on" nosearch="on" nototal="on" format="[[$topic]], "}%

returns an empty list. Whereas

%SEARCH{"^Host[A-Z][a-z]+" regex="on" casesensitive="on" scope="topic" nosummary="on" noheader="on" nosearch="on" nototal="on" format="[[$topic]], "}%

results in "HostAri, HostAriLog, HostAriConfig, HostCyber, HostCyberConfig, HostCyberLog, ".

What I want is "HostAri, HostCyber, ". How can I achieve that? .

Answer

For some reason "$" does not work to identify the end of the string. Use "^Host[A-Z][a-z]+[^A-Z0-9]" instead.

Thank you, but I tried all of the following regexps

• "^Host[A-Z][a-z]+[^A-Z0-9]"
• "^Host[A-Z][a-z]+[^A-Z0-9]*"
• "^Host[A-Z][^A-Z0-9]+"

I still get the HostSomething and the HostSomethingAndSomethingMoreWithCapitalLetters topics instead of only getting the HostSomething topics.

What else can I try?

You are right, this does not work. The "not" part in the regex does not apply if there is no required text after that. It looks like you need to search for some text in the topic that appears only in your HostSomething topics, but not in HostSomethingElse topics.

Therefore I change this question into a bug notice

Is fixed, see Codev.CantAnchorSearchREToEnd
