Hi - very new to regexes - so apologies

 I'm trying to catch data which can be optional after the first entry

i.e. 

Test cases

<one><end>

<one> | <two><end>

<one> | <two> | <three><end>

gives answer groups as follows

one

one two

one two three

 

and so on.

There is a finite number of optionals but the number is unknown.

I tried 

<([^>]*)>( | <([^>]*)>)*?<end>

but I think I'm getting caught out by using the incorrect identifier to get the contents between the <> AND also being too 'greedy':-(

Could someone please give me advice on the best way to approach this ?

Cheers

 

Hi,

Pattern :

 

(I have to use a screenshot since this forum messes up tag like sequences)

Replace With :

$1

Using C# (state your language if it can help you)

resultString = Regex.Replace(subjectString, @"<(.*?)>.*?(\||<end>)", "$1", RegexOptions.Singleline);

 Given this as input :

 <one><end>

<one> | <two><end>

<one> | <two> | <three><end>

 It will produce this output :

one

one two

one two three
