[oXygen-user] regular expression problem

[Toufexis Notis]

Dear all,

I am using oxygen 9 for MacOS X. From time to time I have the  
following problems with find & replace while using regular  
expressions. I search for

<l>(.+)(\d+)(</l>) (in a TEI-encoded verse text find numbers at the  
end of verse before the closing tag)

and want to replace it with

<l n="$2"> $1 ($2) $3 (copy the numbers as n attribute within the tag  
and put also before the closing tags within parentheses)

Strangely, from time to time only the first digit is being copied  
with the replace function, although all digits are being highlighted  
with the search function. I have not been able to figure out when  
this happens. The same happens also if instead of (\d+) I use (\d{1,4}).

Any ideas what is causing this and how it can be fixed?

Best wishes,
Notis
