http://bugs.exim.org/show_bug.cgi?id=1600 --- Comment #7 from Prashant Joshi <[email protected]> 2015-03-20 04:52:44 --- Hi, In our application we used APIs of theses libs. I tried to search PCRE version on the older version but do not get. In older version we have very few files "pcre.c", "pgrep.c" & "study.c". We used function "pcre_complie" & "pcre_exec". In newer version we have a lot files and we used similar functions in our application. Applications are same for both versions of PCRE. No manipulations we have done in regex we directly called these functions. Regards Prashant Joshi Team Lead C/C++ (CA Engagement) HCL Technologies Ltd. A-8/9, Sector 60, Noida 201301, U.P.

What program are you using to handle that regex? PCRE is just a library, so it has to be called by another program. That program may well be pre-processing the regex before passing it to PCRE. > When I changed this regex to below regex it worked with 8.34: > Regex 2: > /Letzter Messwert[\s]+<\/th><td > class="ActualDataTableBody".*>[-+]?([0-9]*\.[0-9]+|[0-9]+)<\/td><td > class="ActualDataTableBody".*>[-+]?([0-9]*\.[0-9]+|[0-9]+)<\/td><td > class="ActualDataTableBody".*>[-+]?([0-9]*\.[0-9]+|[0-9]+)<\/td><\/tr><tr><th > scope="row" class="ActualDataTableRowLabel">Mittelwert/ > > Regex 1 is working with PCRE 0.2 but not with 8.34. > Regex 2 is working with PCRE 8.34. There never was a PCRE release 0.2, so I do not know what software you were using. The first release of PCRE was 0.91 (10-Sep-97). > Please let me know why is above behavior? Also Are there any other regex > changes which do not work with PCRE 8.34. It seems to me that whatever program you fed Regex 1 into was somehow processing it to allow for pairs of "" within the overall quotes, and was also handling the / delimiters within the pattern. I do not know what program might do that. Regex 2 looks like a regex delimited by / that is handled by a program that needs escaping internal / characters as \/ as you have done. The pcretest program will do this. So I ask again: what program are you actually passing your input to?
