Dear Regex Guru, I am trying to use REGEX_SEARCH algorithm to match lookahed subexpression. Search in the folowing strings (see below) using expression like: /exchange/test/(?!Drafts)/a.EML/b.png fails /exchange/test/Drafts/a.EML/b.gif /exchange/test/Inbox/a.EML/b.png /exchange/test/Inbox/a.EML/b.gif /exchange/test/Drafts/a.EML/b.png At the same moment I can suceesfully search using the expression: /exchange/test/Inbox/a.EML/b.(?!png).
From online documentation I realize that regex supports lookahed search. Please help me understand what I am doing wrong.
P.S. It is tested with the program closely modeled from example provided for regex_search. Thank you for your help. Yan Belinky Senior Software Engineer. Whale Communications, LTD.
