问题 I'm feeling very silly for not being able to figure this one out, but I just cant figure it. I need to replace a regex string with a pattern, I found two examples of doing it, but they honestly left me more confused than ever. This is my current attempt: $string = '26 14:46:54",,"2011-08-26 14:47:02",8,0,"BUSY","DOCUMENTATION","1314370014.18","","","61399130249","7466455647","from-internal","""Oh Snap"" <61399130249>","SIP/1037-00000014","SIP/CL-00000015","Dial","SIP/CL/61436523277,45","2011

MySQL REGEXP usage within Boolean Match/Against

阅读更多关于 MySQL REGEXP usage within Boolean Match/Against

问题 I have the following MySQL query: SELECT title, description FROM some_table WHERE MATCH (title,description) AGAINST ('+denver (REGEXP "[[:<:]]colorado[s]*[[:>:]]")' IN BOOLEAN MODE); the "regexp" here looks for a "complete word" colorado (with or without the ending "s"). I want to actually select only those rows that have ("denver") AND ("colorado" or "colorados"). But I cannot put a "+" for the REGEXP. I tried but got 0 results, although there are rows in the table that match the requirement

Most efficient way to match (a few) strings in C?

阅读更多关于 Most efficient way to match (a few) strings in C?

问题 Our system needs to accept user input from a terminal and match against a few known keyword strings (maybe 10). We don't have the space/computrons to do regexp etc., code needs to be tiny & quick. Now, the nasty way to do this is: // str is null-terminated, assume we know it's safe/sane here if(!strncmp(str,"hello",5) { do_hello(); } else if(!strncmp(str,"world",5) { do_world(); } else { meh(); // Wasn't a match } So, after a bit of googling & reading I'm being convinced that a nicer way is

问题 I'm working with MATLAB's regexp() and I'm trying to find a regular expression that would match only file names containing Cyto but not CytoBlue . My problem is that the file names look either like Texture_Variance_Cyto_4_90 and Texture_Variance_CytoBlue_4_90 , or HIST_9BinsHistBin7_Cyto and HIST_9BinsHistBin7_CytoBlue . If I just try to match Cyto , I also capture all the files containing CytoBlue . If I try to match Cyto_ , I miss the file names where Cyto is the last element. I guess I'd

问题 I have this regex code I use in my code: pattern = re.compile('\d{3,4}(\/?)(\d{6,6})') m= pattern.match('0481/987421') if m: print "yes" else: print "no" It's a regex that should work for phonenumbers like this: dddd/dddddddd so first 3 or 4 digits, then a slash or not and then exactly 6 digits. It works fine, for example 21/484135 doesn't work and other wrong things also don't work. But the problem of this regex is, when my first characters are right and I type anything random behind it it
