storme Posted April 20, 2012 Share Posted April 20, 2012 G'day allI'm extracting version information from a web site. However the field comes out like this"{Program name containing spaces} {Version number}[ beta {beta number]"Originaly I was ignoring beta vereions so just ignored it and used this line to get the version number$sCurrentVersion = StringMid($asCurrentVersion[0], StringInStr($asCurrentVersion[0], " ", 0, -1) + 1)However for something like this "Firefox 12.0 Beta 6" I get a version of 6 when I'd like "12.0 Beta 6"Now I could write up several lines ofr code to stripe parts from the line till I get what I want. However, it would get very messy and I'm sure the regex gurus have a simple (complicated looking) single line that does all the work very elegantly. It has to handle situations like these:Firefox 12.0 Beta 6 Version = 12.0 Beta 6Google Chrome 19.0.1084.30 Beta Version = 19.0.1084.30 BetaACDSee 14.2.157 Version = 14.2.157Flash Player 11.3.300.231 Beta 2 (IE) Version = 11.3.300.231 Beta 2Google Chrome 19.0.1084.30 Beta Version = 19.0.1084.30 BetaThanks in advance for any help!John Morrison Some of my small contributions to AutoIt Browse for Folder Dialog - Automation SysTreeView32 | FileHippo Download and/or retrieve program information | Get installedpath from uninstall key in registry | RoboCopy function John Morrison aka Storm-E Link to comment Share on other sites More sharing options...

storme Posted April 20, 2012 Author Share Posted April 20, 2012 $version = StringRegExp($text, "^(?:.+?)(?=\d+\.)(.*)$", 1) Thanks Mate! I did ask for an Expert and I got one. I did give it a fo myself nad had some of the right elements but couldn't get it to work. If you don't mind I'm trying to understand the regex and this is what I've got so far. ^ - Start of line (?:.+?) - NON capture group 1 or more characters (?= - Can'f find this one in the AutoIT help file?? But I'm guessing it's a look a head \d+ - One of more digits \. - Would seem to indicate a full stop (period) ??WHY?? ) - end of look ahead (.*) - Capture ALL $ - to end of line OK I get what the period was for now. To look for at least one . in a version number. However there are a few that don't have them so I'll have to remove that to allow for them. Sorry I didn't have one in the examples. So teh new version should look like this. $version = StringRegExp($text, "^(?:.+?)(?=\d+)(.*)$", 1) The only thing it didn't do was remove the (ie) from the end of the "Flash Player 11.3.300.231 Beta 2 (IE)" version but that I can live with and I think the regex would get complicated to do that one and still pick up everything else.

GEOSoft Posted April 20, 2012 Share Posted April 20, 2012 this might work a bit better$version = stringregexp($text, "^(?:.+?)(?=[d.]+)(.*)$", 1) George Question about decompiling code? Read the decompiling FAQ and don't bother posting the question in the forums.Be sure to read and follow the forum rules. -AKA the AutoIt Reading and Comprehension Skills test.*** The PCRE (Regular Expression) ToolKit for AutoIT - (Updated Oct 20, 2011 ver:3.0.1.13) - Please update your current version before filing any bug reports. The installer now includes both 32 and 64 bit versions. No change in version number. Visit my Blog .. currently not active but it will soon be resplendent with news and views. Also please remove any links you may have to my website. it is soon to be closed and replaced with something else. "Old age and treachery will always overcome youth and skill!"

storme Posted April 21, 2012 Author Share Posted April 21, 2012 this might work a bit better $version = stringregexp($text, "^(?:.+?)(?=[d.]+)(.*)$", 1) Unless I made a mistake [d.] means (any digit) or . Period. But wouldn't that mean that if a program name contains a . then it would mess up? eg "My great .net updater 4.0" : Version = ".net updater 4.0" As all versions I have found start with a digit I think I'll leave periods out of it completly. BUT a big thanks for the suggestion.
