Knight Posted July 20, 2005 Share Posted July 20, 2005 I have a text file that is around 20,000 lines long and has alot of symbols and I want to remove every character that is not alpha-numeric or standard punctuation. I have tried different approaches and it always messes up. Any ideas or help would be greatly appreciated. -k Link to comment Share on other sites More sharing options...
flyingboz Posted July 20, 2005 Share Posted July 20, 2005 (edited) I have a text file that is around 20,000 lines long and has alot of symbols and I want to remove every character that is not alpha-numeric or standard punctuation. I have tried different approaches and it always messes up. Any ideas or help would be greatly appreciated.-k<{POST_SNAPBACK}>1. determine ascii desired codes. 2. look at manual to determine how to find ascii value of code. 3. read file. 4. parse file 1 char at a time. 5. if char > lowest -1 and < greatest + 1 then writegoodchar to file repeat while there are still chars to process. refer to manual for instructions having to do w/ fileopen, filewrite, fileread, select ..case..endselectThe rest is left as an exercise for the student...

MSLx Fanboy Posted July 20, 2005 Share Posted July 20, 2005 $file1 = fileopen('mytext.txt', 0) $file2 = fileopen('mynew.txt', 2) $text = fileread($file1, 1) If @error Then Exit If StringIsAlNum($text) Then FileWrite($file2, $text) Also, if you're going to use that, make sure to add the OnAutoItExit Func to close the files Writing AutoIt scripts since _DateAdd("d", -2, _NowCalcDate()) Link to comment Share on other sites More sharing options...

I haven't tested, sso I'm not sure... If so, you may need to FileReadLine, parse the line character by character and then FileWriteLine...Dale Free Internet Tools: DebugBar, AutoIt IE Builder, HTTP UDF, MODIV2, IE Developer Toolbar, IEDocMon, Fiddler, HTML Validator, WGet, curl MSDN docs: InternetExplorer Object, Document Object, Overviews and Tutorials, DHTML Objects, DHTML Events, WinHttpRequest, XmlHttpRequest, Cross-Frame Scripting, Office object model Automate input type=file (Related) Alternative to _IECreateEmbedded? better: _IECreatePseudoEmbedded Better Better?
