You can use String#replaceAll() with a pattern of ^\”|\”$ for this. E.g. string = string.replaceAll(“^\”|\”$”, “”); To learn more about regular expressions, have al ook at http://regular-expression.info. That said, this smells a bit like that you’re trying to invent a CSV parser. If so, I’d suggest to look around for existing libraries, such as OpenCSV.
The substr() function will probably help you here: $str = substr($str, 1); Strings are indexed starting from 0, and this functions second parameter takes the cutstart. So make that 1, and the first char is gone.
UPDATE: A quick benchmark showed that Matt’s own adaption, based on Max’ & mine, performs best. @implementation NSString (TrimmingAdditions) – (NSString *)stringByTrimmingLeadingCharactersInSet:(NSCharacterSet *)characterSet { NSUInteger location = 0; NSUInteger length = [self length]; unichar charBuffer[length]; [self getCharacters:charBuffer]; for (location; location < length; location++) { if (![characterSet characterIsMember:charBuffer[location]]) { break; } } return [self substringWithRange:NSMakeRange(location, length … Read more

You can do this with my mp4parser library. Have a look at the ShortenExample it does exactly what the name suggests. Since the library cannot re-encode the video it can only cut the video at I-frames. So the points in time where you can make a cut are quite coarse. On Android 4.1 you can … Read more
Since you cannot extend string.Trim(). You could make an Extension method as described here that trims and reduces whitespace. namespace CustomExtensions { //Extension methods must be defined in a static class public static class StringExtension { // This is the extension method. // The first parameter takes the “this” modifier // and specifies the type … Read more
Late to the party but… There is no need for iteration through cells/values nor a recursive function to search and replace multiple spaces in a range. Application.Trim wil actually take care of multiple spaces between words (and will trim leading/trailing spaces) leaving single spaces in between words intact. The great thing about it, is that … Read more
Apache Commons has a great StringUtils class (org.apache.commons.lang.StringUtils). In StringUtils there is a strip(String, String) method that will do what you want. I highly recommend using Apache Commons anyway, especially the Collections and Lang libraries.
Using a combination of SUBSTR, INSTR, and NVL (for strings without an underscore) will return what you want: SELECT NVL(SUBSTR(‘ABC_blah’, 0, INSTR(‘ABC_blah’, ‘_’)-1), ‘ABC_blah’) AS output FROM DUAL Result: output —— ABC Use: SELECT NVL(SUBSTR(t.column, 0, INSTR(t.column, ‘_’)-1), t.column) AS output FROM YOUR_TABLE t Reference: SUBSTR INSTR Addendum If using Oracle10g+, you can use regex … Read more
Taken from this answer here: https://stackoverflow.com/a/5691567/251012 – (NSString *)stringByTrimmingTrailingCharactersInSet:(NSCharacterSet *)characterSet { NSRange rangeOfLastWantedCharacter = [self rangeOfCharacterFromSet:[characterSet invertedSet] options:NSBackwardsSearch]; if (rangeOfLastWantedCharacter.location == NSNotFound) { return @””; } return [self substringToIndex:rangeOfLastWantedCharacter.location+1]; // non-inclusive }
