Documentation
stringTrim :: String -> String Source
remove leading and trailing whitespace with standard Haskell predicate isSpace
stringToLower :: String -> String Source
convert string to lowercase with standard Haskell toLower function
stringToUpper :: String -> String Source
convert string to uppercase with standard Haskell toUpper function
stringAll :: Eq a => [a] -> [a] -> [Int] Source
find all positions where a string occurs within another string
stringFirst :: Eq a => [a] -> [a] -> Maybe Int Source
find the position of the first occurence of a string
stringLast :: Eq a => [a] -> [a] -> Maybe Int Source
find the position of the last occurence of a string
normalizeNumber :: String -> String Source
Removes leading / trailing whitespaces and leading zeros
normalizeWhitespace :: String -> String Source
Reduce whitespace sequences to a single whitespace
normalizeBlanks :: String -> String Source
replace all whitespace chars by blanks
escapeURI :: String -> String Source
Escape all disallowed characters in URI references (see http://www.w3.org/TR/xlink/#link-locators)
textEscapeXml :: String -> String Source
escape XML chars < and ampercent by transforming them into character references, used for escaping text nodes
see also : attrEscapeXml
stringEscapeXml :: String -> String Source
escape XML chars <, >, ", and ampercent by transforming them into character references
see also : attrEscapeXml
attrEscapeXml :: String -> String Source
escape XML chars in attribute values, same as stringEscapeXml, but none blank whitespace is also escaped
see also : stringEscapeXml
stringToInt :: Int -> String -> Int Source
stringToHexString :: String -> String Source
convert a string into a hexadecimal string applying charToHexString
see also : charToHexString
charToHexString :: Char -> String Source
convert a char (byte) into a 2-digit hexadecimal string
see also : stringToHexString, intToHexString
intToHexString :: Int -> String Source
convert a none negative Int into a hexadecimal string
see also : charToHexString
hexStringToInt :: String -> Int Source
convert a string of hexadecimal digits into an Int
decimalStringToInt :: String -> Int Source
convert a string of digits into an Int
doubles :: Eq a => [a] -> [a] Source
take all elements of a list which occur more than once. The result does not contain doubles. (doubles . doubles == doubles)
partitionEither :: [Either a b] -> ([a], [b]) Source
