removing-whitespace

How do you trim whitespace from the start and end of a string? trim " abc " => "abc" Edit: Ok, let me be a little clearer. I did not understand that string literals were treated so differently from Strings. I would like to do this: import qualified Data.Text as T let s :: String = " abc " in T.strip s Is this possible in Haskell? I am using -XOverloadedStrings but that appears only to work for literals. If you have serious text processing needs then use the text package from hackage: > :set -XOverloadedStrings > import Data.Text > strip " abc " "abc" If you're too stubborn to use text and don

Basically I want to remove all whitespaces and tokenize the whole string as a single token. (I will use nGram on top of that later on.) This is my index settings: "settings": { "index": { "analysis": { "filter": { "whitespace_remove": { "type": "pattern_replace", "pattern": " ", "replacement": "" } }, "analyzer": { "meliuz_analyzer": { "filter": [ "lowercase", "whitespace_remove" ], "type": "custom", "tokenizer": "standard" } } } } Instead of "pattern": " " , I tried "pattern": "\\u0020" and \\s , too. But when I analyze the text "beleza na web", it still creates three separate tokens: "beleza

The function normalize-space removes leading and trailing whitespace and replaces sequences of whitespace characters by a single space. How can I only replaces sequences of whitespace characters by a single space in XSLT 1.0? For instance "..x.y...\n\t..z." (spaces replaced by a dot for readability) should become ".x.y.z." . Without Becker's method, you could use some discouraged character as mark: translate(normalize-space(concat('',.,'')),'','') Note : Three function calls... Or with any character but repeating some expression: substring( normalize-space(concat('.',.,'.')),

I was trying to find a way in powershell to remove more than one white space. But what i found is how to do it in php. " Removing more than one white-space " There will be similar regular expression may available . How to acheive the same in powershell? My string is like this Xcopy Source Desination Some lines may contain more than one white space between Source and destination. If you're looking to collapse multiple consecutive whitespace characters into a single space then you can do this using the -replace operator: '[ Hello, World! ]' -replace '\s+', ' ' ...returns... [ Hello, World! ] The

This question already has an answer here: Remove spaces from std::string in C++ 13 answers In C++, what's an easy way to turn: This std::string \t\tHELLO WORLD\r\nHELLO\t\nWORLD \t Into: HELLOWORLDHELLOWORLD Simple combination of std::remove_if and std::string::erase . Not totally safe version s.erase( std::remove_if( s.begin(), s.end(), ::isspace ), s.end() ); For safer version replace ::isspace with std::bind( std::isspace<char>, _1, std::locale::classic() ) (Include all relevant headers) For a version that works with alternative character types replace <char> with <ElementType> or whatever
