str-replace

I have a string which contains multiple unicode characters. I want to identify all these unicode characters, ex: \ uF06C , and replace it with a back slash and four hexa digits without "u" in it. Example : Source String: "add \uF06Cd1 Clause" Result String: "add \F06Cd1 Clause" How can achieve this in Java? Edit: Question in link Java Regex - How to replace a pattern or how to is different from this as my question deals with unicode character. Though it has multiple literals, it is considered as one single character by jvm and hence regex won't work. Paul The correct way to do this is using a

I've researched and need to find the best way to replace a need with an array of possibilities randomly. ie: $text = "Welcome to [city]. I want [city] to be a random version each time. [city] should not be the same [city] each time."; $keyword = "[city]"; $values = array("Orlando", "Dallas", "Atlanta", "Detroit", "Tampa", "Miami"); $result = str_replace("[$keyword]", $values, $text); The result is every occurrence has "Array" for city. I need to replace all of the city occurrences with a random from $values. I want to do this the cleanest way possible. My solution so far is terrible (recursive

This is the string i'm trying to replace white spaces between the words with "-". $mystring = "Color red, Color blue, Color black"; $newstring = str_replace(' ', '-', $mystring); What i want to achieve, using the str_replace function, is: "Color-red, Color-blue, Color-black"; But that returns: "Color-red,-Color-blue,-Color-black"; I guess i need a condition that replaces white spaces "not after the comma" or "between two words". But i have no idea. Any suggestion? (?<!,)\s That uses a negative lookbehind to match all spaces ( \s ) that aren't followed by a , . preg_replace("/(?<!,)\s/", '-',

I would like to do a string replacement in all items in an array. What I have is: $row['c1'] = str_replace("&", "&", $row['c1']); $row['c2'] = str_replace("&", "&", $row['c2']); $row['c3'] = str_replace("&", "&", $row['c3']); $row['c4'] = str_replace("&", "&", $row['c4']); $row['c5'] = str_replace("&", "&", $row['c5']); $row['c6'] = str_replace("&", "&", $row['c6']); $row['c7'] = str_replace("&", "&", $row['c7']); $row['c8'] = str_replace("&", "&", $row['c8']); $row['c9'] = str_replace("&", "&", $row['c9']); $row['c10'] = str_replace("&", "&", $row['c10']); How can I achieve this with less

Given the following string, "Hi ~+ and ^*. Is ^* still flying around ~+?" I want to replace all occurrences of "~+" and "^*" with "Bobby" and "Danny", so the string becomes: "Hi Bobby and Danny. Is Danny still flying around Bobby?" I would prefer not to have to call Boost replace function twice to replace the occurrences of the two different values. I managed to implement the required replacement function using Boost.Iostreams. Specifically, the method I used was a filtering stream using regular expression to match what to replace. I am not sure about the performance on gigabyte sized files.
