delimiter

问题 I'm looking to parse the following string in java <some lines here> Key1:thingIWantToKnow Key2:otherThing Key3:bla Key4:bla Key5:bla <(possibly) more lines here> All lines end with a newline (\n) character. I'm looking to store the value pair once I find the key's I'm care about. 回答1: If a Map is what you want: Map<String, String> keyValueMap = new HashMap<String,String>(); String[] lines = input.split("\n"); if (lines == null) { //Compensate for strange JDK semantics lines = new String[] {

问题 I have an input file something like this: some line some other line another line start_delimiter interesting stuff more interesting stuff even more interesting stuff end_delimiter possibly more stuff I want to manipulate the lines between start_delimiter and end_delimiter that match a regex pattern and write the results to the input file. For example, add '//' to the beginning of the lines containing the word 'more' (as long as those lines are between the delimiters): some line some other

问题 I'm developing a C# web application in VS 2008. I let the user select an input file and then I store the file path in a string variable. However, it stores this path as "C:\\folder\\..." . So my question is how do I convert this file path into single "\"? Thank you guys for all your helps! Please forgive me as I am a newbie to ASP.NET development. This is more of my code in context. First I want to see if the directory exists. I guess I don't have to check this if I check if the file exists.

问题 Is there any Java open source library that supports multi-character (i.e., String with length > 1) separators (delimiters) for CSV? By definition, CSV = Comma-Separated Values data with a single character (',') as the delimiter. However, many other single-character alternatives exist (e.g., tab), making CSV to stand for "Character-Separated Values" data (essentially, DSV: Delimiter-Separated Values data). Main Java open source libraries for CSV (e.g., OpenCSV) support virtually any character

问题 I need to be able to figure out which delimiter is being used in a csv file (comma, space or semicolon) in my Ruby project. I know, there is a Sniffer class in Python in the csv module that can be used to guess a given file's delimiter. Is there anything similar to this in Ruby ? Any kind of help or idea is greatly appreciated. 回答1: Looks like the py implementation just checks a few dialects: excel or excel_tab. So, a simple implementation of something that just checks for "," or "\t" is:

问题 What is the best way to have the functionality of the StreamReader.ReadLine() method, but with custom (String) delimiters? I'd like to do something like: String text; while((text = myStreamReader.ReadUntil("my_delim")) != null) { Console.WriteLine(text); } I attempted to make my own using Peek() and StringBuilder , but it's too inefficient. I'm looking for suggestions or possibly an open-source solution. Thanks. Edit I should have clarified this earlier...I have seen this answer, however, I'd
