So basically you to first split by – and then each side by a non-word character. Therefore you can try: String s = “ABC_DEF-HIJ (KL MNOP_QRS)”; String[] splits = s.split(“-“); // {“ABC_DEF”, “HIJ (KL MNOP_QRS)”} String[] lefts = split[0].split(“[^a-zA-Z]”); // {“ABC”, “DEF”} String[] rights = split[1].split(“[^a-zA-Z]”); // {“HIJ”, “”, “KL”, “MNOP”, “QRS”} String string1 = … Read more
To get the part of the string after the first space: string city = str.Substring(str.IndexOf(‘ ‘) + 1); This will also give a result even if there happens to be no space in the string. The IndexOf method will return -1 in that case, so the code will return the entire string. If you would … Read more
Hi @HZan hope you doing well, I’m not that good at java but you can use kotlin snippet equivalent in java to get the desired result if the fold function isn’t available, you could use forEach or any other accumulator pattern to achieve the same, val phNum = “01 12 1234 123 – 124 – … Read more
On my Debian/Sid/x86-64 the below program (in source file itsols.cc compiled with the command g++ -Wall itsols.cc -o itsols) #include <iostream> #include <string> int main(int, char**) { std::string s = “Hello”; std::cout << s[3] << std::endl; return 0; } displays a single lower-case l (compiled with g++ -Wall itsols.cc -o itsols, both with GCC 4.7.2 … Read more
You’re going to have to provide more than just this snippet of code. What is the Time object you’re accessing via an indexer? Have you debugged this to see if Time[0] actually has a value? My guess here would be that Time[0] doesn’t return a value that DayOfWeek can work with hence Substring(0,3) is being … Read more
It’s very unclear what you want to do because on the one hand you mention you want to use Substring and IndexOf, and on the other hand, you put it on comment and say you want to check if it’s null, and which you’re already checking if the string customFolders is null or empty. I … Read more
I’m not sure if this matches what you need but you could try: var myString = “!re=.id=2CB=name=xxname123=service=vpn=caller-id=”; var match = new Regex(@”\.id=(?<value>[^=]*)=”).Match(myString); var id = match.Groups[“value”].Value; I haven’t tested this for specific syntax, but that should get you just that captured string. You can modify that to iterate across a MatchCollection if you need to … Read more
Basically: take the pattern (containing 3 groups), replace instr with second group from pattern. private string MyReplace(string inStr, string leaveStr) { string pattern = @”(.*?)(” + leaveStr + “)(.*)”; string repl = @”*$2*”; Regex rgx = new Regex(pattern); return rgx.Replace(inStr, repl); } string x = MyReplace(@”\textbf\{atext\}”, “atext”); x = MyReplace(@”\textbf\{1\}”, “1”); full string – group … Read more
It means that the values you are passing to Substring are not valid for the string they are being called on. For example: string s = “hello”; string x = s.Substring(0, 1); // <– This is fine (returns “h”) string y = s.Substring(1, 3); // <– Also fine (returns “ell”) string z = s.Substring(5, 3); … Read more
Here is a program with comments explaining how you can do what you want. Hopefully it will help you learn how to solve such problems. #include <stdio.h> #include <stdlib.h> #include <string.h> /* Use if strdup() is unavailable. Caller must free the memory returned. */ char *dup_str(const char *s) { size_t n = strlen(s) + 1; … Read more
As mentioned you can’t call substr() with a std::ifstream. What you probably meant was to take the parts from the line string read in a[i]= stoi(line.substr(4,2)); name[i]= line.substr(18,15); b[i]= stoi(line.substr(36,1)); Also note you’ll need to convert the substrings extracted to a number (instead of assigning them directly), hence I have added the stoi(). As also … Read more
>>> import re >>> words = [“hello”, “18hs”, “18aaa”, “21hr”] >>> [w for w in words if not re.match(r’\d+h’, w)] [‘hello’, ’18aaa’] This loops over the list and keeps the items that don’t match the regex \d+h, which means “one or more digits followed by an h”. If you need to keep strings like 7hg, … Read more
First get the email address to parse. You’ve already done that. Here, x contains the email address. var x = document.getElementById(“myText”).value; Now you can use x.indexOf(“.”) to get the position of the first period. Likewise, use x.indexOf(“@”) to get the position of the “@” symbol. These two values are passed to x.substring() to get the … Read more
A crude but working example. you can further improve upon it. Call GetEverythingFromThird(“https://stackoverflow.com/questions/ask”, “https://stackoverflow.com/”); The method: static string GetEverythingFromThird(string instring, string checkitem) { string outstring = “”; //1st occurence int index = instring.IndexOf(checkitem); outstring = instring.Substring(index + 1); //2nd occurence index = outstring.IndexOf(checkitem); outstring = outstring.Substring(index + 1); //3rd occurence index = outstring.IndexOf(checkitem); outstring = … Read more
Use substr. The first value is the string, the second is the starting character position (in your case, 2 is in position 0, the – is in position 1, etc.). You can also specify a length as a third parameter if you so choose. $s = substr($str, 2); solved PHP: get every character of a … Read more
