I think the issue was by ths following , If I have some string newStr = 1×1 cell array , You can do this with str2num
a = {'1 25 27 45 46 62 65 70 73 76 77:83'}
my_array = str2num(a{1})

my_array =

  Columns 1 through 12

     1    25    27    45    46    62    65    70    73    76    77    78

  Columns 13 through 17

    79    80    81    82    83

this will help Hello i had a problem on separating a string. Below are the sample string. , You can do:
var input = "D93:E93 E98 E9:E10 E26 D76:E76 D83:E83 D121:D124";
var list = input.Split(' ');

var result = new List<String>();
foreach (var item in list)
{
    var parts = item.Split(':');
    if (parts.Length == 1) result.Add(parts[0]);
    else
    {
        if (parts[0].Substring(0, 1).CompareTo(parts[1].Substring(0, 1)) == 0)
        {
            var i = Convert.ToInt32(parts[0].Substring(1));
            var j = Convert.ToInt32(parts[1].Substring(1));

            while (i < j)
            {
                result.Add(parts[0].Substring(0, 1) + i);
                i++;
            }

            if (i == j)
            {
                result.Add(parts[0].Substring(0, 1) + i);
            }
        }
        else
        {
            result.Add(parts[0]);
            result.Add(parts[1]);
        }
    }
}
Console.WriteLine(string.Join(", ", result));

//output
D93, E93, E98, E9, E10, E26, D76, E76, D83, E83, D121, D122, D123, D124

will be helpful for those in need How can I split this string power:110V;220V;Color:Pink;White;Type:1;2;Condition:New;Used; into these 4 strings , Split your input according to the below regex.
string.split("(?<=;)(?=\\w+:)");
string.split("(?<=;)(?=[^;:]*:)");
String s = "power:110V;220V;Color:Pink;White;Type:1;2;Condition:New;Used;";
String[] parts = s.split("(?<=;)(?=\\w+:)");
for(String i: parts)
{
    System.out.println(i);
}

How to read a text file and search for a certain string before a colon and then show the content after the colon?


Tag : php , By : user142345

seems to work fine This should work for you:
Just get your file into an array with file() and then simply preg_grep() all lines, which have the search string before the colon.
<?php

    $file = "file.txt";
    $search = "test";

    $lines = file($file, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);

    $matches = preg_grep("/^" . preg_quote($search, "/") . ":(.*?)$/", $lines);
    $matches = array_map(function($v){
        return explode(":", $v)[1];
    }, $matches);

    print_r($matches);

?>
Array ( [0] => fOwimWPu0eSaNR8 )

MATLAB error: Input arguments to function include colon operator. To input the colon character, use ':' instead


Tag : matlab , By : Vorinowsky

wish helps you When using subsref you can not use the colon operator, you have to pass the string ':' and it will be evaluated to the colon operator by subsref:
Y = subsref(eye(num_labels),struct('type','()','subs',{{y,':'}}));
Y = eye(num_labels)
Y = Y(y,:)
Y=[1:num_labels==y]

Is there a difference between the COLON unicode and a colon in a string for regex expressions?
