may help you . Please have a look at your ( ?([0-9]+)-?)+ regex demo: only 4 6 8 2 5-3 4 3 9 line is matched as a whole line while 4 -6 8 2 5-3 4 3 9, -4 6 8 2 5 -3 4 3 9, and 4 -6 8 2 5-3 4 3 9 are matched partially.
If you get false, it means you are using .matches() method. You may use
code :
(?: ?-?([0-9]+))+

Any of those help INPUT , I would recommend using Matcher.appendReplacement:
code :
public static void main(final String[] args) throws Exception {
    final String[] loginURLs = {
        "http://ip:port/path?username=abcd&location={LOCATION}&TXT{UE-IP,UE-Username,UE-Password}&password={PASS}",
        "http://ip:port/path?username=abcd&location={LOCATION}&password={PASS}&TXT{UE-IP,UE-Username,UE-Password}",
        "http://ip:port/path?TXT{UE-IP,UE-Username,UE-Password}&username=abcd&location={LOCATION}&password={PASS}",
        "http://ip:port/path?TXT{UE-IP,UE-Username,UE-Password}",
        "http://ip:port/path?username=abcd&password={PASS}"};
    final Pattern patt = Pattern.compile("(\\?)?&?(TXT\\{[^}]++})(&)?");
    for (final String loginURL : loginURLs) {
        System.out.printf("%1$-10s %2$s%n", "Processing", loginURL);
        final StringBuffer sb = new StringBuffer();
        final Matcher matcher = patt.matcher(loginURL);
        while (matcher.find()) {
            final String found = matcher.group(2);
            System.out.printf("%1$-10s %2$s%n", "Found", found);
            if (matcher.group(1) != null && matcher.group(3) != null) {
                matcher.appendReplacement(sb, "$1");                
            } else {
                matcher.appendReplacement(sb, "$3");
            }
        }
        matcher.appendTail(sb);
        System.out.printf("%1$-10s %2$s%n%n", "Processed", sb.toString());
    }
}

Java regex matcher doesnt match


By : Ryan Rodrigues
Date : March 29 2020, 07:55 AM
wish help you to fix your issue The escaping character in both regex and java String literals is a backslash, not a forward slash. You want to get \d in regex (escaped d for digits). You have to escape it by another backslash in string literal, so you obtain \\d.
With
code :
"place (\\d+);(\\d+);(\\d+);(\\d+)"
String pattern = "place (//d+);(//d+);(//d+);(//d+)".replaceAll("//", "\\\\");

Java regex doesnt match outside of ascii range, behaves different than python regex

hop of those help? As suggested by Wiktor in the comments, you could use (?U) to turn on the flag UNICODE_CHARACTER_CLASS. While this does allow matching äöa, this still doesn't match m². That's because UNICODE_CHARACTER_CLASS with \w doesn't recognize ² as a valid alphanumeric character. As a replacement for \w, you can use [\pN\pL_]. This matches Unicode numbers \pN and Unicode letters \pL (plus _). The \pN Unicode character class includes the \pNo character class, which includes the Latin 1 Supplement - Latin-1 punctuation and symbols character class (it includes ²³¹). Alternatively, you could just add the \pNo Unicode character class to a character class with \w. This means the following regular expressions correctly match your strings:
code :
[\pN\pL_]{2,}         # Matches any Unicode number or letter, and underscore
(?U)[\w\pNo]{2,}      # Uses UNICODE_CHARACTER_CLASS so that \w matches Unicode.
                      # Adds \pNo to additionally match ²³¹
int _PyUnicode_IsDecimalDigit(Py_UCS4 ch)
{
    if (_PyUnicode_ToDecimalDigit(ch) < 0)
        return 0;
    return 1;
}
int _PyUnicode_ToDecimalDigit(Py_UCS4 ch)
{
    const _PyUnicode_TypeRecord *ctype = gettyperecord(ch);

    return (ctype->flags & DECIMAL_MASK) ? ctype->decimal : -1;
}

Dynamic input text box id doesnt match the regex format. shows undefined

To fix this issue You may want to use a better selector for the input elements. You can use input[id^='points'] for example. This will look for input elements with a the id that starts with points.
Consider the following example:
code :
var results = $("input[id^='points']");
var points = 'Enter a valid point.';
var regex = '/^[A-Za-z!@#></!?\$%\^\&*\)\(+=._-]+$/g';
results.each(function(i, el) {
  if ($(el).val().match(regex)) {
    console.log("Match on #" + $(el).attr("id"));
    $(el).next('span').html('');
    $("<span>", {
      class: "errTextboxClass"
    }).css("color", "#e03b3b;").html(points).insertAfter($(el));
    $(el).focus();
  }
});
^[\D]+$
$(function() {
  $("input[id^='points']").keypress(function(e) {
    console.log(e.which);
    if (e.which !== 46 && (e.which < 48 || e.which > 57)) {
      e.preventDefault();
    }
  });
});
label {
  width: 80px;
  display: inline-block;
}
