RegExp Parser for Tag-Like String


RegExp Parser for Tag-Like String

this one helps. Regex can't deal with nested expressions (unless you have access to a powerful implementation of regex, which javascript doesn't), so a pure-regex solution is out of the question. But there's still an easy way to do this:
replace all occurences of \{(\w+)\}((?:(?!\{\w+\}).)*)\{\/\1\} (this matches a {tag}...{/tag} pair, but only if it does not contain another {tag} ) with 00b4f[ $2 00b4d] . repeat until there are no more matches.
code :
var tagPattern = /\{(\w+)\}((?:(?!\{\w+\}).)*)\{\/\1\}/g,
    tagReplacer = function ($0, $1, $2) {
        switch ($1) {
            case "b": return "00b3f[" + $2 + " 00b3d]";
            case "red": return "00b4f[" + $2 + " 00b4d]";
            default: return $2;
        }
    };

while (tagPattern.test(sourceString)) {
    sourceString = sourceString.replace(tagPattern, tagReplacer);
}

Is it possible to simulate string.match with a regexp.exec loop when the regexp matches the empty string?

Hope that helps One (icky) solution is to make sure it's not in the same place as last time:
code :
var s = '1234'
var r = /()/g;
var m;
var i = 0;
var lastPosition = -1;

while(m = r.exec(s)) {
    if(m.index === lastPosition) {
        r.lastIndex++;
        continue;
    }

    lastPosition = m.index;

    console.log(i, m[0]);
}

it helps some times Not sure what test code is there, or how is the shell script related, but item value parsing in Zabbix is not supported yet, it is coming for Zabbix 3.4: https://support.zabbix.com/browse/ZBXNEXT-1443 .

How do I use a JS regexp to match a string only if the regexp matches the entire string(no substring)

How do I use a JS regexp to match a string only if the regexp matches the entire string(no substring)

wish helps you I am on this FCC challenge. In this challenge, you are asked to create a regexp to match a string only if it has the same number repeated 3 times with spaces in between. This means that a string with 4 numbers with spaces in between would not count as a valid match even though the regexp below would match it. How could I modify my regexp to match a string ONLY IF it has a specific number repeated 3 times, no more, no less. , You can use ^ and $ to match the beginning and end of the string:
code :
const re = /^(\d+) \1 \1$/;
console.log(re.test("42 42 42"));
console.log(re.test("42 42 42 42"));
console.log(re.test("42 42"));
