First for all, I'm not good with these
Secondly I looked some threads from scripting section about regex, but I didn't quite understand.
Third, sry for bad english
Fourth, lousy tutorial

My snippet

PHP Code:

Plah()
{
    new String:regex_expression_pattern[] = { "^M\\w+" };    // Pattern same as = /^M\w+/g
    new Handle:regex = CompileRegex(regex_expression_pattern, PCRE_MULTILINE); // Including multiline flag = /^M\w+/gm

    if(regex == INVALID_HANDLE)
    {
        return;
    }

    new String:input_text[] = { "Example input text\nMary this\nMary that\nlamb died\nmary cry" };
    new skip_text;

    new substrings;
    new String:buffer[sizeof(input_text)];

    while( (substrings = MatchRegex(regex, input_text[skip_text])) > 0 ) // When the first string of input text match with expression pattern.
    {
        // Pick whole string matching with expression pattern.
        if( !GetRegexSubString(regex, 0, buffer, sizeof(buffer)) )
        {
            break;
        }
        PrintToServer("%s", buffer);

        // We do not want regex to hit the same part of the input text. Skip the first piece of input text in the next cycle.
        skip_text += StrContains(input_text[skip_text], buffer);
        skip_text += strlen(buffer);

        // If regex expression pattern include capturing parentheses = /(x)(x)/
        // The matching strings are stored in array, variable substrings contains the number of strings
        for(new index = 1; index < substrings; index++)
        {
            if( !GetRegexSubString(regex, index, buffer, sizeof(buffer)) )
            {
                break;
            }
            PrintToServer("%s", buffer);
        }

    }

    CloseHandle(regex);
} 


How this work

- When expression pattern find first match from input text,
for example now it will find the first line of the letter M and picks up the rest of the letters.

Example input text
Mary this
Mary that
lamb died
mary cry

- Then search again a position in the input text where the match starts StrContains
- + Counts how long matching string is strlen
- In next loop cycle, it skip the first piece of input text.

Example input text
Mary this
Mary that
lamb died
mary cry

- And continue same way, find a match.

Example input text
Mary this
Mary that
lamb died
mary cry

- Skip first part.

Example input text
Mary this
Mary that
lamb died
mary cry

- Then will end because it not find anymore matching part inside input text.
So result was

Mary
Mary

If we use capturing parentheses in regex pattern (x), we get more substrings.

PHP Code:

new String:regex_expression_pattern[] = { "(\\w+) (\\w+)" }; // Same as = /(\w+) (\w+)/ 


Regex store matching string parts in array.
For quick example now it will pick two words what have space between of them.

Example input text
Mary this
Mary that
lamb died
mary cry

Result will be this

Example input
Example
input
Mary this
Mary
this
Mary that
Mary
that
lamb died
lamb
died
mary cry
mary
cry

Zipped test plugin

server cmd

test

Plugin read two files:

• addons \sourcemod\configs\regex_example\pattern.txt
• addons \sourcemod\configs\regex_example\sample.txt

Add input text inside sample.txt file.
Add expression pattern in first line inside pattern.txt file.
Type in server console input cmd test and see result from server console.

And yes, server console have limits to show text and will show non-ASCII based characters wrong. (Ä Ö Å ö ä å, etc. etc.)

I'll share some of mine:
Valid integer (useful for StringToInt implementation):

"[+-]?\\b\\d+\\b"

Valid float (useful for StringToFloat implementation):

"[+-]?(\\b\\d+(\\.\\d+)?|(\\b\\d+)?\\.\\d+)([eE][+-]?\\d+)?\\b"

Tokenizing semicolon delimited string:

"([^;\"]+|\"[^\"]*\")+"

Tokenizing arguments of console command call:

"[\\S\"]+|\"[^\"]*\""

C++ style comment:

"//.*$"
