myzol 123gbhj {
    test
    check      myself/mrzulf/.com
}

myzol 123gbhj {
    test
    check      myself/mrzulf/.com
}

myzol 1fde3gbhj {
    test
    check      myself/check/.com
}

myzol 12ecehj {
    test
    check      myself/mrzulf/.com
}

myzol 1evehj {
    test
    check      myself/check/.com
}

Here I have to remove the block which contains mrzulf
I have to replace it with blank.

>Solution :

There is no - in the example strings, and not all the examples end on a digit before the curly like in this part of the pattern [0-9]+\s\{

You can match:

\bmyzol+\s+[^{]*{[^{}]*\bmrzulf\b[^{}]*}

And replace with an empty string.
