[issue] Help needed to extract value using extractors

[allwin101]

Describe the bug
I have tried extracting the value from using extractors. It is working well in regex builder but not in yaml file. Not sure what I am missing. Help needed to build regex for the above input tag to extract only the value.

Nuclei version
Nuclei 2.1

Screenshot of the error or bug
It would be helpful to have generic regex examples like above as part of documentation while building templates for easy correlation
