Is it possible to convert querySelectorAll to RegExp?

Question

Parsing

In many html parsers, and in js itself, you can get dom elements using the querySelectorAll function.
I'm going to parse a table from several sites. Through querySelectorAll, a simple string for parsing is obtained: tr[id^='vbpostrow_'] td:nth-child(4
) performance is higher.
Hence the question itself, is it possible to convert querySelectorAll to RegExp?
