How to correctly formulate an Xpath with "any number of characters between"?

Question

XPath

XPath is copied like this:
//*[@id="TREY_96399541"]/div[2]/span
Tell me how to change 96399541 to any number of characters between _ and " ?
PS 96399541 is a tricky identifier that needs to be bypassed when parsing.

Answer 1

On the other hand, surely not?
For example:
//*[contains(@id, "TREY_")]/div[2]/span
