Replace nth occurence in a string between two characters

i have to use regular expressions to cross out some content in a string.

For example
SomeText;content1|content2|content3|||content6||content8

As you can see, the contents are separated by pipes. Contents do not have a fixed length and can consist of any characters. Now I want to replace content6 by xxxxxx. Therefore I need something like "replace the content between the pipes on occurence number 6"

Result should be: SomeText;content1|content2|content3|||xxxxxx||content8

Does anyone have an idea how to do this? Thank you in advance!

Assuming that there won't be any "escaped pipes" we need to deal with, you could search for

^((?:[^|]*\|){5})[^|]*(.*)$

and replace that with \1xxxxxx\2.

Test it live on regex101.com.

Explanation:

[^|]* matches any number of characters besides |, so (?:[^|]*\|){5} matches everything up to and including the 5th pipe.
