Error location should be easy to find / counting CFI

[typopaul]

Is there an easy way to find a location that is given with the CFI?
Currently I am desperatly looking for the cause of the error/warning below. But the message does not help much.
I know in which file the error is in. But after that it is counting elements and trying to find the right location.

So my general question is:
Can the error messages include a line or a text snippet that is actually helping to find the error without interpreting the CFI?

 "Teil B"

text/008_400699_003.xhtml#epubcfi(/4/2/6/10)

Snippet (I added some line breaks to make the non-helpful information easier to see):
