I have tried the below solution its working as expected.

//*[string-length(normalize-space(text())) > 0]

text() Selects all strings

normalize-space(text()) Selects all strings removing their spaces

string-length(normalize-space(text())) > 0 Selects all texts not empty strings

//*[CONDICTION] searching in all document based in a condiction
