how can i delete all lines except those beginning with a determined string. By example : Delete all lines except those beginning with "5234534".

Use search functionality
Search for line containing your string, check Non matched lines and press COPY buttton
Into new file will be copied content what doesn't match

If you want lines, starting for some exact expression, use regular expression
Search for: ^5234534.*
[x]Regular expression
[x]Copy nonmatching + COPY button

You can use another way - empty lines you don't want with search/replace:
Search: ^5234534.*
Replace: (empty)
[x]Regular expressions
Followed by function to remove empty lines from menu Edit / Line manipulation
