hi!
i would like to know if there is any way to select the text between 2 marks.
I know to do it with bookmarks but i think that it is a very bad solution(too
slow)
i´ll put an example because the marks aren't the same at the start and at
the end

if i have this text
P*1.1*Antecedentes*Hasta la fecha actual*
x*a1* este es el anexo primero**17
A*a1* este es el apendice primero
x*a2* este es el anexo primero**15
x*a3* este es el anexo primero**22
A*a1* este es el anexo primero

i want to extract the text that has an 'x' at the beginning of the line,
from the firs asteristic, till the end of the paragraph
for example:
a1*este es el anexo primero**17
