[Gambas-user] An utility component for Gambas

[Julio Sanchez]

Hi, Benoît:

 I think this function is interesting: Between

Function Between(string_large as string, word_begin as string, word_end as
string) as string

DIM iinf AS Integer
DIM isup AS Integer
iinf = InStr(string_large,word_begin) + Len(word_begin)
isup = InStr(string_large ,  word_end, iinf)
RETURN Mid(string_large , iinf, isup - iinf)

END

The Between function is the one responsible for finding and extracting a
part of a chain , this contained in a larger string between two words (or
strings).
example :

string_large=" Hello Gambas [improvements] 3.6.9 [/improvements] :)"
word1="[improvements]"
word2="[/improvements]"

text = Between(string_large,word1,word2)

print text
" 3.6.9 "


Note:
Ideally extend to extract parts of web pages ( "<div>" and "</div>" , and
supports nested structures "<div>")

text = "<div> Hello <div> bye </div> <div> "

content = between ( text , "<div>", "</div>")

print content
"<div> bye </div> "

Regards

Julio
