GetToken 643
<cfoutput>
#mystring#<br><br>
</cfoutput>
The output is as follows:
four,
,five, nine,zero:;
nine,ten:, eleven:;twelve:;thirteen,
,four
The
GetToken
function recognizes explicit spaces, tabs, or newline characters as the parameter
delimiters (To specify a space character, the code is
chr(32)
; a tab character,
chr(9)
; and a
newline character,
chr(10)
.
)
In the example string
mystring
, there is:
•
A forced space between the substrings "
four,"
and
",five"
•
A literal space between "
five,"
and "
nine"
•
A literal space between "
ten:,"
and "
eleven,"
•
A forced space between "
thirteen,"
and "
,four"
In the following call against
mystring
, no spaces are specified in
delimiters
(it is omitted), so
the function uses the space character as the
string
delimiter:
<br>
<cfoutput>
GetToken(mystring, 3) is : #GetToken(mystring, 3)#
</cfoutput><br>
The output of this code is as follows:
GetToken(mystring, 3) is : nine,zero:;
The function finds the third delimiter, and returns the substring just before it that is between the
second and third delimiter. This substring is "
nine,zero:;".
Example C : Consider the following code:
<cfset mystring2 = "four,"
&#chr(9)# & #chr(10)#
& ",five,nine,zero:;"
& #chr(10)#
& "nine,ten:,eleven:;twelve:;thirteen,"
& #chr(9)# & #chr(10)# & ",four">
<cfoutput>
#mystring2#<br>
</cfoutput>
The output is as follows:
four,
,five,nine,zero:;
nine,ten:,eleven:;twelve:;thirteen,
,four
