Parameters
Parameter | Description |
string | A string or a variable that contains one. String in which to search. |
index | Positive integer or a variable that contains one. The position of a token. |
delimiters | A string or a variable that contains one. A delimited list of delimiters. Elements may consist of multiple characters.Default list of delimiters: space character, tab character, newline character; or their codes: "chr(32)", "chr(9)", chr(10). Default list delimiter: comma character. |
Usage
The following examples show how this function works.
Example 1
In the following example, the function call requests element number 2 from the string, using the delimiter "[:;".
<cfoutput>#GetToken("red,blue:;red,black,tan:;red,pink,brown:;red,three", 2, ":;")#</cfoutput>The output is as follows:
red,black,tan
Example 2
<cfset mystring = "four,"
& #chr(32)# & #chr(9)# & #chr(10)#
& ",five, nine,zero:;"
& #chr(10)#
& "nine,ten:, eleven:;twelve:;thirteen,"
& #chr(32)# & #chr(9)# & #chr(10)#
& ",four">
<cfoutput>
#HTMLCodeFormat(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 ";".
Example 3
<cfset mystring2 = "four," &#chr(9)# & #chr(10)# & ",five,nine,zero:;" & #chr(10)# & "nine,ten:,eleven:;twelve:;thirteen," & #chr(9)# & #chr(10)# & ",four"> <cfoutput> #HTMLCodeFormat(mystring2)#<br> </cfoutput> |
The output is as follows:
four, ,five,nine,zero:; nine,ten:,eleven:;twelve:;thirteen, ,four |
The following is a call against mystring2:
<cfoutput> GetToken(mystring2, 2) is : #GetToken(mystring2, 2)# </cfoutput> |
The output is as follows:
GetToken(mystring2, 2) is : ,five,nine,zero:; |
The function finds the second delimiter, and returns the substring just before it that is between the first and second delimiter. This substring is ",five,nine,zero:;".
