How to get a value out a list?

Hi all,

If i have a notecard with 4 values a line and several lines and place them with a notecard reader in a list. What is then the best way to get 4 values in 4 different variables everytime i go to a new line in the list? To place lines from a notecard in a list i know but i can't find how to get a value out a list if there are more values at 1 line.

Example in pseudo code
/notcard
string1, string2, string3, integer4
stringA, stringB, stringC, integerD
several more lines
/end notecard

/Script
notecard reader read all in list Products

movefirst
variable1=products.line1.value1(string1)
variable2=products.line1.value2(string2)
variable3=products.line1.value3(string3)
variable4=products.line1.value4(integer4)

after a movenext
variable1=products.line2.value1(stringA)
variable2=products.line2.value2(stringB)
variable3=products.line2.value3(stringC)
variable4=products.line2.value4(integerD)
/End script


Or is it better that the notecard reader splits the 4 values in 4 different lists?

Thanks

LlParseString2List http://wiki.secondlife.com/wiki/LlParseString2List.

thanks for your answer.

Do you mean to break the notecard lines in 4 entries in the list?

this will create (i think):
list Product =[ "string1", "string2", "string3", "integer4", "stringA", "stringB", "stringC"," integerD"]

or use LlParseString2List on each line of the orginal list products and create a new 'sub'
list with only 4 values?

Think both would work but which is the best? (less lag)

I think you might be looking for llList2String

if i understand it well it will be something like this?

list Products;
integer LineNr

list Items = llParseString2List(llList2String(Products, LineNR))

string variable1 = llList2String(Items, 0)
string variable2 = llList2String(Items, 1)
string variable3 = llList2String(Items, 1)
string variable4 = llList2String(Items, 3)

Think i start endly understand a little of lists

If it were me, I'd probably do it in one list.

So then if you wanted to refer to them you might do...

variable1 = llList2String(nIndex, products);
variable2 = llList2String(nIndex+1, products);
variable3 = llList2String(nIndex+2, products);
variable4 = llList2Integer(nIndex+3, products);

-edit- I may have put those parameters in backwards, lol

if i do it in 1 list i get to much information
the orginal products list has 4 items a line

i only want 1 of the 4 items

variable1 = llList2String(products, nIndex) gives "string1, string2, string3, integer4"

or do is see something wrong?

Try llCSV2List, it works with commas, but you'll want to be careful of what string-data you have in your notecard.

So your dataserver event might looking something like:

dataserver(key id, string data) {
    list parts = llCSV2List((data = "") + data);
    string variable1 = llList2String(parts, 0);
    string variable2 = llList2String(parts, 1);
    string variable3 = llList2String(parts, 2);
    integer variable4 = llList2Integer(parts, 3);
}

Obviously you can trim out some of those lines to get the values you want.
