nasl question : split and arrays

Hello,

I have a string that looks like this

mystring="value1=1 value2=a value3=cd value4=jj";

I would like to be able to put this in individual arrays (each of 2 elements) that can be walked through via a "foreach" iteration

My first idea was to use 2 split functions

array1=split(mystring," ");
then for each array1 member, split it again :
foreach arraymember (array1)
{
arrayentry=split(arraymember,"=");
foreach field (arrayentry)
{
display(string("item :",field,"\n");
}
}

but this does not seem to work... I get the entire string every time, so it looks like the split function is not doing anything
(however, when I do a split without parameters on a large chunck of text, trying to split this text into lines, it works fine.. but as soon as I want to use a separator, it stops working)

what is wrong here ?

thanks

The separator is a named argument: sep: " ".
And You probably want to remove it: "keep: 0"

This works:

mystring="value1=1 value2=a value3=cd value4=jj";
array1=split(mystring, sep: " ", keep: 0);
foreach arraymember (array1)
{
arrayentry=split(arraymember, sep: "=", keep: 0);
foreach field (arrayentry)
{
display("item :",field,"\n");
}
}

Re: nasl question : split and arrays [In reply to]

Great, thanks !

I have published my plugin on my blog...
It basically is a wrapper/output parser for ike-scan,
more info can be found at

http://www.corelan.be:8800/index.php/2009/01/31/nessus-wrapper-for-ike-scan/

(it still may be a bit buggy, it most likely can be improved and extended, the code probably needs some cleaning up... but hey, this is my first script, so this is a learning process for me...)

Any comments/feedback/... is more than welcome
