Getting items from the string list
 
Greetings,

I'm wondering if there is a possibility to get all occurrences (in case where there are more than one in string list) of an item from the string list returning it's number in the list (something like %ismember but to return more items)?

Eg.

$string = a|b|c|d|a|e|f|a|a

%ismember(a,$string) will return only one item (1 to be exact) ignoring rest (so 5, 8 and 9). Anyone know how to return all of them? Thanks in advance.

Regards,
V.

#LOCAL $place $list
#FORALL $string {$place=($place+1);#IF (%i=a) {#ADDITEM $list %i}}
#SAY $list

This unfortunately does not work (still returns only first occurrence).

I think I explained my issue incorrectly.

I've got string list @allM with names of known players, @alloM with short description of those (in the same order so eg. fifth item in @allM is correlated to fifth item in @alloM). As none of those are unique duplicates can be found in both of those string lists. What I need:

Example:

@allM = John|Steve|Paul|Roderick
@alloM = short fat dwarf|big stubborn elf|short fat dwarf|little big man

Pattern:
Short fat dwarf.

What I want to see:
Short fat dwarf (John, Paul).

Hope it's clearer now.

PS. Got it working - just needed to replace last %i with %item(@list,$place).

Sorry bout that, i had just woken up.
#FORALL $string {$place=($place+1);#IF (%i=a) {#ADDITEM $list $place}}

was how i meant it to be, then $list contains all the %item numbers it occurs at

but if you got it working for you, great

Vaxon why not just create a data record instead of parallel lists (arrays)?

Example:

Code:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
  <var name="allMembers" type="Record" copy="yes">
    <value>John=short fat dwarf|Steve=big stubborn elf|Paul=short fat dwarf|Roderick=little big man</value>
    <json>{"Roderick":"little big man","Paul":"short fat dwarf","John":"short fat dwarf","Steve":"big stubborn elf"}</json>
  </var>
  <alias name="FindDesc" copy="yes">
    <value>#local $list
$value = %trim(%params)
#loopdb @allMembers
{
  #if ($value == %val)
  {
    #additem $list %key
  }
}
#print {$value [%expandlist($list,", ")]}</value>
  </alias>
</cmud>


Entering "FindDesc short fat dwarf" returns the following:

short fat dwarf [John, Paul]
