skip step in foreach

Hi, any help, please?

Here is the code

| makeresults
| eval tmp_1=1
| eval tmp_2=""
| eval tmp_3=3
| eval tmp=""
| foreach tmp_*
[| eval tmp = tmp ."|".if(isnotnull(<<FIELD>>),<<FIELD>>,"")]
| eval tmp=substr(tmp, 2)
| table tmp

Output is: tmp=1||3

I would like to have output tmp="1|3", it means how to skip the step in foreach, if the <<FIELD>> is null?

Hi @spisiakmi 

I dont think your isnotnull is matchnig as you expect on "", try this:

| makeresults
| eval tmp_1=1
| eval tmp_2=""
| eval tmp_3=3
| eval tmp=""
| foreach tmp_*
[| eval tmp = tmp.if(<<FIELD>>!="",<<FIELD>>."|","")]
| eval tmp=trim(tmp,"|")
| table tmp
