Getting a subset of a tree or table [message #1667495]

Hi Guys, I was trying to retrieve a subset of a table/tree but I could only get one item. How do I get a subset list of items or even just their count from the example below.

index.php/fa/21142/0/

get-item "Infos.*" | get-item ".*duplicated.*" | length // <- this works but of course I can only get one item. How do I retrieve multiple items instead?

cheers!

Joseph

Hello,

You can use the key -index:

get-item "Infos.*" | get-item ".*duplicated.*" -index 0 | length 
get-item "Infos.*" | get-item ".*duplicated.*" -index 1 | length

Please try and let me know if it is suitable for you.

Yours sincerely,
Olga.

HI Olga,

That was quick. That would be suitable but would there be any other way to get them all instead of getting them one by one? At least for my purpose, I'm only interested in the number of items that have the "duplicated" string.

cheers!

Do you want to verify number of "duplicated" strings?
I've found out the following construction for that:

get-item "Infos.*" | get-item ".*duplicated.*" -index 0 
get-item "Infos.*" | verify-error {get-item ".*duplicated.*" -index 1}

It passes if item count is 2. Is it suitable for you?

Yours sincerely,
Olga.

Hi Olga,

Yes that is correct. I only want to get the number of items that have the word "duplicated'.

That one actually works since the items are ordered anyway and those items are on the top of the list.

Do you think select-rows will work for this? I did try to write something with that error but I couldn't get a table object from get-view Problems.

cheers!

Hello,

What kind of problem do you have with getting table object from Problems view?
In order to get it, switch to assertion mode, click on item in table and use "up" and "down" keyboard navigation key as it is described here.
Use the following construction to get number of items:

log [get-view "Error Log" | get-tree | get-table-data | select-rows -column "Message"  -value "duplicated" -match regexp | get rows | length ]

Please try, and let me know if it is suitable for you!

Yours sincerely,
Olga.
