Extract specific data from returned string in PowerShell

Question

I am running a command that queries my storage array for a list of items. The output gets stored as follows

$ls_xtrem_clusters = Get-XtremClusters
write-host $ls_xtrem_clusters

This results in the output

@{href=https://192.168.1.1/api/json/v2/types/clusters/1; name=cluster1}

What I am trying to do is get a list of the names only. So if there were 3 clusters, I want an array that contains the values cluster1, cluster2, cluster3. This is dynamic content, so I need to be able to extract the data from the values returned by the Get-XtremClusters command.

I tried this

$ls_xtrem_clusters = Get-XtremClusters
$ls_xtrem_cluster | select-object name | %{write-host $_}

Which gave me

@{name=cluster1}

So my question is, how do I extract cluster1 (or if multiple exist cluster1, cluster2, cluster3) and put it in an array?

In PowerShell 3 or 4, you can possibly do (Get-XtremClusters).Name — TessellatingHeckler

You really don't need the Write-Host bit. What you do need is the -ExpandProperty argument for Select-Object. Try this out:

$ls_xtrem_clusters = Get-XtremClusters
$ls_xtrem_cluster | select-object -Expand name

Thanks, that worked I used this though $my_clusters = $ls_xtrem_clusters | select-object -Expand name foreach ($i in $my_clusters){write-host $i} I am using it that way since I will be adding a numeric value to each entry and created a selectable list. Now I just have to work that bit out.
