want to create a Azure Logic App expression

In Azure Logic App, I am creating blob event grid. I am able to get event whenever I have added or deleted a blob from a storage account. In that I am getting the below responses.

enter image description here

In the Subject i am getting response as '/blobServices/default/containers/james/blobs/catputvendor/Capture.PNG'

Now I need to write an expression which gets below result. '/james/catputvendor/Capture.PNG'. Which expression is best.

I got below expression using c# working but in logic app expression, we don't have Remove method. How I need to do in logic app as following:

var subStri1 = str.Remove(str.IndexOf("/blobs"), "/blobs".Length).Substring(str.Remove(str.IndexOf("/blobs"), "/blobs".Length).LastIndexOf("/containers") + "/containers".Length);

The Subject in the Dynamic content, it's the absolute path about the blob. So you could use split expression to get the path you want.

And the expression would be like this:split(triggerBody()?['subject'], '/')?[4]. My subject path is /blobServices/default/containers/firstcontainer/blobs/test/Snipaste_2018-11-13_10-08-08.png. So the expression will get the container name firstcontainer.

So the whole expression will be @{split(triggerBody()?['subject'], '/')?[4]}/@{split(triggerBody()?['subject'], '/')?[6]}/@{split(triggerBody()?['subject'],'/')?[7]}.

Here is my flow and the result page.

Hope this could help you, if you still have other questions, please let me know.
