How to display a tab in view profile override

I'm overriding the View Profile render function to produce my own layout.

The only example of I can find load tab content from positions, like $this->userViewTabs.

I need to be able to isolate a tab from within tabmain and then pull out just that tab.

Thanks,

Sorry, just to be clear, the tab I want to load is being output to raw HTML.

I don't need any of the other tabs around it.

You can't isolate a specific tab from that as it's just a raw string of all the tabs HTML. If you're wanting a specific tab you can use a substitution in a delimiter field to render it anywhere on profile you want using the below.

[cb:usertab tab="##" /]

Alternative is to move the tab to a position where only it is present then render that position.
