Retrieve second parameter from stringCollection

Question

How can I retrieve the second value of stringCollection, like

['Ana', 'Clara]

And output this values in two different claims, e.g:

<ClaimType Id="firstName"/> // Ana
<ClaimType Id="lastName"/> // Clara

I searched for and nowhere describes how split stringCollection into claims, there is a way?

(Documentation explains only about how get the first item)
