How I can target this web element using xpath?

I have this element :

<a> < </a>

This CSS selector was working

a:contains('<') 

But for learning I tried to use the following xpath but without success

//a[text()='<']
//a[normalize-space(text())='<']
//a[contains(text(), '<')]

How I can do that with xpath ?

Not sure that xpath is available in the text editor. I belive it must be a valid JS selector.

This is working for me:
a[Text=">"]
