What SVG filter can be used for a task?

Question

Graphic arts

Hey! advise what you can think of, my output is superimposed on the SVG map of icons, text, the second layer is also SVG at c coordinates, and here one field is displayed with multiple values, and each value cannot be wrapped in anything, the value can only be either an id or a label, what can be done is put between any delimiter | , space, etc. but not tags, twig cuts off the infection, now it's output like this

<text x="106929" y="78435" class="fnt0">Russian English</text>

ideally, I need to display a flag icon instead of text, or at least make each word on a new line and not in a line. There can be many values, what can you think of? filters maybe?
<любой код SVG>Russian English</svg>
otherwise it is displayed only in div and html naturally breaks the whole svg :(
