Is there a way to change the text of a text or tspan node, like the attributes?

Currently, no.

@bitgenerator Text nodes manipulation has been added in the latest commit. Here's an example:

auto data = R"SVG(<svg xmlns="http://www.w3.org/2000/svg">
<text id='a' y='120' font-size='120'> Hello World</text>
</svg>)SVG";

auto document = Document::loadFromData(data);

auto text_element = document->getElementById("a");
auto text_node = text_element.children().front().toTextNode();
text_node.setData("I love SVG!!!");

document->updateLayout();

This should help you modify the text content as needed.

Thanks a lot! I've written a similar function but it's good to have a official change. ;-)
