Replace text of produced Spans

[omarsamir27]

I would like to know if there is a way to modify the str member of a Span , what I basically need to do is modify the text of certain rules if they are present and preserve the Node structure.
I can do this with regex but I want to avoid the cost after already parsing

i kind of achieved what i want by searching through the nodes for the specific Rule and used its Span start and end positions to edit the original text
I will leave this open so if someone has a better solution anyone can benefit from
