Here's some pseudocode for a simple algorithm:

create a stack of booleans

set the last position to the start of the text

search for the opening and the closing spans and for each one found:
    append the text since the last position up to the start of the found item to the output

    if the found item is an opening span:
        if the found item has attributes:
            // it's an opening span with attributes
            // we want to keep it
            push true onto the stack
            append the item to the output
        else:
            // it's an opening span without attributes
            // we want to drop it
            push false onto the stack
    else:
        pop the top boolean from the stack
        if the popped boolean is true:
            // the corresponding opening span had attributes
            // we want to keep this closing span
            append the found item to the output

    set the last position to the end of the found item

append the remaining text since the last position to the output
