Can I use a Shortcode output as an HTML attribute value?

Question

Can I use a Shortcode output as an HTML attribute value?

Within a span, the shortcode output works:

span[sola_testimonials_count type='all']/span

Result:
span5,205/span

But as an attribute value, it doesn't get parsed:

span data-value="[sola_testimonials_count type=\'all\']"/span

Result:
span data-value="[sola_testimonials_count type=\'all\']"/span

This is a third-party plug-in, but I obviously have the code and can manipulate it. Is there a way I can get the shortcode to parse as an HTML attribute value? I'm not a Wordpress developer so forgive me if this is an obvious answer.

Many thanks!

This is not exactly what you are asking but maybe can help to find the solution

/* this simulates your shortcode [sola_testimonials_count type='all'] */
function num_sc( $atts ) { return '5,205'; }
add_shortcode( 'num', 'num_sc' );

/* use like this [test]...[/test] to obtain <span data-value="5,205">...</span> */
function test_sc( $atts, $content = null ) {
    remove_filter( 'the_content', 'wpautop' );
    $content = apply_filters( 'the_content', '<span data-value="[num]">' . $content . '</span>' );
    add_filter( 'the_content', 'wpautop' );
    return $content;
}
add_shortcode( 'test', 'test_sc' );

Result

/* INPUT */
AAA [test]this is a test[/test] BBB
/* OUTPUT HTML */
AAA <span data-value="5,205">this is a test</span> BBB

I realize this thread is from January, but I just wanted to briefly point out that, as documented in the codex, shortcodes are allowed inside html attributes.

I am not good at Regex but do_shortcode will basically will not parse any shortcode in the attributes, this might help you out:

add_filter('the_content', function($c){
    $pattern = '/<span\s*(.*?)data-value=["\']?\[(.*?)\]["\']?\s*(.*?)>\s*(.*?)\s*<\/span>/si';
    $c = preg_replace_callback($pattern, function($c){
        return isset( $c[2] ) ? str_replace(
            $c[2],
            do_shortcode("[{$c[2]}]"),
            $c[0]
        ) : array_pop($c);
    }, $c);
    return $c;
});
