php - Sort elements of a wordpress-page by its title/figcaption

one text

I have a wordpress-page (inclduing an individual page-template) with multiple constantly changing figures (only figures) which all have a one-word figcaption. Currently I sort those figures on the page by manually using wordpress' GUI up and down arrows. Is there any chance to edit the default existing code to sort those figures alphabetically by their figcaption? What I currently have has no sorting or differentiation at all:

$content = get_template_part('content', get_post_format());
echo $content; 

Are there any built-in functions/methods to simplify the next steps in wordpress?
