How to override html codes in wordpress?

article id="post-?php the_ID(); ?" ?php post_class( array('list-article', 'clearfix') ); ?

div class="list-article-thumb"
    a href="?php echo esc_url( get_permalink() ); ?"
        ?php
        if ( has_post_thumbnail( ) ) {
            the_post_thumbnail( 'onepress-blog-small' );
        } else {
            echo 'img alt="" src="'. get_template_directory_uri() . '/assets/images/placholder2.png' .'"';
        }
        ?
    /a
/div

div class="list-article-content"
    div class="list-article-meta"
        ?php the_category(' / '); ?
    /div
    header class="entry-header"
        ?php the_title( sprintf( 'h2 class="entry-title"a href="%s" rel="bookmark"', esc_url( get_permalink() ) ), '/a/h2' ); ?
    /header!-- .entry-header --
    div class="entry-excerpt"
        ?php
            the_excerpt();
        ?
        ?php
            wp_link_pages( array(
                'before' = 'div class="page-links"' . esc_html__( 'Pages:', 'onepress' ),
                'after'  = '/div',
            ) );
        ?
    /div!-- .entry-content --
/div

this is the code.

I need override all codes inside

div class="list-article-content"
/div

because html codes are not surrounded by if(!functionname()){}

I don't know how to override this code.

I tried to copy and paste into functions.php in child theme but it just duplicated html code.

So, how to override this html code to child theme without editing parent theme?
