sobeks posts in category highlight

Hi!

I am not into php syntax. I need a those 2 lines together.

$text_before = '
<li>'; $text_after = '</li>
'; $text_container_before = ''; $text_container_after = '';

[line of sobeks_posts_in_category.php]

and this:
<?php if ( $post->ID == $wp_query->post->ID ) { echo ' class="current"'; } else {} ?> [a way to highlight posts]

i have tried:
$text_before = '<li if ( $post->ID == $wp_query->post->ID ) { echo ' class="current"'; } else {} >'; $text_after = ''; $text_container_before = ''; $text_container_after = '';

but this is not working.

What i need:
a list of posts of the current category with highlighting
