How to remove links from the post content?

@iul,
Tee link is built in the _loop.php file of the theme, inside the <h2> div.
Change

<a href="<?php the_permalink(); ?>" title="<?php printf( __('Permalink to %s', 'twentyten'), the_title_attribute('echo=0') ); ?>" rel="bookmark"  <?php $this->classes('nopmb entry-title_a'); ?>>
<?php $this->the_title(); ?>
</a>

into :

<?php $this->the_title(); ?>

Note : you should do this in a custom theme to avoid losing your modifications by next plugin update.

[Edit] OUps, I guess it’s NOT your question… I leave it anyway, it might help someone else…

@iul

Maybe have a look at PHP strip_tags, where you must then declare which tags are NOT to be stripped… can be laborious …

Also seen :

$link = str_replace("<a href=\"","",$your_link);
$link = ereg_replace("\">()</a>","",$link);

But it will strongly depend on other attributes : title, target, rel, style, …
