# weglot\_replace\_link

This filter lets you modify the DOM while Weglot replaces links. It receives the DOM string being processed and must return it.

```php
add_filter( 'weglot_replace_link', 'custom_weglot_replace_link' );
function custom_weglot_replace_link( $dom ) {
    // Modify $dom here.
    return $dom;
}
```
