Hide parts of woocommerce product title

Hi,

We use e2pdf to generate many documents from woocommerce.
All my products titles have the same format:
product name > date and place
For some reasons I only display the product name part of the title in front end, with this snippet:

add_filter( 'the_title', 'masquer_partie_titre_produit', 10, 2 );
function masquer_partie_titre_produit( $title, $id = null ) {
if ( (is_product() || is_product_category() || is_shop()) && in_the_loop() && get_post_type( $id ) === 'product' ) {
$parts = explode( '>', $title );
if ( count( $parts ) > 1 ) {
return trim($parts[0]);
}
}
return $title;
}

I would like e2pdf to have the same behaviour. I have tried some code but no result...

Can you help me to do this or give some clues please?

Best regards

Thank you for the quick support, as usual!
Sorry but it doesn't work.

You are right. I had the option "disable WYSIWYG Editor" unchecked, so some characters went wrong after copy paste your code.
Many thanks!!!
