Hi,
Here's the URL with which one a get a 404 :
www.mysite.com/section/category/232-a-name
And that's where I have to redirect it :
www.mysite.com/section/category/a-name
(it is also true for www.mysite.com/section/anothercategory/subcategory/527-a-anothername
So actually, I just have to remove the ID (232 or 527) and the dash (-) to have my URL working.
So I have thought about something like this :

From URL :
^/section/{path}/{query}
To URL :
{scheme}://{siteurl}/section/{path}/??

Of course, the "??" is because I just don't know what to write here... Any suggestion ?

I have found this www.selfget.com/forum/redj/1231-replacing-item-1234.html#5002
and tried this :

From URL :
^/section/
To URL:
{scheme}://{siteurl}{path}/{preg_match 1}/[0-9]+-(.*)$/{/preg_match}

And that gave me a
www.mysite.com/section/category/232-a-name/a-name/a-name/a-name/∞
I think the /232-a-name is included in the {path}, but I can't find out how to remove it.

For example, I tried a :
{scheme}://{siteurl}/section/{pathrtrim [0-9]+-(.*)}/{preg_match 1}/[0-9]+-(.*)$/{/preg_match}
But it didn't give any result.

And for the loops at the end, I just can't see.
Any suggestion ?

Hi Luigi,
Thanks for the 'How to'.
A made some changes to fit my needs...

From URL
I added some regex to be sure that the redirection will apply on items and not list views (/section - section/category - section/category/subcategory are Search & List view from Seblod). So it give :It works well - I'm just not sure if it is the simplest way...
BTW, I found a really good tool to help who like me are just discovering regex :
regex101.com
Really helpful to see what the regex is actually selecting in your string with clear explanation. 2 Thumbs Up for this one
