Uh, just to point out a few things you've said.
Maybe doing it with a trick (by using /hsave and /filter or something)
No one even talked about saving the hash table.
I'm currently want to remove all items which has something* in thier data, but I have to use a while loop which scans the table using hfind (in order to get the item) and then I delete it.
So I'm quite aware of what you *were* trying. And I offered other ways to do it. You said maybe with an /hsave and /filter trick. So I looked into /hsave.
Now, since I've never messed with filter, you've made me look into it within the time I wrote this post.
/hsave -io hash_table_name file.ini section
/hdel -w hash_table_name *
/filter -xff file.ini newfile.ini *delete*
/hload -i hash_table_name newfile.ini section
This will exclude any lines containing "delete" (so make sure your item names don't match the stuff you want to delete in the data)
Edit: Sheesh.. typoes galore..
