[1]Is it possible to iterate a htable without using "keys" like an array? [2] Is it possible to search for "keys" using regxp? -- -Cheers -Arif

there is no possibility to iterate the hash table from configuration file. The structure is stored in memory, with locks per slots, to be optimized for parallel processing. For a consistent iteration, the lock has to be at hash table level, which will impact the performances a lot. An alternative would be to add iteration still using the locks on slots, but that means new items can be added/removed/updated in other slots while walking on a slot. So it is not like taking a snapshot of hash table content at a specific time. Also, maybe you can provide more details about what you need to achieve, there could be other options to try.

[2] Is it possible to search for "keys" using regxp?

It is possible to count items by regular expression matching on key or value, see: - http://www.kamailio.org/wiki/cookbooks/4.1.x/pseudovariables#shtcn_htable_e… As well as deleting items: - http://kamailio.org/docs/modules/stable/modules/htable.html#htable.f.sht_rm… Cheers, Daniel
