Data::Stag::HashDB is a perl used for building indexes over Stag files or objects. SYNOPSIS # parsing a file into a hash my $hdb = Data::Stag::HashDB->new; $hdb->unique_key("ss_details/social_security_no"); $hdb->record_type("person"); my $obj = {}; $hdb->index_hash($obj); Data::Stag->parse(-file=>$fn, -handler=>$hdb); my $person = $obj->{999-9999-9999}; print $person->xml; # indexing an existing stag tree into a hash my $personset = Data::Stag->parse($fn); my $hdb = Data::Stag::HashDB->new; $hdb->unique_key("ss_details/social_security_no"); $hdb->record_type("person"); my $obj = {}; $hdb->index_hash($obj); $personset->sax($hdb); my $person = $obj->{999-9999-9999}; print $person->xml; You need to provide a record_type - this is the type of element that will be indexed You need to provide a unique_key - this is a single value used to index the record_types For example, if we have data in the stag structure below, and if ss_no is unique (we assume it is) then we can index all the people in the database using the code above publicinfo: persondata: person: ss_details: social_security_no: name: address: There is a subclass of this method callsed Data::Stag::StagDB, which makes the hash persistent.
