/**
* conversion
*
* Conversions enable you to change / adapt the content of each _record field for your needs.
* General syntax is: pattern1 |> replacement1 || ... || patternN |> replacementN
* If the pattern-part of a pair is ommited it will match everything ('^.*$'), which
* is only usefull for the last pair, as they are worked from left to right.
* Example: 1|>private||public
* This will translate a '1' in the _record field to 'privat' and everything else to 'public'.
*
* In addintion to the fields assign by the pattern of the reg.exp.
* you can use all other _record fields, with the syntax |[FIELDINDEX].
* Example:
* Your record is:
* array( 0 => Company, 1 => NFamily, 2 => NGiven
* Your conversion string for field 0 (Company):
* .+|>|[0]: |[1], |[2]|||[1], |[2]
* This constructs something like
* Company: FamilyName, GivenName or FamilyName, GivenName if 'Company' is empty.
*
* Moreover the following helper functions can be used:
* cat(Cat1,...,CatN) returns a (','-separated) list with the cat_id's. If a
* category isn't found, it will be automaticaly added.
*
* account(name) returns an account ID, if found in the system
* list(sep, data, index) lets you explode a field on sep, then select just one part (index)
*
* Patterns as well as the replacement can be regular expressions (the replacement is done
2011-03-09 19:18:26 +01:00
* via str_replace).
