Detailed Description

A python rpm.mi match iterator object represents the result of a database query.

Instances of the rpm.mi object provide access to headers that match certain criteria. Typically, a primary index is accessed to find a set of headers that contain a key, and each header is returned serially.

The rpm.mi class conains the following methods:

To obtain a rpm.mi object to query the database used by a transaction, the ts.match(tag,key,len) method is used.

Here's an example that prints the name of all installed packages:

import rpm ts = rpm.TransactionSet() for h in ts.dbMatch(): print h['name']

Here's a more typical example that uses the Name index to retrieve all installed kernel(s):

import rpm ts = rpm.TransactionSet() mi = ts.dbMatch('name', "kernel") for h in mi: print "%s-%s-%s" % (h['name'], h['version'], h['release'])

Finally, here's an example that retrieves all packages whose name matches the glob expression "XFree*":

import rpm ts = rpm.TransactionSet() mi = ts.dbMatch() mi.pattern('name', rpm.RPMMIRE_GLOB, "XFree*") for h in mi: print "%s-%s-%s" % (h['name'], h['version'], h['release'])
