item.name() doesn't work.

I couldn't sleep, so i looked at some snippets in satsolver-bindings.

What works now is this (don't blame me, I'm learning ;) ):    (all in 
python-bindings)
Import the remote repo with libzypp. Load the solv file with satsolver. Get the 
values i want.
It looks like this:

import zypp
import satsolver
zy         = zypp.ZYppFactory_instance().getZYpp()
mytemppath = zypp.Pathname( "/tmp/a" )
zy.initializeTarget( mytemppath )
myrepoinfo = zypp.RepoInfo()
myrepoinfo.addBaseUrl( zypp.Url( "http://localhost/software/base_factory"; ))   
# local obs instance output
myrepoinfo.setAlias( "software" )
myrepoinfo.setEnabled( True )
myrepoinfo.setType( zypp.RepoType.RPMMD )
myrepoinfo.setGpgCheck( False )   # not yet implemented . i would need this atm 
: ZYPP_KEYRING_DEFAULT_ACCEPT_ALL=1
myrepomanageroptions = zypp.RepoManagerOptions( mytemppath )
myrepomanager = zypp.RepoManager( myrepomanageroptions )
myrepomanager.addRepository( myrepoinfo )
myrepomanager.refreshMetadata( myrepoinfo )
myrepomanager.buildCache( myrepoinfo )
myrepomanager.loadFromCache( myrepoinfo )
for item in pool:
    print item.string()      # e.g. 
U__s_(213)cairo-doc-1.4.14-20.2.i586(software)
    print item               # e.g. <zypp.PoolItem; proxy of <Swig Object of 
type 'zypp::PoolItem *' at 0x708860> >

# i had no idea how to proceed from here    /me blind  watching doxygen pages 
and stuff like  ^^^^^
# then i looked at satsolver and discovered 
/tmp/a/var/cache/zypp/solv/software/solv 
# so if someone could show me how to do this with libzypp - he would be my hero 
of the day ;)

mysatpool = satsolver.Pool()
tmprepo = mysatpool.add_solv("/tmp/a/var/cache/zypp/solv/software/solv")
tmprepo.set_name("myhackrepo")
mysatpool.prepare()

for solv in mysatpool:
    print solv
    print "Name       :  "+str(solv.name())
    print "Version    :  "+str(solv.evr())
    print "Group      :  "+str(solv.attr("solvable:group"))
    print "Summary    :  "+str(solv.attr("solvable:summary"))
    print "Description:"
    print solv.attr("solvable:description")

# These are the values I wanna use atm. 

Thanks!

Best regards
