How to import/export Radio Station list of Rhythmbox?

Is it any way to import/export Radio Station list of Rhythmbox?

If not, could you please suggest me any good music player which has similar functionality like Rhythmbox?

Thank you!

rhythmbox stores information about all music-files in ~/.local/share/rhythmbox/rhythmdb.xml

Entries concerning radiostations start with "entry type iradio".

here's a python script to do the same thing, i.e. extract names and locations of internet radio stations from the xml data base used by Rhythmbox:

import xml.sax.handler
import xml.sax
import pprint

class RhythmboxPlaylistHandler(xml.sax.handler.ContentHandler):
    def __init__(self):
        self.inRTitle = False
        self.inRLocation = False
        self.entrytype = "undefined"
        self.titlebuffer = ""
        self.locationbuffer = ""
        self.radiostations = {}

    def startElement(self, name, attributes):
        if name == "entry":
            self.entrytype = attributes["type"]  # we're interested in type="iradio"
        elif name == "title" and self.entrytype == "iradio":
            self.inRTitle = True
        elif name == "location" and self.entrytype == "iradio":
            self.inRLocation = True

    def characters(self, data):
        if self.inRTitle:
            self.titlebuffer += data
        elif self.inRLocation:
            self.locationbuffer += data

    def endElement(self, name):
        if name == "title":
            self.inRTitle = False
        elif name == "location":
            self.inRLocation = False
        elif name == "entry" and self.entrytype == "iradio":
            self.radiostations[self.titlebuffer] = self.locationbuffer
            self.titlebuffer=""
            self.locationbuffer=""

parser = xml.sax.make_parser(  )
handler = RhythmboxPlaylistHandler(  )
parser.setContentHandler(handler)
parser.parse("work_copy_of_rhythmdb.xml")
pprint.pprint(handler.radiostations)

rstations=handler.radiostations

rskeys=[key for key in rstations]
rskeys.sort()

ofile=open("rhytmbox_current_internet_radiostations.txt","w")
ofile.write("#   {0:41}  -->  {1}\r\n".format('radio station name','location'))
ofile.write("#"+120*'-'+"\r\n")
for key in rskeys:
    ofile.write("{0:45}  -->  {1}\r\n".format(key,rstations[key]))
ofile.close()
