Hello good people! :)

I want to render parts of a svg file by name but for the life of me I cannot figure out how to do so (using python + gtk).

Here's the svg file in question: http://david.bellot.free.fr/svg-cards/files/SVG-cards-2.0.1.tar.gz

On his site, David, says:

You can draw a card either by rendering the file onto a pixmap and clipping each card manually or by using the card's name through a DOM interface. All cards are embedded into a SVG group.

I don't know what he means by a DOM interface. I have done some searching and the best result I found that seems to fit what I want to do is:

QSvgRenderer *renderer = new QSvgRenderer(QLatin1String("SvgCardDeck.svg"));
QGraphicsSvgItem *black = new QGraphicsSvgItem();
QGraphicsSvgItem *red   = new QGraphicsSvgItem();

black->setSharedRenderer(renderer);
black->setElementId(QLatin1String("black_joker"));

red->setSharedRenderer(renderer);
red->setElementId(QLatin1String("red_joker"));

Notice however that it is for Qt and is not even written in python.

This is what I have so far:

#!/usr/bin/env python

from __future__ import absolute_import

import cairo
import gtk
import rsvg

from xml import xpath
from xml.dom import minidom

window = gtk.Window()
window.set_title("Foo")
window.set_size_request(256, 256)
window.set_property("resizable", False)
window.set_position(gtk.WIN_POS_CENTER)
window.connect("destroy", gtk.main_quit)
window.show()

document = minidom.parse("cards.svg")
element = xpath.Evaluate("//*[@id='1_club']", document)[0]
xml = element.toxml()

svg = rsvg.Handle()
svg.write(xml)

pixbuf = svg.get_pixbuf()

image = gtk.Image()
image.set_from_pixbuf(pixbuf)
image.show()

window.add(image)

gtk.main()

It doesn't work, of course.

What am I missing?
