Get some feeds. NB wget's O option (and that's a CAPITAL O), allows to save to a reasonable filename of your choice.
wget http://www.openclipart.org/media/feed/rss/woman -O woman.xml wget http://www.openclipart.org/media/feed/rss/man -O man.xml
Creating a simple HTML page from the feed
import codecs, sys, lxml.etree
# Open the filename given on the command line
f = codecs.open(sys.argv[1], encoding="utf-8")
# Read in the XML file
doc = lxml.etree.parse(f)
# This is a Python dictionary containing
# the xml "namespaces" that we may use
NS = {
'media': 'http://search.yahoo.com/mrss/',
'dc': 'http://purl.org/dc/elements/1.1/',
'cc': 'http://creativecommons.org/ns#',
'atom': 'http://www.w3.org/2005/Atom',
}
# Loop over the item elements
for item in doc.xpath("//item"):
svg = item.xpath(".//enclosure/@url")[0]
thumbnail_url = item.xpath(".//media:thumbnail/@url", namespaces=NS)[0]
creator = item.xpath(".//dc:creator/text()", namespaces=NS)[0]
title = item.xpath(".//title/text()")[0]
link = item.xpath(".//link/text()")[0]
print """<div>
<a href="{1}"><img src="{2}" />{0}</a>
</div>""".format(title, link, thumbnail_url)
