Python CGI to Display Flickr Images

From: "andrew cooke" <andrew@...>

I am rewriting my website (not yet public) and wanted to include the
latest images from my flickr page.  At first I assumed this would be AJAX,
but it turns out to be simpler to just use an iframe (saves you rewriting
the DOM yourself).

The following code, run as a cgi, pulls details of the last 4 images from
my flickr account and generates the HTML for the iframe.  To re-use you
need to add your own api_key (and change parameters to get the user you

I didn't use XSL because that's not in the standard Python libs and this
has to run on my ISP.


 from httplib import HTTPConnection
 from re import compile

 photos = compile(r'(<photo [^>]+>)(.*)')
 attributes = compile(r'([a-z]+)="([^"]+)"(.*)')

 cnx = HTTPConnection("api.flickr.com")
 rsp = cnx.getresponse()
 if 200 == rsp.status:
     print "Content-type: text/html"
     print """<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
     <link type="text/css" rel="stylesheet" href="index.css" title="default"/>

     xml = rsp.read()
     xml = xml.replace('\r', ' ')
     xml = xml.replace('\n', ' ')
     while xml:
         match = photos.search(xml)
         if match:
             (photo, xml) = photos.search(xml).groups()
             attrs = {}
             while photo:
                 match = attributes.search(photo)
                 if match:
                     photo = match.group(3)
                     attrs[match.group(1)] = match.group(2)
                     photo = ''
             print '<a
 % attrs
             xml = ''
     print """  </body>
