Challenge

Write a program which, using the XML data from the site here, display the name of the programme which is currently showing on BBC 1.

Information

All times are given at London time (GMT+1 at the time of posting and GMT+0 after the 30th October). Therefore, you should convert your local time to London time.

Each programme is given a start and end time. If the current time is after the start time and before the end time of a programme, that programme is currently showing. Your programme may handle overlaps in anyway you wish.

Your output must be the programme title, like so:

BBC News

However, if the programme has a subtitle (shown by the presence of the subtitle tag), the output should be like so:

Steptoe and Son: The Piano

Where Steptoe and Son is the title and The Piano is the subtitle. An example programme with a subtitle is as follows:

<programme>
    <subtitle>Newcastle</subtitle>
    <title>Flog It!</title>
    <end>1710</end>
    <start>1610</start>
    <desc>
      Antiques series. Paul Martin presents from the Discovery Museum in Newcastle. The items uncovered include a book of autographs with a local connection. Also in HD. [S]
    </desc>
</programme>

URL shorteners are disallowed but XML parsing libraries are allowed.

Winning

The shortest code in bytes wins.

Bash + curl + XMLStarlet, 166 characters

d=`TZ=Europe/London date +%H%M`
curl -s bleb.org/tv/data/listings/0/bbc1.xml|xmlstarlet sel -t -m "//programme[start<=$d and end>$d]" -v title -m subtitle -o :\  -v .

Sample run:

  • \$\begingroup\$ I'm not good at bash scripting , but is it possible to produce the website address via decompressing compressed version of address or something similar ? \$\endgroup\$ – user55673 Aug 22 '16 at 14:27
  • \$\begingroup\$ Not really. Is too short for compression. Uncompressed has 36 bytes, compressed with gzip has 56 bytes. Other tools I tried produce even bigger result. \$\endgroup\$ – manatwork Aug 22 '16 at 14:36

Throws an error when it found the date.

import re,pytz,urllib
from datetime import*
x=urllib.urlopen("http://www.bleb.org/tv/data/listings/0/bbc1.xml").read().split("</p")[:-1]
for m,n in enumerate(re.search("\d*</s",i).group()for i in x):
 if n>datetime.strftime(datetime.now(pytz.utc).astimezone(pytz.timezone('Europe/London')),"%H%M"):print re.search(">.*?</t",x[m-1]).group()[1:-3],": "+re.search("e>.*?</s",x[m-1]).group()[2:-3],_

Please don't hurt me for parsing xml with regex.

    \$\begingroup\$ It's okay, we've only got problems with the parsing of HTML with regex ;) \$\endgroup\$ – Beta Decay Aug 20 '16 at 20:00

    \$\begingroup\$ If I'm not mistaken, I think you can replace the break with something that causes an error (such as 1/0 (or maybe even _)). I'm pretty sure your submissions can exit with an error. \$\endgroup\$ – Loovjo Aug 20 '16 at 20:40
  • \$\begingroup\$ Are third party libs allowed? If yes, then you change urllib to use requests in your first example: x=requests.get(link).text.split("</p")[:-1]. That will save you 2 bytes. \$\endgroup\$ – Zizouz212 Aug 20 '16 at 21:33
  • \$\begingroup\$ @Zizouz212 Yes, requests is allowed \$\endgroup\$ – Beta Decay Aug 22 '16 at 8:59
