Only one xpath result

David_Veld · December 30, 2009, 9:47pm

Hi,

The code below works fine in plex, the only problem is that only one result is shown in plex after I parse the content from break.com into plex.

How is it possible that only one items shows up instead of all the twelve items that are available on the website?

Hi,

This is your issue:


<br />
 for content in videos:<br />
    title = content.xpath("./a/span")[0].text<br />
    thumb = content.xpath("./a/img")[0].get('src')<br />
    summary = content.xpath("./a")[0].get('title')<br />
  for content2 in videos:<br />
    url = content.xpath("./a")[0].get('href')<br />
  dir.Append(Function(VideoItem(PlayVideo, title=title, summary=summary, thumb=thumb), url=url))<br />

Not exactly sure what you are trying to do but the last line, which adds video items to the directory, is not inside the loop. It will only be executed once with last values populated. Indent it to the correct position to get it inside the loop block.

As a second point, what is the point of the second loop? Don't you want:


<br />
for content in videos:<br />
    title = content.xpath("./a/span")[0].text<br />
    thumb = content.xpath("./a/img")[0].get('src')<br />
    summary = content.xpath("./a")[0].get('title')<br />
    url = content.xpath("./a")[0].get('href')<br />
    dir.Append(Function(VideoItem(PlayVideo, title=title, summary=summary, thumb=thumb), url=url))<br />

Thanks for the tip, it worked and I also removed the second loop (I did the second loop because first it would not pick up the fourth xpath in one loop, but now it does). It is all pretty new to me but I am starting to understand it.

Thanks again.

David_Veld · December 30, 2009, 11:03pm

As a last thing. I tried as a test to play a video item but plex keeps saying that it cannot read from the url, what is it?


def Video(sender, url):<br />
<br />
  dir = MediaContainer(title3=sender.itemTitle, art=R(ART), viewGroup="InfoList")<br />
<br />
  videos = XML.ElementFromURL(url, isHTML=True, errors='ignore').xpath(XPATH_VIDEOS)<br />
  for content in videos:<br />
    title = content.xpath("./a/span")[0].text<br />
    thumb = content.xpath("./a/img")[0].get('src')<br />
    summary = content.xpath("./a")[0].get('title')<br />
    url = content.xpath("./a")[0].get('href')<br />
    dir.Append(Function(VideoItem(PlayVideo, title=title, summary=summary, thumb=thumb), url=url))<br />
<br />
  return dir<br />
<br />
####################################################################################################<br />
<br />
def PlayVideo(sender):<br />
  <br />
  dir.Append(Function(VideoItem("http://video1.break.com/dnet/media/2009/12/christmas-carol-of-the-bells-with-dominoes_3.mp4", title="Test")))

If you know the path the URL of the video, you don’t need a Function, you can just add it directly like this:


<br />
dir.Append(VideoItem(url, title=title, summary=summary, thumb=thumb))<br />

David_Veld · December 30, 2009, 11:11pm

Yes i tried that also but it did not work either.

elan · December 30, 2009, 11:14pm

Can you be specific about how it failed? For example, can you paste the resulting XML from the directory in here?

I recommend running the Media Server from the Terminal to watch output, and turning on debug logging in Plex.

David_Veld · December 30, 2009, 11:16pm

In plex it say: “Could not read

and below is the log output:

elan · December 30, 2009, 11:19pm

You’re still using the Function, which isn’t working b/c you’re trying to pass a url argument to it. The function would need to look like this:


<br />
def PlayVideo(sender, url):<br />
  return Redirect(url)<br />

But this is really just evidence that you don't need the function in the first place :-)

David_Veld · December 30, 2009, 11:36pm

Ok, I understand what you say I think, but as a matter of taking small steps I would like to play a predefined video in plex after i scrolled through the generated video list in plex. Later I will create a function that will read the url from the website and then play the video. So I thought that I could define the url of the video and then play it, but that does not work. So how can I play the predefined url in plex within that function, so that, that url plays after each item i click in the generated list in plex.

In this way i can understand the working of it better.

jwray · December 30, 2009, 11:40pm

Fine approach.


<br />
def PlayVideo(sender):<br />
  dir.Append(Function(VideoItem("http://video1.break.com/dnet/media/2009/12/christmas-carol-of-the-bells-with-dominoes_3.mp4", title="Test")))<br />

needs to be


<br />
def PlayVideo(sender, url):<br />
  <br />
  return Redirect("http://video1.break.com/dnet/media/2009/12/christmas-carol-of-the-bells-with-dominoes_3.mp4")<br />

and then PlayVideo needs to be changed to parse the page at the end of url and extract the video link.

David_Veld · December 30, 2009, 11:50pm

Thanks for your help!

jwray · December 30, 2009, 11:52pm

No problem. The days of trying to figure out python (I still dislike indents for block demarcation), Plex, video formats, xpath, etc. at the same time are still fresh in my mind. Once you have the basic concepts down, which your example already has, the rest is pretty straightforward.
