Can anybody provide me the url of invalid RSS feed which can throw a below on of the error:
http://validator.w3.org/feed/docs/
Kindly help out. I need to test one functionality
Validating this url: http://httpbin.org/xml will result in UndefinedElement error. Or you could take any rss feed and add some errors to the markup and past that into the validator.

I am using drafts 5 and would like to convert the markdown into a powerpoint using a callback URL action. It appears like it should be quite straightforwards but Im not getting any success using the following:
makeslides://x-callback-url?input=[[draft]]&type=md&name=mydoc
I just keep getting an error message saying invalid URL generated. Any ideas on how to get this to work?
I manage to get it working when I do two steps, first copy to clipboard and second use the callback URL to makeslides
makeslides://x-callback-url?input=[[clipboard]]&type=md&name=[[title]]
First you must know I'm a total beginner, I'm trying to learn so I almost don't know anything.
On the basic page of the API, there is a curl command used as an example to show us how to make requests.
I'm using Ruby on Rails so I used "curl-to-ruby" website to translate it, but it did not work as expected.
I wanted it to show me this :
uri = URI.parse("REQUEST_URL")
response = JSON.parse(Net::HTTP.get(uri))
Instead I got this :
uri = URI.parse("REQUEST_URL")
response = Net:HTTP.get_response(uri)
I don't understand any of this, I thought I wouldn't need to and just use "curl-to-ruby", but apparently I really need to get this.
Would you please try to explain me ?
Or give me links ?
Or matters to read (curl, API, http) ?
Thank you very much, have a nice day.
It's because that command doesn't return just the content, it returns the whole HTTP response object including headers and body. You need to extract the response body and parse that using JSON.parse(), e.g.
JSON.parse(response.body)
See documentation here: https://docs.ruby-lang.org/en/2.0.0/Net/HTTP.html#method-c-get_response
(Also, there is nothing in the cURL command which would hint to the converter that the content-type of the response was expected to be JSON (e.g. perhaps an "accepts" header or something), so even if it were able to produce extra code adding the JSON.parse part, it has no way of knowing that it would be appropriate to do so in this case.)
We are using Nokogiri to validate XML files using a XSD. The problem is that the error messages that Nokogiri generates are not very friendly and very hard to translate:
"Element '{http://www.portalfiscal.inf.br/nfe}infNFe': The attribute 'Id' is required but missing."
Does anyone know of a parser or any other way to capture the info needed from the error to generate a more human friendly error?
Until then, we will be doing a custom parser for them... ouch!
I created a gem for this that is now open source: https://rubygems.org/gems/xml_errors_parser
It seems to work pretty well so far, but number of errors parsed is very few for now. It is however very easy to add new errors, so we will be adding them as needed.
Code reviews and pull requests are always great :)
Im using url_encoded_fmt_stream_map to get a List of Youtube VideoStream "urls".
I want to use these urls to show Youtube videos in my VideoView.
My method pretty much returns a String Array containing Strings like this:

If you have a close look at it, you can see that this String actually contains valid information. Unfortunately I have no idea how to extract a valid url out of this.
How would I do that?
If I create an URI with the String above and add it to my VideoView, a message "Can't play this video." pops up.
As you probably know, youtube link looks like that:

And as you said, all the parameters we need are shown in your string.
There are 2 important parameters we need to extract from your string: url and signature.
The Link eventually should look like this: url + "&signature=" + sig.
You can take a look at my code, where I extract all the available links out of youtube link. It's wriitten in java for an android app: link
Thank you for your effort.
I solved this problem by sticking to the official YouTube API. Also see this question:
Getting YouTube Video ID including parameters
I have problem getting statistics information from youtube data api. I make a request to http://gdata.youtube.com/feeds/api/videos?q=video_id&alt=json, it works for some, but for some video id, the response does not contain 'entry', 'yt$statistics', 'gd$rating' for example:
zLcbznigfs missing 'entry', aVfN6XjACDY missing 'yt$statistics', fjhQ9Kf4iHk missing 'gd$rating'
After moving around, i found out the solution for this: use &alt=atom instead of using &alt=json, which means that we better read from Atom feed than JSON (and feedparser is an excellent module for doing this). I have checked this with several video id, it works fine.
Hope that help. Thanks.
