Any ideas? I tried hosting it on Google drive and Dropbox but I get the same errors for both.

Re: Cant parse feed

everytime you open a while, an inf and a for or for each

you have to close it.

try adding a "end for" in line 41 and replace it with the next you have, let me know if that solved your problem.

And actually the compiler tells you the error.. which in this case is: "Syntax Error."

your syntaxis is off, thats because you didnt close a for loop.

Re: Cant parse feed

"Next" is the same as "End For", so it was in the top code posting for the thread.
If categories.kids has something in it then it ought to be ok there...

wouldnt hurt to try the end for anyway hehehe

i didnt know about the next, and i try not to learn specifics about a language like next that i knows its only particular for brightscript.

end for on the other hand i just see it in my mind as a { } hehehe

Re: Cant parse feed

Terse as he was, belltown is correct.
The exact error message is not helpful - but I am fairly sure categories is invalid (to test after this error, in console just type `? type(categories), categories` ).

Luckily we have the reason in console dump too - @lbell, instead of
https://drive.google.com/file/d/0B_qjht ... sp=sharing
try using
https://docs.google.com/uc?authuser=0&i ... t=download
Instead of the original xml file, you were getting some html page to edit the file

Re: Cant parse feed

Yes, at least 3 separate issues here:

1. The xml would not parse because of what EnTerr said. You can see from the debug output that 'categories' is invalid:


Local Variables:
categories &h0010 bsc:roInvalid, refcnt=1

2. Even if it did parse, the 'categories' element contains no 'kids' children, only 'category' children, which is why you need to replace:


for each category in categories.kids

with


for each category in categories.category

(slight correction from what I said in my first reply).

3. Also, since 'title' is an attribute of 'category', not a child element, you cannot get its text from category.Title; you have to use category@title. Even if it were a child element, you still couldn't get the text using category.Title; in that case you'd need category.Title.GetText ()

Re: Cant parse feed

My hosting was bad. My friend let me use his website to host the xml file and everything worked! I didn't have to change the code at all!
Thanks guys!
