Hello,  using the below example that provides some fail-safe redundancy if original file location no longer exists;

result = parseXmlDocument ("http://patebin.com/raw/qerberbb")
  'If there's no content, the result will be empty, so we try parsing another link
  if result.count() < 1 then result = parseXmlDocument ("http://myserver.com/xml.xml")
  if result.count() < 1 then result = parseXmlDocument ("pkg:/xml/categories.xml")
  'Error message if all links fail
  if result.count() < 1 then uiFatalError ("Channel", 40, "Unable to parse Xml document")
uiDisplay (result) 

Thank you

There's no way to tell without knowing what your function getStreamId does.  If it returns an roArray, and if that roArray always contains at least one element except in the error case you are trying to detect, then your code should work.

You need to post the whole function.  The important part is the return statement, but you didn't show that.

Well, the last line before the return is unconditionally pushing an empty string onto the array, so the array size will never be zero even if the URL transfer fails.  I'm not completely understanding the logic, but you need to determine whether, when the URL fails, you want the array to be empty or to contain one empty string.  If the latter then you need to adjust your count test accordingly.
