Status: RESOLVED INACTIVE

(Firefox Graveyard :: RSS Discovery and Preview, defect)

Description

[Steven]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.0.6) Gecko/2009011913 Firefox/3.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.0.6) Gecko/2009011913 Firefox/3.0.6

Firefox refuses to parse RSS-XML documents where <enclosure url="" /> does not begin with http:// or ftp://

Reproducible: Always

Steps to Reproduce:
1.Create a XML document
2. load XML in Firefox and IE
3. Compare difference in parsing
Actual Results:  
Firefox does not load the XML document while IE does

Expected Results:  
Firefox should still parse and display the RSS-XML document correctly regardless of the url used in <enclosure url="" /> tags

Consider these example XML documents...

Firefox refuses to parse this example:

<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0">
  <channel>
<item>
      <title>test.sc</title>
      <link>\\dmex-pc\files\projects\test.msi</link>
      <description>None</description>
      <pubDate>Thu, 13 Mar 2008 02:06:00 GMT</pubDate>
      <author>Admin</author>
      <enclosure url="\\dmex-pc\files\projects\test.msi" length="492" type="application/octetstream" />
    </item>
  </channel>
</rss>

Filefox does not parse this link even though it begins with http://..IE does completely parse the document however:

<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0">
  <channel>
<item>
      <title>test.sc</title>
      <link>\\dmex-pc\files\projects\test.msi</link>
      <description>None</description>
      <pubDate>Thu, 13 Mar 2008 02:06:00 GMT</pubDate>
      <author>Admin</author>
      <enclosure url="http://dmex-pc\files\projects\test.msi" length="492" type="application/octetstream" />
    </item>
  </channel>
</rss>

Firefox however will parse this document correctly but IE doesn't know how to handle File:// links" 

<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0">
  <channel>
<item>
      <title>test.sc</title>
      <link>\\dmex-pc\files\projects\test.msi</link>
      <description>None</description>
      <pubDate>Thu, 13 Mar 2008 02:06:00 GMT</pubDate>
      <author>Admin</author>
      <enclosure url="file://dmex-pc\files\projects\test.msi" length="492" type="application/octetstream" />
    </item>
  </channel>
</rss>

Sucessfull parsing of these examples by Firefox completely depends on the text provided in the <enclosure url=" /> tags

While RSS spec compliance isn't a particularly interesting goal, if we chose it in this case, we would only treat http (or, depending on our interpretation of "The url must be an http url.", http and https) as acceptable url values.
