Reproducible: Always

Steps to Reproduce:
1.Open XML file
2.
3.
Actual Results:  
XML Parsing Error appears and the rendering is stopped.

Display the page as it displays fine in FF2. Or a XML Parsing Error on top then continues to display the page as in FF2 as a backward compatability.

WFM.  When I click the link to the first attachment, I get an unstyled XML page, not an XML parsing error page.

Attachment: required DTD for XML file.

Comment 6

[Jason Foo]

this is getting amusing. think i found where the error lies. 

Is there a limit to the length of file system address that FF3 can process compared to FF2?


This dies...

<?xml version="1.0" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="file:///C:/Program Files/Analog Devices/VisualDSP 4.5/System/linker_map_ss1.xsl"?>
<!DOCTYPE DOCUMENT SYSTEM "file:///C:/Program Files/Analog Devices/VisualDSP 4.5/System/linker_map.dtd">


This works...

<?xml version="1.0" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="linker_map_ss1.xsl"?>
<!DOCTYPE DOCUMENT SYSTEM "linker_map.dtd">

Comment 7

[Jason Foo]

Attachment: The original set of files required to view the XML file.

Comment 8

[Jason Foo]

Attachment: This edited version works fine. Shorter file access?

Comment 9

[Jason Foo]

For the working version. i simply copied a set of the files:
C:/Program Files/Analog Devices/VisualDSP 4.5/System/linker_map_ss1.xsl
C:/Program Files/Analog Devices/VisualDSP 4.5/System/linker_map.dtd

to the working directory and edited the links to local relative linking. 
<?xml-stylesheet type="text/xsl" href="linker_map_ss1.xsl"?>
<!DOCTYPE DOCUMENT SYSTEM "linker_map.dtd">

it possibly have to do with how FF3 parses the lines:
<?xml-stylesheet type="text/xsl" href="file:///C:/Program Files/Analog Devices/VisualDSP 4.5/System/linker_map_ss1.xsl"?>
<!DOCTYPE DOCUMENT SYSTEM "file:///C:/Program Files/Analog Devices/VisualDSP
4.5/System/linker_map.dtd">

I think you're just encountering the new file:/// security restrictions in Firefox 3.  Local files are no longer allowed to read other local files unless they're in the same directory or a subdirectory, and including a dtd counts as reading.  See bug 230606 and bug 402983.

Comment 11

[Jason Foo]

ah. i see. most likely it. 

though same as posters in the other reports. i question the need for such restrictions. is there a way to diable this security feature? i can think of most likely more than one program (this case is VisualDSP++) generates XML or HTML files as report files that would require this function. Web developers too. 

forgive me if the situation has changed. cos i'm only a budding programmer. not so skilled or knowledgable yet.

I was about to post a bug for Firefox 3 beta 5 relating to xml-stylesheet
but I think this is the same issue, so adding a comment here.

any xml file starting with a link to an xsl stylesheet starting with ..
eg

<?xml-stylesheet type="text/xsl" href="../styles/pitest.xsl" ?>

gives a
XML Parsing Error: 
Location: file:///C:/tmp/pitest/xml/pitest.xml
Line Number 1, Column 1:

warning which is pretty confusing (it's not a parse error)
the restriction on the stylesheet being a subdirectory is pretty crippling for distributing documentation to be installed on the user's local machine
(so accessed via file:://) but with a "site wide" styleshete in place, in which case the natural thing (which works in IE, Opera and FF2) is to have a stylesheet near the top of the tree and relative links from the xml files of the form ../path-to-styles-directory/stylesheet.xsl

No reply, INCOMPLETE. Please retest with Firefox 3.6.10 or later and a new profile (http://support.mozilla.com/kb/Managing+profiles). If you continue to see this issue with the newest firefox and a new profile, then please comment on this bug.
