I will look into this, but I can't promise anything before next week.

Thanks for the heads up,

Thanks.  There's no rush.  I will fix expand-file-name so it doesn't
crash with such bogus file names.

A quick analysis.

    file:path

is a valid file link type in Org. Therefore,

    file:///opt/tomcat/4/apache-tomcat-4.1.40/webapps/../user_projects/GHIJSP2/deploy/WEB-INF/sharedfiles/resources/FR/domVal.xml

is parsed as a file link with path:

    ///opt/tomcat/4/apache-tomcat-4.1.40/webapps/../user_projects/GHIJSP2/deploy/WEB-INF/sharedfiles/resources/FR/domVal.xml

This path passes `file-name-absolute-p' predicate, so "ox-html.el"
concatenates "file://" to

  (expand-file-name path)

Since path is absolute, per `file-name-absolute-p', `expand-file-name'
is probably needed for its "and canonicalize it" part.

Note that other export back-ends, like, "ox-md.el", also use this
construct.

FWIW, I don't see any wrong behaviour here (except that "file://" should
probably not be prepended to path in this case).

But that's exactly the problem: producing a file name from a file://
URL requires to remove the "file://" prefix.  It is invalid to leave
the 2 extra slashes and remove only "file:".  Why does Org do that?

Now I'm confused: why are you talking about prepending "file://", when
the problem, as I understand it, happens because "file://" was not
_removed_ from it together with the 2 slashes?

Presumably because Org decided to use "file:" rather than standard
"file://" URI, hence leading to exactly this confusion.

Because Org doesn't know squat about URI schemes and uses ad-hoc parsing
and manipulation rather than splicing it all out according to the spec.

Besides, why is three leading slashes even a problem?  IIRC, POSIX says
that any number of leading slashes (except when starting with exactly
two, which are system dependent and are usually interpreted as a UNC
path) should do exactly the same thing as a single slash.

Achim.

That cannot be right, though, can it?  If Org wants to support
file:/foo, fine, but then it should try the standard file:///foo
before falling back on non-standard forms, I think.  Am I missing
something?

I fixed expand-file-name (trunk revision 116624).  I'm keeping the bug
open until the Org part is either fixed or we decide it doesn't need
fixing.

In my opinion, it needs a fix, but it's quite a rewrite, so don't
expect any change here before Org 9.0.

If someone wants to work on this, help is welcome.

Let's keep the bug open in the meantime.
