Re: [xsl] Strange Problem with document($variablename)

[Torsten Schlabach <TSchlabach@xxxxxxx>]

Jeni,

<xsl:variable name="filename"
              select="concat('../content/news/', @name)" />

Thank you. That at least make the code more efficient. I had overlooked
that.

Right. It doesn't.

It is. This is why I need to prefix this with ../ to get out of the
stylesheets directory. Again, thank you for the hint, 

>>  document($filename, .)

is again much more elegant.

BUT this does not touch the original problem. It is the *path* at which the
file is being sought. The actual filename piece is lost somewhere, but
*only*
if the concatenated pathname starts with anything else than either the /
character or an alphanumeric character. If it is trying to open the file
"../content/news" instead of "../content/news/foo.html" it is not going to
find it.

I look as if something in between the stylesheet and the actual file system
call is trying to interpret the path against anyhting and gets this wrong. I
need to admin I am running this in Cocoon. Might cocoon be fooling me here?
How would I be able to debug this?
