Piping curl and xsltproc
 

Hi,

I'm trying to feed a downloaded XML to an XSLT transform via the command line. When I do it like this:

curl -s http://www.cbr.ru/scripts/XML_daily.asp >rate.xml
xsltproc rate.xslt rate.xml

it works. When I try to pipeline the two together:

curl -s http://www.cbr.ru/scripts/XML_daily.asp | xsltproc rate.xslt /dev/stdin

I get an error message from xsltproc:

/dev/stdin:1: parser error : Document is empty

^
/dev/stdin:1: parser error : Start tag expected, '<' not found

^

I thought the two commands should be equivalent. Please, what's going on here? Not that I cannot solve the problem - I can, it works with an intermediate file. But there's apparently an aspect of pipelining that I don't yet understand.

xsltproc(1) says "It will use the standard input if a filename provided is -".

Try replacing "/dev/stdin" with a dash.
