[xslt] Output to stdout is different from output to file

[Rush Manbert <rush manbert com>]

Hi,

I have written a stylesheet that assembles its output from pieces in 
different files by using the document() function (It also applies 
transformations to the included doc contents using "mode" templates). My 
first test was to include a single component. I am using xsltproc to do 
my testing, and when I run it using this command line:
xsltproc --novalid stylesheet.xsl test.xhtm
the correct output shows up on stdout.

However, if I run it using this command line:
xsltproc --novalid -o xform.xhtm stylesheet.xsl test.xhtm
what appears in xform.xhtm is different (and not correct) from what was 
previously output to stdout.

I have searched the archives and didn't see anything like this 
mentioned. Is this a known problem, in the sense that everyone knows 
that you should always redirect stdout to a file if you want the correct 
output? If that's not the case, I can post again and include all of the 
xml and xsl files. (It will be sort of a long post, which is why I'm 
asking this question first.)

If I run "xsltproc --version", it tells me this:
Using libxml 20615, libxslt 10112 and libexslt 810
xsltproc was compiled against libxml 20615, libxslt 10112 and libexslt 810
libxslt 10112 was compiled against libxml 20615
libexslt 810 was compiled against libxml 20615

Thanks,
Rush
