Michele may have hit the nail on the head, here, but some other
issues are raised.
0) I don't think the @version and @indent attributes of <xsl:output>
make much sense when method=text. (And I'll ask that wiser folks
than me post a correction if I'm wrong on that.)
1) The OP's XSLT is not well-formed. (There is an extraneous end-tag
for <xsl:variable> lying around.)
2) I'm not 100% sure what `dir` does in Windows, but I'll bet it
would list the files that end in '.xml'. This program also tries
to *read* and *parse* those files. So whereas `dir` will happy
list a file that is not really XML so long as it has a .xml
extension, this program will entirely fail if any one of the
files found in the same directory as the XSLT program ends in
'.xml' but is not well-formed XML. (Which may, of course, be the
desired behavior. In which case one might be better off using
`xmlwf`. :-)
3) This program spits out the URL of each selected file, not its
name (or path & name). On my (GNU/Linux system running Saxon 9
HE) that means that each file's output line will start with
"file:". And it also has implications for character escaping
(i.e., what happens if a space or solidus or whatever is in the
file's name -- here you get %-sign escaping, but I doubt `dir`
does that).
4) This program reads in an input file, but then summarily ignores
it when choosing the directory to list. I can't help but wonder
if OP wants a list of the .xml files in the same directory as the
XSLT program (which is what this program gives me when I run it
w/ Saxon), or would prefer a list of the .xml files in the same
directory as the input document.
=========
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
exclude-result-prefixes="#all">
<xsl:output method="text" encoding="UTF-8"/>
<xsl:template match="/">
<xsl:text>
----- XSLT program file's directory -----</xsl:text>
<xsl:for-each select="collection('.?select=*.xml')">
<xsl:text> </xsl:text>
<xsl:value-of select="document-uri(.)"/>
</xsl:for-each>
<xsl:text>

----- XML file's directory -----</xsl:text>
<xsl:for-each select="collection( concat( replace( base-uri(/),
'/[^/]+$',''),'?select=*.xml'))">
<xsl:text> </xsl:text>
<xsl:value-of select="document-uri(.)"/>
</xsl:for-each>
<xsl:text>
</xsl:text>
</xsl:template>
</xsl:stylesheet>
If I read this right, it looks like you just want to generate a
list of the XML files in a directory, is that correct? If you’re in
a windows enviroment the “dir” command will do what you want.
