Three folders Three output xml file with same input.xs

Hi All,

There are three folders A, B and C which contains xml files in it.
Using XSL, I have to merge xml files from each folder. At the end the output
as A.xml, B.xml and C.xml
Now, here my input xml contains:

Input.xml
<Root>
<file fileloc="A/gen1.xml" />
<file fileloc="A/gen2.xml" />
<file fileloc="B/gen3.xml" />
<file fileloc="B/gen4.xml" />
<file fileloc="C/gen5.xml" />
<file fileloc="C/gen6.xml" />
</Root>

Output should be:
A.xml, B.xml and C.xml

But with the present xsl it's merging A, B and C in one xml file.

My xsl:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output method="xml" indent="yes" encoding="UTF-8" />
	<xsl:template match="/">
		<help>
			<product name="viewer" major_release="10"
minor_release="0">
				<onlinehelp>
					<xsl:for-each select="Root/file">
						<fileloc><xsl:attribute
name="path">
			<xsl:value-of
select="concat(substring-before(concat(substring-before(@fileloc,'/xml/'),'/
html/',substring-after(@fileloc,'/xml/')),'.xml'),'.htm')"/>
						</xsl:attribute>
						<xsl:apply-templates
select="document(@fileloc)/onlinehelp/topic"/>
						</fileloc>
					</xsl:for-each>
				</onlinehelp>
			</product>
		</help>
	</xsl:template>
	
	<xsl:template match="topic">
		<xsl:copy-of select="."/>
	</xsl:template>
</xsl:stylesheet>

If I comment out B and C filelocs, it gives output as A.xml.

Here I have to use Input.xsl and Input.xml transform output as A.xml, B.xml
and C.xml
Can it be possible three folders three output xml file with same input.xml
and input.xsl

Thanks,
Shailesh
