Hi guys, I have another question. If I wanted to process many XML files I
will need to add the document() function. The end result of all this would
be a master index. I have many manuals, each chapter is its own XML file, so
I would like to have one XML file process many XML files and creates one
master index file.

I am not sure how to go about it. Should I use a Key to index all the
indexterms from all the XML files?

Here is my XML file list all the chapters that need to be combined into one
index:

<manual>
	<title>MelChapter1.xml</title>
	<title>Chapter9a.xml</title>
</manual>

Each XML file will have something like this:

<book>
<indexterm name="GMM">Aircraft Logbook Entry</indexterm>
<indexterm name="Smith Airways">MEL Policy and Revision number</indexterm>
<indexterm name="GMM">MX-4 Deffered Items</indexterm>
<indexterm name="E190">Aircraft Tail</indexterm>
<indexterm name="E190">Landing Gear</indexterm>
<indexterm name="Election">Voting</indexterm>
</book>


Here is my XSLT so far with the added Document function. All it does is loop
through each XML but doesnt group all the indexterms into one:

	<xsl:output method="html"/>
	<xsl:variable name="XML1" select="/"/>
	<xsl:template match="/">
		<html>
			<head>
				<title>Manual Index</title>
			</head>
			<body>
				<a name="top"/>
				<xsl:for-each select="$XML1">
					<xsl:for-each select="manual">
						<xsl:for-each
select="title">
							<xsl:variable
name="thetitle" select="."/>
							<xsl:for-each-group
select="document($thetitle)//indexterm" group-by="substring(@name,1,1)">
								<xsl:sort
select="@name"/>

<xsl:variable name="book" select="@bookmark"/>
								<h1>

<xsl:value-of select="current-grouping-key()"/>
								</h1>
								<span
style="font-size:xx-small; color:lightgray; ">
									<p
align="right">

<a href="#top">[Return to Top]</a>
									</p>
								</span>

<xsl:for-each-group select="current-group()" group-by="@name">

<span style="color:blue;">

<xsl:value-of select="current-grouping-key()"/>

</span>

<xsl:for-each select="current-group()">

<xsl:sort select="."/>

<ul>

<span style="font-size:x-small;">

<a href="{$thetitle}{'#'}{$book}">

<xsl:value-of select="."/>

</a>

</span>

</ul>

</xsl:for-each>

</xsl:for-each-group>

</xsl:for-each-group>
						</xsl:for-each>
					</xsl:for-each>
				</xsl:for-each>
			</body>
		</html>
	</xsl:template>

Thanks Again,

Phil

Thanks for the help. This works great in 2.0. I was originally using the
Muenchian method because I was using MSXML with Internet Explorer to
process. This is much easier.

Here is what I used to output to HTML:

Once again...Thanks

As I see it you are using XSLT 1 techniques in an
XSLT 2 stylesheet when XSLT 2 already gives you
what you need as native constructs.

I hope the following use of XSLT 2 facilities helps.
