Hi,

Thanks for your mail. What you have mentioned about
ascending/descending order that thing I know. If I
write the statement 

<xsl:sort select="@category" order="descending"/> then
ouput will come as category 6, 5 , 4, 3......

For ascending it will come as category c1, c2,
c3.......

But I want to select the category at random order not
as ascending or descending order. Suppose there are 6
categories in 

books.xml file. Now I want to select only 3 categories
in ouput file ( e.g in html) and their position will
be different - 

such as 4th (category="c4" in xml doc) will come at
1st position (in html doc), 6th (category="c6" in xml
doc) will come at 

2nd position (in html doc) and 2nd (category="c2" in
xml doc) will come at 3rd position(in html doc).


books.xml
----------

<?xml version="1.0"?>
<books>
	<book category="c1">
		<title>1st Book</title>
		<auth>Author 1</auth>
	</book>

	<book category="c2">
		<title>2nd Book</title>
		<auth>Author 2</auth>
	</book>
	<book category="c3">
		<title>3rd Book</title>
		<auth>Author 3</auth>
	</book>
	<book category="c4">
		<title>4th Book</title>
		<auth>Author 4</auth>
	</book>
	<book category="c5">
		<title>5th Book</title>
		<auth>Author 5</auth>
	</book>
	<book category="c6">
		<title>6th Book</title>
		<auth>Author 6</auth>
	</book>
</books>



books.xsl
----------

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

	<xsl:template match="/">
		<html>
			<head>
			</head>
			<body>
				<table border="1" width="60%" align="center"
cellpadding="0">
					<xsl:apply-templates/>
				</table>
			</body>
		</html>
	</xsl:template>


	<xsl:template match="books">
		<xsl:for-each select="//book">


			<xsl:choose>

				<xsl:when test="@category='c4'">

					<tr>
						<td align="center">
							<xsl:value-of select="title"/>
						</td>
						<td align="center">
							<xsl:value-of select="auth"/>
						</td>
					</tr>
				</xsl:when>


				<xsl:when test="@category='c6'">

					<tr>
						<td align="center">
							<xsl:value-of select="title"/>
						</td>
						<td align="center">
							<xsl:value-of select="auth"/>
						</td>
					</tr>
				</xsl:when>


				<xsl:when test="@category='c2'">
					<tr>
						<td align="center">
							<xsl:value-of select="title"/>
						</td>
						<td align="center">
							<xsl:value-of select="auth"/>
						</td>
					</tr>
				</xsl:when>
			</xsl:choose>
		</xsl:for-each>
	</xsl:template>
</xsl:stylesheet>



books.html
----------

Current Output
--------------


Category		Author
--------		-------

2nd Book		Author 2

4th Book		Author 4

6th Book		Author 6


Expected Output 
---------------


Category		Author
--------		-------

4th Book		Author 4

6th Book		Author 6

2nd Book		Author 2
