Thank you all,I am going through XSLT Programmers Reference from 'Michael
First 2 chapters clarified all my basic doubts about XSLT.
I am very thankful to the author for such a nice book.

One doubt at this stage.I am passing arguments to XSL file using perl
script like this,

my $results = $stylesheet->transform($source,
XML::LibXSLT::xpath_to_string(cnt => "1",idx =>     "$in{'idx'}",new
=> "$in{'new'}"));

In my template rule,I am declaring it,as I want to pass them to next form.
    <xsl:param name="cnt" select="$cnt" />
    <xsl:param name="idx" select="$idx" />
    <xsl:param name="new" select="$new" />

   <form name='myfrm' method='POST' action='logic.cgi'>
        <input type="hidden" name="name_idx" value="{$idx}" />
        <input type="hidden" name="name_new" value="{$new}" />
        <input type="hidden" name="name_cnt" value="{$cnt}" />

In this case,why do I need to declare these using <xsl:param>? Because
without specifying this also,I am able to pass values to next form.

and I can't remember the title, but I couldn't make much out of it. The second
one (by Michael Kay) I'm reading it now in my free time and I can say
everything is as clear as can be for a full beginner like me with no formal
background in computing. I feel thankful to Michael for that.
