You could try using group-ending-with="close" then you will have a group of items, the last of which will always be a close element.

If I write group-ending-with="close" then this will group based on first occurence of <close>.In the given case, there can be more than one <close>....</close>. I want to end my group where a <close> is followed by <book.content> and that can happen after 2-3 occurences of <close>.

Also, is it correct that we cannot use both group-starting with and group-ending-with together, as they are mutually exclusive. Because, if there are some other elements apart from <book.content> and <close> then I don't wish to group them. Like in given example I wdon't wish to group <myname> node.

For example: In this case I want to leave <myname>Trishla</myname> as it is and would like to wrap all occurences of <book.content> and <close> in one big wrap called <book.content> with the condition that the big wrap will close wherever a <book.content> is preceded by <close> and after that a new <book.content> will start.

<books>
<myname>trishla</myname>

<book.content>
   <Topic>ABC</Topic>
   <author>123</author>
</book.content>

<book.content>
   <Topic>DEF</Topic>
   <author>456</author>
</book.content>

  <close>
    <Index>aaa</index>
     <pages>111</pages>
      <Noname>
       <useless>one</useless>
      </Noname>
  </close>

  <close>
    <Index>bbb</index>
    <pages>222</pages>
  </close>

  <book.content>
    <Topic>GHI</Topic>
    <author>789</author>
  </book.content>
<books>

Output:
<books>
<myname>trishla</myname>

<book.content>
   <Topic>ABC</Topic>
   <author>123</author>
<s></book.content></s>

<s><book.content></s> <Topic>DEF</Topic>
   <author>456</author>
<s></book.content></s>
  <close>
    <Index>aaa</index>
     <pages>111</pages>
      <Noname>
       <useless>one</useless>
      </Noname>
  </close>

  <close>
    <Index>bbb</index>
    <pages>222</pages>
  </close>
</book.content>

<book.content>
    <Topic>GHI</Topic>
    <author>789</author>
</book.content>
<books>

OK, I'm still not sure if you want these 'other' elements in, or out of the book.content elements, but hopefully this will give you some ideas to play around with.

Code:

<xsl:for-each-group select="book.content | close" group-ending-with="close[following-sibling::node()[1] = self::book.content]">
<book.content>
  <xsl:apply-templates select="current-group()"/>
</book.content>
</xsl:for-each-group>
