Re: counting nodes before a certain node

Hi

Thank you for all your response. I am sorry that I haven't been able
to express my problem clearly. I will try it again.
What I need is this:
My input:
<books>
<book>
<title>First title</title>
</book>
<notes>The following books talk about history.</notes>
<notes>For further information please log on to </notes>
<notes>Thank you for choosing.. </notes>
<book>
<title>Abraham Lincoln </title>
</book>

<authors>
sample data

</authors>
<notes>Please call... </notes>
<notes>Copyright Information </notes>
<book>

sample data
</book>
</books>

When I am in the template called book, I want to display all notes
after the first book up to the second book element.

So in my XSLT when I say:

<xsl:template match="books">
		<xsl:apply-templates select="book"/>
	</xsl:template>
	<xsl:template match="book">
		<elem1>
			<title>
				<xsl:apply-templates select="title[1]"/>
			</title>
			<notes>
				<xsl:apply-templates
select="following::notes[following-sibling::*[1][self::book]]"/>
			</notes>
		</elem1>
	</xsl:template>

It selects only the last <notes> element and it selects both the notes
elements right after <book> and after <author>.
Output:
<elem1>
	<title>First title</title>
	<notes>Thank you for choosing.. Copyright Information </notes>
</elem1>
<elem1>
	<title>Abraham Lincoln </title>
	<notes>Copyright Information </notes>
</elem1>
<elem1>
	<title/>
	<notes/>
</elem1>

My desired output is:

<elem1>
	<title>First title</title>
	<notes>The following books talk about history.For further information
please log on to. Thank you for choosing..  </notes>
</elem1>
<elem1>
	<title>Abraham Lincoln </title>
	<notes>Please call... Copyright Information </notes>
</elem1>
<elem1>
	<title/>
	<notes/>
</elem1>

Please let me know if I am more clear now.
