Can anybody let me know how to extract "footnote" from paragraph and write it to end of the section.

This is an exercise in my class for creating end notes from footnotes.

Below is what I am trying to do

Input
<section>
<para>111...<footnote label="1" id="f1"><para>First fnt</para></footnote> 222... <footnote label="2" id="f2"><para>second fnt</para></footnote> </para>
<para>333...<footnote label="3" id="f3"><para>Third fnt</para></footnote> ...</para>
</section>

Required Output
<level>
<para>111....222 ....  </para>
<para>333... ...</para>
<footnote label="1" id="f1"><para>First fnt</para></footnote>
<footnote label="2" id="f2"><para>second fnt</para></footnote>
<footnote label="3" id="f3"><para>Third fnt</para></footnote>
</level>

<xsl:template match="section">
<level>
<xsl:apply-templates/>
<xsl:if test="descendant::*[self::footnote]">
<xsl:apply-templates select="descendant::*[self::section//footnote]"/>
</xsl:if>
</level>
</xsl:template>

<xsl:template match="para">
<xsl:copy>
<xsl:apply-templates select="descendant::*[not(self::footnote)]"/>
</xsl:copy>
</xsl:template>

Your problem is trying to do too much imperatively rather than declaratively. You are treating this like a programming language rather than a templating language.

BTW, your <xsl:if> isn't required because if there are no descendants, then nothing gets pushed.

Also, I feel your predicates are misleading and lengthy, and can be expressed far more succinctly.

In the solution below I'm using modes so that footnotes are handled in two different ways at two different times. Note how I'm "letting things happen" with the template rules, rather than "forcing things to happen".

I hope this helps.
