My xsl:
----------
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
	<xsl:apply-templates select="First"/>
</xsl:template>

<xsl:template match="First">
	<!--<xsl:for-each select="Section[parentID='0']"> -->
	<xsl:for-each select="Section">
	<xsl:variable name="ID" select="sectionID"/>
	<xsl:value-of select="text"/>
		<xsl:for-each select="../Section[parentID=$ID]">
			<xsl:value-of select="text"/><br/>
			<xsl:variable name="ID" select="sectionID"/>
<!--			currentID = <xsl:value-of select="$ID" />-->
		</xsl:for-each>
<!--		<xsl:variable name="ID" select="sectionID"/>
		sectionid afterloop= <xsl:value-of select="$ID" />-->
<!--		<xsl:variable name="ID" select="text"/>
		text afterloop = <xsl:value-of select="$ID" />-->

	</xsl:for-each>
</xsl:template>

</xsl:stylesheet>


CURRENT OUTPUT:
-----------------
	id 1
	pid 0
	text Section 1

	id 5
	pid 1
	text Section 1.1

	id 10
	pid 5
	text Section 1.1.1

	id 19
	pid 10
	text Section 1.1.1.1


Desired Output
===============
	id 1
	pid 0
	text Section 1

	id 5
	pid 1
	text Section 1.1

	id 10
	pid 5
	text Section 1.1.1

	id 19
	pid 10
	text Section 1.1.1.1

	id 11
	pid 1
	text Section 1.2


I am able to loop through the first part of the xml but when it comes to the 
second part of the subsection i am not getting that output at all.

Can anyone please please help me out.
