[xsl] Problem setting ENDTAG in new XML Document

[nikken@xxxxxxxxxx]

I want to convert an existing XML Document to an other XML Document using
XSLT. The new Document
sould include new Group-Main-Tags with the following rule:
AAA -> Group1 (AAB and AAC) repeat:0..n 
BBB -> Group2 (subtag of Group1, with BBA,BBC) repeat:0..n

The Source-Document looks like this:
====================================
<MAIN>
	<MSG>1.0</MSG>
	<ORG>2.0</ORG>
	<AAA>3.0.0</AAA>
	<AAB>3.0.1</AAB>
	<AAC>3.0.2</AAC>
	<BBB>4.0.0</BBB>
	<BBA>4.0.1</BBA>
	<BBB>4.1.0</BBB>
	<BBA>4.1.1</BBA>
	<AAA>3.1.0</AAA>
	<AAB>3.1.1</AAB>
	<AAA>3.2.0</AAA>
	<BBB>4.1.0</BBB>
	<BBA>4.1.1</BBA>
	<BBC>4.1.2</BBC>
</MAIN>

The new Document sould look like this:
======================================

<?xml version="1.0" encoding="UTF-8"?>
<MAIN>
	<MSG>1.0</MSG>
	<ORG>2.0</ORG>
	<Group1>
		<AAA>3.0.0</AAA>
		<AAB>3.0.1</AAB>
		<AAC>3.0.2</AAC>
		<Group2>
			<BBB>4.0.0</BBB>
			<BBA>4.0.1</BBA>
		</Group2>
		<Group2>
			<BBB>4.1.0</BBB>
			<BBA>4.1.1</BBA>
		</Group2>
	</Group1>
	<Group1>
		<AAA>3.1.0</AAA>
		<AAB>3.1.1</AAB>
	</Group1>
	<Group1>
		<AAA>3.2.0</AAA>
		<Group2>
			<BBB>4.1.0</BBB>
			<BBA>4.1.1</BBA>
			<BBC>4.1.2</BBC>
		</Group2>
	</Group1>
</MAIN>

My problem was to set the ENDTAGS. I tried to do it using XPath .... Here
the not working Stylesheet
witch generate a non well formed XML Dokument.

<!--*************************** THIS STYLESEET IS NOT WORKING CORRECT ******************
-->
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
	<xsl:template match="/">
		<MAIN>
			<xsl:for-each select="MAIN/*">
				<xsl:if test="name() = 'AAA'">
					<xsl:call-template name="setEndTagBBBGroup2"/>
					<xsl:call-template name="setEndTagAAAGroup1"/>
					<xsl:call-template name="setBeginTagAAAGroup1"/>
				</xsl:if>
				<xsl:if test="name() = 'BBB'">
					<xsl:call-template name="setEndTagBBBGroup2"/>
					<xsl:call-template name="setBeginTagBBBGroup2"/>
				</xsl:if>
				<xsl:variable name="tag">
					<xsl:value-of select="name()"/>
				</xsl:variable>
				<xsl:element name="{$tag}">
					<xsl:value-of select="."/>
				</xsl:element>
			</xsl:for-each>
			<xsl:call-template name="setEndTagBBBGroup2"/>
			<xsl:call-template name="setEndTagAAAGroup1"/>
		</MAIN>
	</xsl:template>
	
	<xsl:template name="setEndTagAAAGroup1">
		<!-- get prev node in node-set -->
		<xsl:if test="preceding::AAA[1]">
			<xsl:text disable-output-escaping="yes">&lt;/Group1&gt;</xsl:text>
		</xsl:if>
	</xsl:template>
	<xsl:template name="setBeginTagAAAGroup1">
		<xsl:text disable-output-escaping="yes">&lt;Group1&gt;</xsl:text>
	</xsl:template>
	<xsl:template name="setEndTagBBBGroup2">
		<!-- get prev node in node-set -->
		<xsl:if test="preceding::BBB[1]">
			<xsl:text disable-output-escaping="yes">&lt;/Group2&gt;</xsl:text>
		</xsl:if>
	</xsl:template>
	<xsl:template name="setBeginTagBBBGroup2">
		<xsl:text disable-output-escaping="yes">&lt;Group2&gt;</xsl:text>
	</xsl:template>
</xsl:stylesheet>



Has anybody a idea how to do that?
Thanks
