Re: : RE: suppressing default template rules

That was very good explanation. I am still working on
the fundementals. Just to check the oder in which the
nodes are processed i made the following changes to my
xml,xsl documents. 

<?xml version="1.0" ?>
<custdet>custdettag
	<employee>emptag</employee>
	<firstname>first</firstname>
	<lastname>last</lastname>
</custdet>

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

<xsl:template match="*">
	<br/>
	------
	<xsl:value-of select="generate-id()" />
	<xsl:value-of select="name()" />
	------
	<br/>
	<xsl:apply-templates/>
</xsl:template>

<xsl:template match="text()">
	<br/>
	---text---
	<xsl:value-of select="generate-id()" />
	<xsl:value-of select="name()" />
	------
	<xsl:value-of select="."/>
	---/text---
	<br/>
</xsl:template>

</xsl:stylesheet>


The expected output (as per the following node
structure)_

/ (root node)
 +- custdet
 |   +- 'custdettag'
    +- employee
    |   +- 'emptag'
    +- firstname
    |   +- 'first'
    +- lastname
        +- 'last'
was,

root 
------ N400001custdet ------ 
---text--- N400002 ------ custdettag ---/text--- 
------ N400003employee ------ 
---text--- N400004 ------ emptag ---/text--- 
------ N400005firstname ------ 
---text--- N400006 ------ first ---/text--- 
------ N400007lastname ------ 
---text--- N400008 ------ last ---/text--- 

But what i am getting now is

root 
------ N400001custdet ------ 
---text--- N400002 ------ custdettag ---/text--- 
------ N400003employee ------ 
---text--- N400004 ------ emptag ---/text--- 
---text--- N400005 ------ ---/text--- 
------ N400006firstname ------ 
---text--- N400007 ------ first ---/text--- 
---text--- N400008 ------ ---/text--- 
------ N400009lastname ------ 
---text--- N40000A ------ last ---/text--- 
---text--- N40000B ------ ---/text--- 

if i apply <xsl:strip-space elements="*"/> i am
getting the expected output.

from which node does the ---text--- N400005 ------
---/text--- ,---text--- N400008 ------ ---/text---
,etc.. getting printed.

Thanks in advance
