Hi Martin,
	Sorry "reset of all the tags", is a spelling mistake. Correct one is,
all other tags such as [RollNum,EmpID, ...etc] should copy as it is
into some other file.
My finall out will be:
<Employees>
                        :
                        :
        <Employ>
                <EmpName>..</EmpName>   //Only this statement has
changed. Except no change
                <RollNum>..</RollNum>
                <EmpID>..</EmpID>
                        :
                        :
        </Employ>
	<Employ>... </Employ>
	<Employ>... </Employ>
		:
                        	:
<Dept>....</ Dept >
<Dept>....</ Dept >
	:
		:
:
<Employees>

      Good snippet you have given but still i need your help to
resolve my problem,
Here are my 3 queries:
1)	in my case I have to handle like this so can you please suggest
some more good snippet in this way.

<xsl:apply-templates select="Employee"/>
//Here I have transfer only single Employee node and I want to iterate
all the nodes in single employee and check a perticular node and do
some operations. Like below.

<xsl:template match=" Employee ">
		<xsl:choose>
			<xsl:when test="name">
				<xsl:element name="EmpName">
					<xsl:value-of select="name"/>
				</xsl:element>
			</xsl:when>
		</xsl:choose>
		Copy rest of the nodes here.
</xsl:template>

1)	<xsl:apply-templates select=" "/> :
a.	if am using "apply-templates" statement then my output was like
below (this is like my final structure with no data). I don't know why
this happened in my prog.
<Employ> </Employ>
<Dept> </ Dept >
:
:
: etc.
2)	I have read about <xsl:copy> is not using then result will be in
different way. Is this in my case because I am not using <xsl:copy> ?

3)	i have got some value like this:
<xsl:template match="instance">
		<!--	<xsl:copy-of select="instance"/> -->
		<xsl:element name ="instance">
			<xsl:value-of select="."/>
		</xsl:element>
</xsl:template>
 so I want to change my statements like this
If(<xsl:value-of select="."/> != "")
{
	//Create Element "instance node "
		<xsl:element name ="instance">
			<xsl:value-of select="."/>
		</xsl:element>

}
becase if <xsl:value-of select="."/> value is null even i am creating
a node with null string so i have to avoid this case.
So how can I go about in this case. If I stored "select="."" value in
a variable and I can check it. But in my prog I had many statement
like this. for all statements I would create variables ? I hope its
not good way.
