</MyDB>

Now the issue is i need to insert the data from source file to destination file by changing the names of the elements and tags with reference to destination file... ie, for example <Fname> in the source file must be changed to <FirstName> in destination file

Can any one help me on this?

Answer 1

You probably want to start off by reading about the XSLT Identity Transform . This would just copy all elements as-is

<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

In your case though, it looks like only the fathersname element is unchanging. You then need to write templates to match the elements you do want to change, and create new elements in their place. For example, to 'rename' the Studentdatabase to MyDB you would do the following:

<xsl:template match="Studentdatabase">
   <MyDB>
     <xsl:apply-templates select="@*|node()"/>
   </MyDB>
</xsl:template>

And to change Student into tableName you would do the following:

<xsl:template match="Student">
   <tableName>
     <xsl:apply-templates select="@*|node()"/>
   </tableName>
</xsl:template>

If you repeat this for all the elements you want to rename, you should be able to get your expected output.
