Hi Peter,
Thanks,
This will work fine for me only when I have @destination as
//every[..]/event[...]
As u guessed this will not be always same or say never same again !
I am working on implementing dyn:evaluate function !
http://www.xmleverywhere.com/tips/xslt.htm 

but I am unable to work with it !

Any idea about how to use this function or any other technique that would be
best suited for this situation?

Regards
Yaswanth Ravella

Just not possible dynamically.

It seems you expect $dest to be substituted in the following xpath
expression. This is not happening.
The select you do in setting the variable $dest gives you a sequence of
attribute values.
There is no substitution when you use the variable.

Assuming the @destination always contains '//every[..]/event[...]'
(which will most probably not be the case) you need something like this
to get the name:

Keep the dest selection as you have and then do following (of course
only one solution, which is based on an assumption too):

	<xsl:variable name="every"
select="substring-before(substring-after($dest,'/every['),']')"/>
<xsl:variable name="event"
select="substring-before(substring-after($dest,'/event['),']')"/>
	<xsl:value-of select="//every[$every]/event[$event]/@name"/>

As you can see, you may need a lot of analyzing of the @destination when
my assumption is not correct.

Regards,
Peter

In your fisrt xsl <xsl:variable name="dest"
select="//every[1]/event[1]"/>  will get a *node* /root/every[1]/event[1], 
which do has a @name attribute. Then $dest/@name will get this attribute
value.

But in your second xsl  <xsl:variable name="dest"
select="//pattern[1]/connection[1]/@destination"/>   will get the *string*
"//every[1]/event[1]"
which is the value of @destination. $dest is not a node, it's a string and
you can't do $dest/@name, it doesn't make sens.

As said Christoph you need to evaluate the string, and there is
unfortunately no xslt 1.0 native way to do this !
You need a extension eval function depending on your xslt processor. 
If you use saxon for example, something like this should go <xsl:value-of
select="saxon:eval($dest)/@name"/>.
With msxml you can do your own eval function in jscript, have a look at
http://www.xmleverywhere.com/tips/xslt.htm
You can also use EXSLT extensions I think.

Hope this help, 

Cheers, 

Matthieu.
