Re: [xsl] getting the last value of a nodeset

["Prasad Akella" <avlnprasad@xxxxxx>]

hi

I am sorry i do not want to evaluate the xpath expression. i would like to have the last segment of the xpath statement as i would be using that same string to name a control in my xhtml page. thus a control in an xhtml page and the node in an xml document would be matched and i can put the value thus entered from the user browser into the respective tag. thus i have to get the last string which represents a node in an xml document and name an xhtml control with the same. i hope i am clear

with regards,
Prasad
