xml - Can't get XSL to Display Correctly with XSL Variables and XPATH -
i'm making basic contact list web app 3 pages - contact list page displays contacts in db (stored in xml file), contact view page (that read-only page displays contact information), , new contact page (that allows make new contact or edit information of existing contact).
my issue contact view page. each contact has id, , id passed through url (i.e. contactviewer?id=mk). using id, hoping using simple xsl for-each checks url request (saved in xsl variable) pick contact db display work. unfortunately, after adding "for-each" nothing displays on page , can't figure out it's going wrong.
this xsl page contactview.

<contactdatabase> <contact> <firstname /> <lastname /> <address /> <city /> <state /> <zipcode /> <country /> <email /> <phone /> <mail /> <phonenum /> <emailaddress /> <comment /> <id /> </contact> </contactdatabase>
the correct xpath expression select required contact element contactdatabase/contact[id = $currentid].
rather for-each use apply-templates format contact element given id, , write separate template match contact elements. this.
