What kind of solution are you looking for?

Here is an XQuery solution:

let $doc := doc('input.xml')
let $fr := $doc/tag1/tag2[tag3 = 'fr']
let $nl := $doc/tag1/tag2[tag3 = 'nl']
return concat(($fr/tag4, $fr/tag5)[1], ' ', ($nl/tag4, $nl/tag5)[1])

You can use XQuery with Saxon 9 from <URL:http://saxon.sourceforge.net/> 
or with Altova XML tools from <URL:http://www.altova.com/altovaxml.html>
