Subject: * getter.xsl added
X-Git-Tag: v0_1_3~86
X-Git-Url: http://matita.cs.unibo.it/gitweb/?a=commitdiff_plain;h=0b1e5fb100fe57fb53f98038570b1fae191d331d;p=helm.git

* getter.xsl added
  In this stylesheet there is a simple function to make the URL
  of an XML file given its URI. (The URL is used to ask the getter
  to retrieve the file)
* every other stylesheet (but ricerca.xsl that is unused and
  links_library.xsl) has been changed to use the new function
  instead of computing the URL cutting&pasting the same code
  again and again.
