Source code in the zkl programming language

student:=RegExp(0'|.*
unicode:=RegExp(0'|.*(&#x[0-9a-fA-F]+;)|);
xml:=File("foo.xml").read();

students:=xml.pump(List,'wrap(line){
   if(student.search(line)){
      s:=student.matched[1];    // ( (match start,len),group text )
      while(unicode.search(s)){ // convert "É" to 0xc9 to UTF-8
	 c:=unicode.matched[1];
	 uc:=c[3,-1].toInt(16).toString(-8);
      	 s=s.replace(c,uc);
      }
      s
   }
   else Void.Skip; // line doesn't contain 
});

students.println();
