When you want to determine the order of articles into an sequence returned by an XQuery query, you can use the > operators:
- X > Y: is true if Y is before X;
For example, suppose you have the following sequence of strings:
Shark, Daisy, Hunter, Lego, Helly
Use this query:
let $xml:=doc(?file:///C://Data_Local//xml//AirWings.xml?)for $a in $xml/company/aircrafts for $b in $xml/company/aircrafts return(if($a/type<
The query returns:
Shark[--Shark, Shark--]Daisy, Shark--]Hunter, Shark--]Lego,Shark--]Helly, Daisy[--Shark, Daisy[--Daisy, Daisy--]Hunter,Daisy--]Lego, Daisy--]Helly, Hunter[--Shark, Hunter[--Daisy,Hunter[--Hunter, Hunter--]Lego, Hunter--]Helly, Lego[--Shark,Lego[--Daisy, Lego[--Hunter, Lego[--Lego, Lego--]Helly ,Helly[--Shark, Helly[--Daisy, Helly[--Hunter, Helly[--Lego,Helly[--Helly
