Re: [basex-talk] Templating

      Thanks a lot ! it solved it.
I had tried to change the view file to xquery, but i dont’t know why, i didn’t test with a variable declaration at first.

It works with individual variable declaration (`view1.xq`), but I can’t get back the map itself (in `view2.xq`). Is it a consistent behavior ? Am I missing some Xquery’subtleties here ?

```xquery

xquery version "3.0" ;

module namespace test = 'test.test';
import module namespace xquery = "http://basex.org/modules/xquery";

declare function test:render($template as xs:string, $map as map(*)){
   xquery:invoke($template, $map)
};

declare %restxq:path('/test')
        %restxq:GET
function test:test(){
  let $map := map{ "greeting" : "hello", 
                   "who": "world"}
  return test:render('view1.xq', $map )
};

declare %restxq:path('/test2')
        %restxq:GET
function test:test2(){
  let $map := map{ "greeting" : "hello", 
                   "who": "world"}
  return test:render('view2.xq', $map)
};

```

view1.xq
```xquery

xquery version "3.0" ;
declare variable $greeting external;
declare variable $who external;

<div>{$greeting, $who}</div>

```

view2.xq
```xquery

xquery version "3.0" ;
declare variable $map as map(*) external;

<div>{map:get($map, 'greeting')}</div>

```

Hi,
I’ve been trying to use the templating proposed by Andy Bunce here 
http://cubeb.blogspot.fr/2012/11/xquery-templating-engines-and-txq.html
https://mailman.uni-konstanz.de/pipermail/basex-talk/2012-November/004209.ht...
I’ve tried with txq module in different ways. But, I can’t figure out why I couldn’t reproduce it. 
Here is the simpler exemple I’ve tried :
In the webapp folder an xml file, named `view1.xml` wich contains :
```xml
<div>{map:get($map, 'greeting')}</div>
```
In webapp a restxq file with :
```xquery
module namespace test = 'test.test';
import module namespace xquery = "http://basex.org/modules/xquery";
declare function test:render($template as xs:string, $map as map(*)){
  xquery:invoke($template,$map)
};
declare %restxq:path('/test')
       %restxq:GET
function test:test(){
 let $map := map{ "greeting" : "hello", 
                  "who": "world"}
 return test:render('view1.xml', $map )
};
```
Arrêté à /Users/emmanuelchateau/Documents/basex/webapp/view1.xq, 1/15:
[XPST0008] Undefined variable $map.
I’m running BaseX version 7.9
Is there still anybody with this kind of templating running ?
Thanks a lot for your help.
Emmanuel
