generating and returning xml

[Jeff Brown-2]

I want to create a link in one of my views that will return dynamically
generated xml to the browser.  In my view I have something like this...

<a href="${createLink(action:'xmlmovies')}">get xml</a>

In my controller I want xmlmovies to build up the xml and return it to
the browser.  I think I may want to do something like this...

def xmlmovies = {
  def domBuilder = groovy.xml.DOMBuilder.newInstance()
  def movies = domBuilder.movies() {
    Movie.findAll().each {
      movie(title:it.title)
    }
  }
}

At that point, I am not sure how to render the xml back to the
response.  I expect I may need to call the render() method and set the
contentType attribute to 'text/xml' but I am not sure exactly.

Any help would be appreciated.

Thanks.

render(contentType:'text/xml') {
    movies  {
       for( m in Movie.findAll() ) {
             movie(title:m.title)
         }
    }
}

The above will do it

Cheers

How would I do this if each movie was it's own object and there was a title, year, genre, etc..?

so it would be :

<movies>
    <movie>
        <title>Heat</title>
        <genre>Action</genre>
        <year>1999</year>
    </movie>
    <movie>
        <title>Jaws</title>
        <genre>Suspense</genre>
        <year>1973</year>
    </movie>
</movies>

thanks.

1) Use Automatic XML Marshalling

<a href="http://grails.org/doc/latest/guide/6.%20The%20Web%20Layer.html#6.1.7 XML and JSON Responses">http://grails.org/doc/latest/guide/6.%20The%20Web%20Layer.html#6.1.7 XML and JSON Responses

def movieList = [movie1, movie2]

movieList as XML

<list>

 <movie>

...

</movie>

<movie>

</movie>

</list>

2) User contentType on controller render

http://grails.org/doc/latest/ref/Controllers/render.html

If you really need the root node to have the name <movies>, then you will need to build your own.  If you are returning this from a controller you can use the content type of the render method.

render contentType: "application/xml", {

      movies {

        movieList.each {movieIt ->

          movie {

            title movieIt.title

            genre movieIt.genre

            year movieIt.year

          }

        }

      }

    }

3) Use Groovy's MarkupBuilder

If none of the above work for you:
