I wanted to generate a sitemap for my radiant powered site and used this  
code:

- 

Unfortunately it doesn’t work since r:children\_each is non recursive.  
Anyone  
has an idea on how to make it recursive?

Giovanni -

I would first create a global tag, using any one of the methods  
previously  
discussed on the mailing list. The tag would be defined like so:

tag “if\_children” do |tag|  
tag.expand if tag.locals.page.has\_children?  
end

Then I would create a snippet that is similar to yours called “sitemap”:

\<r:children:each\>

- 

In the page that I want the sitemap I would do this (the find tag is  
optional, depending on where you want the sitemap to start):  
\<r:find url="/\>

Good luck!

Thanks, that kind of recursion what was I looking for. Actually you  
don’t  
even need the if\_children tag since \<r:children:each\> won’t execute if  
there  
are no children.

This is the final code I used.

In the sitemap page:

The sitemapper snippet:

\<r:children:each\>  
\<r:unless\_content part=“no-map”\>

-   
\<r:link /\>  

  
\<r:snippet name=“sitemapper” /\>  

  
  
\</r:unless\_content\>  
\</r:children:each\>

Thanks for posting this!

I’ve updated the wiki’s HowTo section with a ‘Recipies’ section, as  
discussed on list last week, and made this the first one! 🙂

[http://dev.radiantcms.org/radiant/wiki/HowToMakeASiteMap](http://dev.radiantcms.org/radiant/wiki/HowToMakeASiteMap)

The only significant change is that I made use of

\<r:children:each by=“title” order=“asc”\>

as otherwise the sitemap is ordered by Radiant’s page id numbers so  
the first page in the sitelist is the first page created

Well it’s a honor to be the first there 🙂

I was sure I was using by=“title” 🙂
