How would I list all entries regardless of section or structure?

Question

I'm trying to build and XML site map that sorts all entries by their modification dates with the newly modified first.

{% for entry in craft.entries.find() %} ignores the structures,

{% for entry in craft.entries.section().find() %} returns the same as above,

{% for entry in craft.entries.section('mainPages').find() %} returns the structure as expected.

Looking for a way to include everything in a single, sortable query.

Answer 1

Actually your code should work just fine. But by default only 100 entries are fetched, maybe you need to increase the limit:

{% set entries = craft.entries.section().limit(null) %}

But if you just want to create a Sitemap, try Ben Croker's Sitemap-Plugin (I really like it)

Answer 2

This should output what you want:

{% for entry in craft.entries.order('dateUpdated desc') %}
    {{ entry.title }}
{% endfor %}

Although the easiest way to create an xml sitemap is to use the Sitemap Plugin.

In addition to the $49 plugin mentioned in other answers, there's also a more basic one that is free: https://github.com/xodigital/SimpleSitemap
