[ckan-dev] How to access source XML document from harvested dataset?

Thu Dec 18 09:20:26 UTC 2014

Hi Bruce,

I don't think that's a good idea to have different data on the frontend and
the CKAN backend. This means that a user that uses the CKAN API to access
this data would not get the data, and in general it's so much easier to
display and style data in the "CKAN way" than having to hack around it.

But if you really really really want to do that, you have to write a custom
template helper function (
https://ckan.readthedocs.org/en/1485-rtd-theme/theming/templates.html#custom-template-helper-functions)
where you load in the XML and parse it to then have the information
available to display in the template.
