please could someone outline how I would go about exporting the content / users in ez and migrating it to a different CMS?

for drupal i have found the following:
http://drupal.org/node/5289

is there no easier way / export function?

Cheerio,
Nic

Hi Nicholas,

that example works only for the old eZ publish 2.x
for that version, I wrote a simpler PHP script to migrate all the contents to Drupal, that I can copy here.

But I have to say that, after the migration, I migrated again the contents to eZ publish (3.x version); eZ is definitely more powerful and complete than Drupal, there's no comparison.

/**

 * this is a script to export data
 * from  eZ publish 2 into Drupal's postgres database
 *
 *
 * create a new database (testdata), containing ez publish's and drupal's tables
 NOTE: if your eZ publish database is set up with the character encoding (LATIN9),
you need to migrate the contents to the UTF-8/Unicode encoding. More information can be found in PostgreSQL documentation.

 * CREATE DATABASE testdata ENCODING='UTF8';

 * pg_dump --encoding=UTF8 ezpublish > ezpublish.sql
 * pg_dump drupal > drupal.sql
 * psql testdata < drupal.sql
 * psql testdata < ezpublish.sql
 *
 * practice command to extract ez publish's table list (tables to remove from the live database):
   psql -U drupaluser -W  -c "SELECT table_name FROM information_schema.tables WHERE table_schema = 'public'" drupal_database > tables.txt

 * run these queries:
 * drop table indexes_ez_drupal; // needed only if you made other migration tests before

personnaly I would recommend using rss feeds to export your data.

There is a very good exemple on how to export your data using rss feeds on this page:
http://pwet.fr/blog/des_fils_rss_sur_mesure_dans_ez_publish

unfortunatly this is in french, but basically, all you need to do is create an overide for your pagelayout, and create an rss view. In which you will put the following code:

<?xml version="1.0" encoding="iso-8859-1"?>
<rss version="2.0">
<channel>
<language>fr-FR</language>
{$module_result.content}
</channel>
</rss>

You will then simply need to create overrides to display the various content:
design/<mon_design>/templates/node/view/rss_full.tpl

You will then need an import function to import your data in drupal.

this simple function will read the url you whish. All you will need to do the is get the info in the xml using the xml parser you would like and import the data in your database. This way you could

function getFlux($flux)
{
$handle = fopen($flux, "rb");
$contents = '';
while (!feof($handle)) {
$contents .= fread($handle, 8192);
}
fclose($handle);
return($contents);
}
