I'm making a website with eZPublish 3.7 and I want to build a page which sums up all published news. So I want to display only the first 200 characters of each news. I've seen the shorten template operator (http://ez.no/doc/ez_publish/technical_manual/3_6/reference/template_operators/strings/shorten) but I 'm actually not able to retrieve the content of the news without any (xml or html) tags.Is there a way to get an XML Block as a plain text or a better way to retrieve just the beginning of it ?
Thanks for help.

You can use $node.data_map.your_xml_block.content.output.output_text|strip_tags() to recieve a plain text version.
But you'll have to create a custom template operator named strip_tags first:http://ez.no/products/ez_publish_cms/documentation/development/extensions/template_operator
The function could look like this (including all the required stuff described in the above documentation page):
... case 'strip_tags': { $operatorValue = $this->strip_tags($operatorValue, $namedParameters['allowable_tags']); } break; ... function strip_tags($str, $allowable_tags) { return strip_tags($str, $allowable_tags); }

The strip_tags function is already defined i php. All you need to do follow the instructions from the above-mentioned link, and just add the line: PHPOperatorList[reverse]=strip_tagsto template.ini. Remember to clear to cache.

I thought that this method works only for PHP functions with one parameter as stated in the docs: http://ez.no/products/ez_publish_cms/documentation/development/kernel/custom_template_operators(Notes/Limitations)
Does this work for PHP functions with more than one parameters yet or does it work because the second paramter of strip_tags is optional?
Anyway, if it does, Mads way is surely the easier one.

The method only works with functions that take one parameter, but as you mention the second parameter of strip_tags is optional. This must be the reason, why it works in this case. I have succesfully used the simple method.

Good to know, this will save me some time in the future.Thank you for the info.
Now it's Damien's turn to say if this is what he was looking for. *g*

thanks for answers !
I use the "PHPOperatorList" method as I need to remove all tag.Juste one precision if somebody needs to use this method, you have to write
$your_text|strip_tags()
and not
strip_tags($your_text)
Script start
Module start 'content'
Module end 'content'
Script end
