I have something already made ​​but the value I debuelve the title is this
example

index.php?option=com_k2&view=item&id=273:molayoli-arce-y-catena-estan-destruyendo-el-sindicato&Itemid=118

and need only be

index.php? option = com_k2 & view = item & id = 273

as I can do this to change the values ​​of the link?
thank you very much for the help you can provide

I need is to bring me all artuculo pure content and not like now that I put all the template into the div where the article is showing.

I hope you understand

this link brings everything clean, so you do not know where I can format the link to appear so in the titles

index.php?option=com_k2&view=item&id=254&tmpl=component-item
