how translate the title from the component within the Installfile (.xml).

<?xml version="1.0" encoding="utf-8"?>
<install type="component" version="1.5.0">
   <name>COMPONENT NAME</name>

When the language it's british it's must show "Component Title". When the language it's the spanish language it's must show "Nombre del Componente", like a title of my very own componet within the Extensions Manager.

Thank's

The component details are saved within the database. Doing the work how you have carried out won't work. I do not think this really is supported. An elementOritem must have 1 title. You should not have different names for the product/component. Microsoft don't call Home windows another title in The spanish language, German, etc - you want to do exactly the same.

With Joomla 1.6 you are able to translate it. See docs here.

For Joomla 1.5, you cannot.
