I don't like this mockup. This should be part of our standard Office import feature, and as such it should provide the simplest interface possible for basic users, without cluttering the UI with regexps and "Leave empty if..." messages. Instead, this should be split into 2 dialogs, one with the file input field, and checkboxes for "Clean the document styles to better match the content of the wiki" and "Split the document into several wiki pages". If the second checkbox is selected, then when pressing Next the second dialog appears, and the user can select the rest of the information. > Descriptions of various fields are as follows: > > * Document - The office document to be uploaded (and imported) > > * Style filtering - Whether to filter office styles or not > > * Heading level to split - If the user wishes to split the imported document > into multiple wiki pages, he has to select the heading level (h1, h2, h3... > h6) to be used when splitting the document.

This is the best option if we want to consider large documents and memory consumption. This, however, will make the splitter harder to integrate in the current rendering engine. -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
