XSL transformation of xml files to HTML

we have a collection of XML files (see q/*.xml) all adhering to the [login to view URL] schema, see the output of: ls -1 q/*.xml | xargs xmllint --schema [login to view URL] --noout we currently generate a HTML view of the same data (see w/*.html), but that is ugly and does not use CSS for formatting we need an XSL transformation to convert the xmls to HTML with: - a horizontally-split two-frame view - left pane: drillable, clickable treeview of the models and submodels - right pane tabbed (similar to what we have today) view of strings, integers and quantities for the currently selected object in the treeview - prev/next/up navigation buttons requirements: - keep a decentralized structure of small HTML files rather than a single HTML file (an exception could be the treeview pane) - the resulting HTML should validate as XHTML 1.0 Strict on [login to view URL] - compatible with Webkit, IE8+ and Firefox 20+ - use CSS for formatting for the convenience of generating the treeview by transformation of a single XML file rather than picking up information spread around different XML files, we will provide a [login to view URL] file according to your specification if you plan to include any third-party javascript libraries, please tell us when you place the bid so that we can review it from the point of view of the license, dependencies and technology
