Update XSLT to provide grouping and sorting

I have an input XML and default XSL files that transforms into HTML. (The actual file will be shown to the winner only.) XML will have some elements with parent-child relationship (2 levels). E.g. to simplify <item **path**="abc" /> and <item **path**="xyz" **parent**="abc" **order**="1" isChild="true"/> Currently all the items are rendered unordered. What I need is: Group parent-child items together and render them as · parent o child 1 o child 2 o ... ordering will be done based on child's attribute "**order**". The position of parent element in the output should be the earliest occurrence of parent-childs. So if the parent exists and is 10th place, the child is 5th place, then the whole parent-child set should be on 5th place. If there is NO parent element for the child, one must be rendered anyways based on **path** attribute. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
