 Since this is becoming a FAQ (how to get structure out of a flat document), I thought I'd post my general levitating-a-flat-structure stylesheet. Note: its design supports only regular structures (that is, flat files whose nesting is "correct" although only implicit); if you need a more general-purpose solution, one could be based on the same principles (the key declarations would have to be modified). Getting the "formatting" (that is, the transformation of element types) along with the conversion (the levitation) is not hard, only a matter of adapting and supplementing these templates. I hope it helps -- Wendell INPUT FILE: <levels> <h1>Header 1</h1> <stuff>Content under 1</stuff> <h2>header 1.1</h2> <stuff>Content under 1.1</stuff> <stuff>More content under 1.1</stuff> <h2>header 1.2</h2> <stuff>Content under 1.2</stuff> <h2>header 1.3</h2> <stuff>Content under 1.3</stuff> <h3>header 1.3.1</h3> <stuff>Content under 1.3.1</stuff> <h4>header 1.3.1.1</h4> <stuff>Content under 1.3.1.1</stuff> <h5>header 1.3.1.1.1</h5> <stuff>Content under 1.3.1.1.1</stuff> <h1>Header 2</h1> <stuff>Content under 2</stuff> <h2>header 2.1</h2> <stuff>Content under 2.1 </stuff> <h2>header 2.2</h2> <stuff>Content under 2.2</stuff> <h3>header 2.2.1</h3> <stuff>Content under 2.2.1</stuff> <h2>header 2.3</h2> <stuff>Content under 2.3</stuff> </levels> STYLESHEET:
