Subject: [xsl] slicing an XML document From: Saverio Perugini <sperugin@xxxxxxxxxxxxxxxx> Date: Tue, 15 Oct 2002 13:15:53 -0400 (EDT) |
Hello, Is it possible to slice an XML tree into levels? In other words, parameterize a stylesheet by level number and return all tags or name()'s corresponding to that level. Consider the following XML: <db> <small> <olives> <thin/> </olives> <onions> <thin/> <thick/> </onions> </small> <med> <onions> <pan/> <thin/> </onions> <peppers> <crispy/> <thick/> </peppers> </med> <large> <peppers> <pan/> <thin/> </peppers> <ham> <crispy/> <thick/> </ham> </large> </db> Imagine that the leaves correspond to a pizza order and the levels correspond to size, topping, and crust, in that order. If I'd like a list of all possible sizes then I want to slice the tree at the first level; and desire the following output. small, med, large If I'd like a list of all possible toppings, then I want to slice the tree at the second level; and desire the following output. olives, onions, peppers, ham And lastly, if I'd like a list of all possible crusts, then I want to slice the tree at the third level; and desire the following output. thin, thick, pan, crispy Is there a quick and dirty way to slice an XML document? Thank You and Best Regards, S. Perugini XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
