You'll find a description of an XSLT 2.0 stylesheet that does this (and some other things besides) at http://www.idealliance.org/proceedings/xml04/papers/111/mhk-paper.html Michael Kay http://www.saxonica.com/ > -----Original Message----- > From: Rowan Sylvester-Bradley [mailto:rowan@xxxxxxxxxxxxxxxxxxxxx] > Sent: 12 October 2008 18:44 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] Creating Hierarchy > > Hi, > > I have an XML file that represents a tree of data elements, > similar to a directory tree. The structure of the file has > every node in the tree represented by a <node> element, all > children of the root, with the hierarchy defined by a <level> > element within each node. So the <node> with <level> = 0 is > the root of the tree, its children have <level> = 1, their > children have <level> = 2 etc. Here's an example: > > <mytree> > <node> > <name>Root of my tree</name> > <level>0</level> > </node> > <node> > <name>Child of root</name> > <level>1</level> > </node> > <node> > <name>Another child of root</name> > <level>1</level> > </node> > <node> > <name>Grandchild of root</name> > <level>2</level> > </node> > <node> > <name>Yet another child of root</name> > <level>1</level> > </node> > </mytree> > > I want to transform this into a hierarchical file like this: > > <newnode> > <name>Root of my tree</name> > <newnode> > <name>Child of root</name> > </newnode> > <newnode> > <name>Another child of root</name> > <newnode> > <name>Grandchild of root</name> > </newnode> > </newnode> > <newnode> > <name>Yet another child of root</name> > </newnode> > </newnode> > > How do I write a stylesheet to do this? > > Thanks - Rowan
