Subject: RE: [xsl] alternating bg colour in nested data From: "Andrew Welch" <andrew@xxxxxxxxxxxxxxxxxxxxxxx> Date: Wed, 16 Jan 2002 12:24:55 -0000 |
(please excuse multiple questions, but Ive split them up to make it easier to read :) Also, I would like to output a '.' to indicate how deeply nested an element is. For example, a group3 item would be output as '. . . data' At the moment, Im trying to do this by passing as a parameter the number of dots to either the even or the odd template. This is fine as I can work out the number of dots based on the group name. But if the group name isnt known, is there a way count how 'deep' a node is from another node? For example: <node1> <node2/> <node2/> <startNode> <node3/> <node3/> <node4> <node5> <endNode/> </node5> </node4> </node3> </startNode> </node1> Here I would like the output to be: ....endNode (four dots then endnode, as endnode is four deep from startnode) Is there a piece of code that can do this, using only the structure of the XML file and a known startNode?

I have a suggestion for that as well. >Also, >occasionally two adjacent rows share the same colour (where group changes >and last elem pos was even) You'll have to keep track of the running count of all rows generated. Now I don't know what you are doing in each row, but the example below shows how I keep track of the running row count in a variable that is passed. Note also how I was able to reuse the same template rather than making numerous "groupX" templates ... I am assuming the structure is as regular as you imply it is. If there are no children of the given name, it isn't an error, so asking for all possible children at each level will only give you the children that are at that level. I hope this helps. .............................
