Hello,
I'm new to XSL and need some help with ordering of output.
I'm trying to describe a navigational menu and then render it
according to which item is selected.
The attached XML and XSL source files are quite close
to what I want except for the ordering. The output I'm aiming
for is:
??? TOP
??? MENU
??? tit1
??? tit2
??? Pp tit23
??? Pp Pp tit231
??? Pp Pp SELECTEDtit232
??? tit3??????????? <-----***
??? tit4
but the output I'm getting is:
??? TOP
??? MENU
??? tit1
??? tit3??????????? <-----***
??? tit2
??? Pp tit23
??? Pp Pp tit231
??? Pp Pp SELECTEDtit232
??? tit4
(note the out-of-order 'tit3' title). Can someone please explain
why this is happening, and what I need to do to fix it!.....
Also, on the same theme, Ideally I would like to say in one xml
document: 'this page relates to the menu item x', and separately
in an XSL stylesheet I would like to describe the menu and
process it according to the menu that was selected in the xml source.
I haven't tried this yet, but I'm presuming I can do something
like compare the node string-value in the xml with the menu items
and determine which matches and continue from there. If anyone
would like to offer an example of how to do this I would be grateful! :)
