Learning XML/XSL/Xpath/Xquery...

[Cowboy Bob]

"but even then, if you've already got the whole DOM tree loaded then XPath is a lot more convenient" - that's true but the whole point is to avoid having to do that if poss. (load into an xmldocument). a recent problem was having to extract a repeating series of nodes from a large document which contained many documents and stick them all (the subsets) into oracle. was faster using a reader.

In that case it would be faster using a SAX parser.

Problem with extensions is that it breaks the whole point of XSL - abstract yourself from particular language, if you hack with C# in it then you might as well as stick to C#.

Using string functions for simple matching in XmlReader might be faster indeed, but it might be that they use Xpath internally for that anyway - generally speaking I'd say if there are performance constraints on any code that deals with XML/XSL then in this case either custom parsing should be used or XML/XSL should be dropped altogether.

what mix c# and html........hmmmm

They call it ASPX I think...

ah the tulipe with '<%' directive actually in the aspx file rather than the code behind class file.
C'mon atw keep the abstraction

You must be one of the Mixed Verbose Code design pattern fans

I don't use ASPX - I have my own simple scripting language with interpreter written in C#, it is very fast and does not depend on IIS - it depends on my own mini webserver written also in C#

I have found this site invaluable over the years: http://www.dpawson.co.uk/xsl/index.html

XSL/T is quite tricky to get into if your head is wired for "normal" programming activities but there are some pretty good explanations and real world examples here as well as some more advanced techniques.

Hope this helps.

I found this book invaluable to me to learn the basics of XSLT. I found her writing style really easy to follow,
