Re: AW: [Dynapi-Dev] DynAPI build, Splitting files

Ahh.. but when you're running those If statements through a loop that
creates several hundred layers, there is a HUGE difference in
performance.... and generation of layers in IE should be changed... as there
is a huge performance hit when the createLayer method is called for all
layers at once... if DOM methods are used, for IE specific, then the layers
can be created as they are instanciated, and when they are to actually be
displayed in the browser, simply use DOM methods to move the node into the
visible browser buffer. It would be like an off-screen buffer holding all
code and properties that would be quickly added in 2 method calls.

IE has a built-in XML parser with DOM methods which can be the back-end
buffer, and should be able to transfer node from the XML tree to the browser
DOM tree. All the property setting would be done in the back-end native
code, thus making it faster.

Who knows DOM? (oh... to create an XML object in IE5+, simply
document.writeln('<XML id="XMLObj"></XML> ');  Then to access:
document.all.XMLObj  references the Document object of the XML DOM tree.
