VERY COOL!
I've got some code that you might be interested in... It's pretty basic, but it implements a browser-based transformation DOM cache which assigns an ID to a particular DOM that has been transformed, storing the result in an array cache. It then checks the array cache before running a transformation to see if its already been run, and if yes, returns the DOM from the cache instead. I wrote this one morning who knows how long ago, and never came back to it (the name of the file alone to make that an easy point to notice ;), so without a doubt it can be improved upon, but if its something that you find useful, you can access it here > http://www.xsltblog.com/xslclient-test.js The pertinent pieces of code are, function loadXMLFeed(feedID){
var inMemory = false;
var xmlFeedLength = xmlFeeds.length;
var i;
for (i = 0; i< xmlFeedLength; i++){
if (xmlFeeds[i][0] == feedID){
inMemory = true;
return xmlFeeds[i][1];
}
}
if (!inMemory){
for (i = 0; i< xmlURLList.length; i++){
if (xmlURLList[i][0] == feedID){
var tempDoc = loadAtomFeed(xmlURLList[i][1]);
xmlFeeds[xmlFeedLength] = new Array(feedID, tempDoc);
return tempDoc;
}
}
}
return false;
};And, function checkTransformCache(target, dom, style, xmlfeed){ var inCache = false; var i; if (transformCache.length){
for (i = 0; i< transformCache.length; i++){
if (transformCache[i][0] == xmlfeed){
target.innerHTML = transformCache[i][1];
inCache = true;
}
}
} if (!inCache){
setDOMSource(dom);
setStylesheet(style);
setFeedID(xmlfeed);
Transform();
}}; Playing with your code now... Thanks! :D Robert Koberg wrote: M. David Peterson wrote:Hey Robert,
