The syntax hopefully should be easy to follow being that it resembles how you would use javascript with the HTML,XML DOM. It's just a little bit different, why not just make it the same? Were not scripting against a DOM, (a Documents Object Modle) but a DOM, (a Dialect Object Modle) because you may not actually know the syntax of the loaded document or data before it's transcode to a DOM from a DSL. Plus Rebol wont let you too far off the hook in writing code any way you like. Some *op Words and code/data has set types that follow a strict syntax. I think the best way around this is to load as type? string!, reformat and parse as type? block!. Maybe..... These DOM functions should work very close to the HTML DOM functions: getElementsByTagName .getAttribute .setAttribute ....... <start:rant="on" placed="strategically" skip="yes:no;">you don't have to readthis</rant>........................ HTML,XML DOM is built as a tree structure from a document. In order to get or set something you must search the entire tree with each call to a tag. Before returning a single tag it must first build a nodelist of all alike tags before a method (function call) can be used. You actually need a browser, editor or IDE, and code experience with , javascript, html, css, HTML DOM, XML DOM, HTML5, and to move or share across networks, XSL, XSLT, Xpath, XQuery, Ajax, a server, and server-side/backend with access to client-side frontends, security, and administration. WWWOOOOOWWW!. Rebol parse along with block searching is simpler, faster, easier to code, send, or recieve and uses less memory. The Rebol choir membors know how to do all that need-to-know in one language, Rebol!, WWWOOOOWWW!.... The Rebol upjump (advantage) is a serious downfall. To spend the time using others stuff (bloatware) is a big time waister wich leaves Rebol all but alone, by itself and unused cause that bloatware in its domain can do it better when it's supported by more of the standard bloatware stuff. But have you seen how many disparate languages you need to use in a Web full stack process. To get people to use Rebol it has to have modules, FFI, execute C code, plug-ins, GPU'ed, data-based, IOS-Android and media/browser access, embedable, AI, CLOUD-able, all wrapped up with a pretty open source bow. Please. Thats why i believe RED is the right direction for Rebol. But the wrong direction. Because people only want stuff. Either that suff has to do more stuff or be a part of the best known stuff to make them feel better or a part of the best stuff going on at that moment. So i give in. I want Rebol to catch on, not catch up. The Rebol-DOM is a way to load every body's stuff in, parse that stuff up, change stuff, and send that stuff back out and let that other bloatware stuff deal with it. Rebol don't need no stuff. It needs to progressively replace it by hiding the Rebol language and acting like a cloud Service Oriented Architecture (SOA) open source messenger through the internet. Nothing needs to change. This is what Rebol is and does already. Rebol just needs this kind of App to materialize and offer itself up on a subscription base. ....... <start:rant="off" skip="yes:no;">did you read that. jeeze</rant>........................................................ ************************************************************************************************** markup-DOM my-dialect getnodename {"b"[1]}getattribute "color" node-element document.(getnodename{("p")[2]}).style/width: = "block-build"setattributevalue('height)"1000" node-element getattribute "height" setnodename {b[1]} "listview" node-element document.(getnodename{("p")[1]}).style/font-style: = "block-build" setattribute('font-style)"whithouse" setattributevalue('boogies)"green-color" data-node: do to-path [DOM .p .b .i] document.(data-node).style/color: = "purple" setattribute('i-style) "silly" data-node probe return-html-dsl
