However, in the case of HTML's class attribute, the string can be "dirty", in that the underlying string is derived from a the class attribute. Consider: element.className = " class1 \n class2 \t class3 \t \n" In order to get a clean string, the spec needs to define something the following, so whitespace is removed: //Splits the underlying string into a list of tokens function splitUnderlyingString() { var underString = this.toString(); var cleanString = underString.replace(/\s\s+/g, "\u0020").trim(); return cleanString.split("\u0020"); } Implementation already do the above, it seems. But the above is not clear in the spec. 66559 1 zcorpan 2012-04-10 10:59:21 +0000 The spec uses http://dvcs.w3.org/hg/domcore/raw-file/tip/Overview.html#split-a-string-on-spaces 66560 2 w3c 2012-04-10 12:16:12 +0000 (In reply to comment #1) > The spec uses > http://dvcs.w3.org/hg/domcore/raw-file/tip/Overview.html#split-a-string-on-spaces Ah, my bad. Didn't notice the "split" link.
