I think the ideal newline normalization for parsing (even attribute values) into the DOM is: line1\rline2 -> line1\nline2 line1\nline2 -> line1\nline2 line1\r\nline2 -> line1\nline2 line1\n\rline3 -> line1\n\nline3 line1 line2 -> line1\nline2 line1 line2 -> line1\nline2 line1 line2 -> line1\nline2 line1 line3 -> line1\n\nline3 line1
line2 -> line1\nline2 line1
line2 -> line1\nline2 line1
line2 -> line1\nline2 line1

line3 -> line1\n\nline3 Firefox and Safari pretty much do this except for the \r\n situation. A raw \r\n pair will be normalized to \n, but if \r\n is made up of entities, it gets normalized to \n\n. So, for stuff besides attribute values, the Firefox and Safari normalization generally looks the same as above except for: line1 line2 -> line1\n\nline2 line1
line2 -> line1\n\nline2 Opera generally doesn't do any normalization except for textareas where it normalizes newlines to \r\n to be form data friendly I guess. IE generally normalizes like Firefox and Safari, but normalizes to \r instead. For attributes values, Firefox, Safari, Opera and IE generally accept what's there and don't normalize anything. (exceptions being certain elements like the param element for Opera , IE and I think certain situations with applets and params in Firefox.) So, based on all that, so far, I'd say that newlines in attributes (raw or entity-based) should not be normalized (only because doing so would be too big of a change?). For the rest of the markup, Firefox and Safari's way of normalization (just talking storage, not rendering) (minus the entity-based \r\n quirk) would probably be ideal. At any rate, if all browsers normalized the same, that would be something. -- Michael
