TYPO3 Core

What version of TYPO3 and what version of what browser?

IE8
TYPO3 4.3.2

i could isolate the problem at least to the line "140" in remove-format.js where it's about "keep tags, strip attributes"

ok, i found a solution but it's a very interesting one.
these are the original lines:
// keep tags, strip attributes
var regMS3 = new RegExp(" style=\"[^>\"]*\"", "gi");
var regMS4 = new RegExp(" (class|align)=(([^>\s\"]+)|(\"[^>\"]*\"))", "gi");

these are the fixed ones:
// keep tags, strip attributes
var regMS3 = new RegExp("style=\"[^>\"]*\"", "gi");
var regMS4 = new RegExp("(class|align)=(([^>\s\"]+)|(\"[^>\"]*\"))", "gi");

i just removed a whitespace and that's it. but how will this affect some other stuff?

Please try

var regMS4 = new RegExp(" (class|align)=\"[^>\"]*\"", "gi");

without changing the other line.

Shouldn't that be:

var regMS4 = new RegExp("( |\t|\n)(class|v?align)=\"[^>\"]*\"", "gi");

An HTML-tag can be spread out over several lines, and if an attribute can start at the beginning that line, hence a newline (\r, \n) instead of a space (or in general, tabs for that matter).

Removing the leading whitespace all together would work in about 99% of cases, but in HTML5 custom attributes are allowed AFAIK, so let's take it into account.

<script type="text/javascript">
var re_space = new RegExp(" (class|v?align)=\"[^>\"]*\"", "gi");
var re_whitespace = new RegExp("( |\t|\n)(class|v?align)=\"[^>\"]*\"", "gi");

alert('<input\nclass="bar"/>'.replace(re_space,''));
alert('<input class="bar"/>'.replace(re_space,''));
alert('<input class="bar"/>'.replace(re_space,''));

alert('<input\nclass="bar"/>'.replace(re_whitespace,''));
alert('<input class="bar"/>'.replace(re_whitespace,''));
alert('<input class="bar"/>'.replace(re_whitespace,''));
</script>

@Stanislas: that works too, thanks.

I wonder why i get different results in Firefox 3.6 and IE8... any ideas?

@Dimitri : In what way are the results different? Do you mean the results of the paste or the results of the remove format operation? Certainly, if you paste content from MS Word, all browsers will do it differently.

@Rik: yes, but newlines are replaced by spaces a few instruction before. Not tabs, though. The attached patch will fix this.
