删除ascii文本格式

Posted 2021-02-25

This is useful if you are loading html-text via XML and want to remove additional line-breaks, newlines, formfeeds and tabs. It just leaves the clean html.

public static function removeAsciiFormatting(str:String):String {
	if (str != null) {
		var pattern:RegExp = /(	|
|f|
)*/gm; // remove tabs, newlines, formfeeds and returns
		return str.replace(pattern, '');
	} else {
	        return null;
	}
}
