如何从 HTML 中删除多个空白字符？

我想删除来自用户端的额外空白，但我无法预测 HTML 的格式。

例如：

<p> It's interesting that you would try cfsetting, since nothing in it's
documentation would indicate that it would do what you are asking.
Unless of course you were mis-reading what "enableCFoutputOnly" is
supposed to do.


</p>

请指导我如何从 HTML 中删除多个空白字符。

您可以使用正则表达式将任何多个空白字符替换为单个空格，方法是循环结果，直到不再出现多个空白：

lastTry = "<p>   lots of space    </p>";
nextTry = rereplace(lastTry,"\s\s", " ", "all");
while(nextTry != lastTry) {
  lastTry = nextTry;
  nextTry = REReplace(lastTry,"\s\s", " ", "all");
}

在 CF10 中测试工作。
