html - 清理序列化 DOM 的安全正则表达式？

Question

我正在为 JavaScript 的 .replace 方法寻找几个非常安全的正则表达式模式。输入是一个序列化的 DOM 字符串，我想删除所有 YUI3 classNames 和 YUI3 生成的 id 属性。

var resourceDOMStr = Y.DataType.XML.format( Y.Node.getDOMNode(this.getIframeDOMContainer()).innerHTML );
alert('unsanitized markup:\n\n'+resourceDOMStr );
// Remove YUI-added id's and classes
    // regex to remove ' id="*"'
    // regex to remove entire class attr: ' class="'yui3-*'"'
    // regex to remove className + trailing space: class="'yui3-* 'safeClass"
    // regex to remove className + leading space: class="safeClass' yui3-*'"
resourceDOMStr.replace('', '');
alert('sanitized markup:\n\n'+resourceDOMStr );

是的，我想干净一点，删除整个 id 属性，它的值总是以“yui_3”开头，例如； id="yui_3_3_0_1_1296949124608175"。另外，如果它唯一的类是 YUI3 生成的类名，我想删除整个类属性，否则我只想删除 YUI3 类名和任何前导/尾随空格。生成的类名总是以 'yui3-' 开头，examples;

• class="yui3-dd-shim"
• class="safeClass yui3-dd-shim"
• class="yui3-dd-shim safeClass"

...我不希望“safeClass”被改变，我不希望前导/尾随空格的堆积，因为生成的替换字符串将被多次加载、清理和保存.

非常感谢任何头痛解决者。

希望上面的一切都很好，不要太轻易地把它拆开 - 如下面评论中所述，它的示例 html。

Answer 1

你可以试试这个怪物:

var dirty = 'class="yui3-dd-shim" class="safeClass yui3-dd-shim" class="yui3-dd-shim safeClass"';

var clean = dirty.replace(/class="yui[0-9]-[^\s]+"|\s?yui[0-9]-[^\s"]+\s?|id="yui_[0-9][^"]+"/gi, '');

在您的示例数据上对其进行了测试，似乎可以完成工作。
