假设我正在使用HtmlCleaner ( v2.18 ) 清理一些 html，并且我想将属性invalidAttributeNamePrefix（请参阅Cleaner 参数部分）设置为某个值，即： data- .
这样my-custom-attr="my-value"，HTML 中的属性将被转换为data-my-custom-attr="my-value".
我怎样才能做到这一点？我找不到Java 用法的任何示例。
您可以将这段代码作为参考：
HtmlCleaner cleaner = new HtmlCleaner();
CleanerProperties properties = cleaner.getProperties();
properties.setOmitComments(true);
// properties.setInvalidAttributeNamePrefix("data-"); there is no such method
// html is a declared variable which contains some html content
TagNode rootTagNode = cleaner.clean(html);
XmlSerializer xmlSerializer = new PrettyXmlSerializer(properties);
String cleanedHtml = xmlSerializer.getAsString(rootTagNode);
