人 民 网 版 权 所 有 ，未 经 书 面 授 权 禁 止 使 用
In total 97 105 071 (2.9%) of the URLs and 127 523 211 (27.8%) of the forms in the set contained elements with one of the pattern attributes. So in general, forms are not very common on web pages, and pattern elements are only moderately common in forms. Note that a web page may contain any number of forms and that forms may repeat across URLs. A typical example would be an email registration form in a page footer or a search bar in a header. To avoid a potentially complex discussion about what constitutes a web page (everything across a domain? What about subdomains?), I used the URL as my base unit. So each instance of the same search bar counts.
