在 Javasript 中将打开和关闭标签转换为自关闭标签

Question

I am trying to compare two html files. One file only uses self-close tag if the content is empty. The other one uses a mix of self-close tag and open-close tag. I would like to convert all the open-close tags in the second file to be self-close tags so that the ending tags in the two html files are in the same format. Is there a simple way to convert open and close tag into self-close tag in javascript?

Example:

<td style=""></td> => <td style="" />

Answer 1

Try cheerio xmlMode:

let $ = cheerio.load(`<td style=""></td>`, {xmlMode: true})
console.log($.html())
// <td style=""/>
