[bug]: dom nest parsing issues

[jsonz1993]

Hello, I find a few parsing issues in version: 0.16.4

input:

<button >
  Hello <input type="file" ng-hide="true" />PostHtml
</button>

const output = posthtml().process(input, { sync: true })

output:

<button>
  Hello </button><input type="file" ng-hide="true">PostHtml

expect

<button >
  Hello <input type="file" ng-hide="true" />PostHtml
</button>

@jsonz1993 Hi, nice catch.

Hello, I looked at the code and found that it was a problem with htmlparser2, and then went to raise issues with htmlparser2. Later, I found out that in fact, you only need to pass in a parameter when calling posthtml to avoid this problem.

posthtml()
    .process(htmlStr, {
      xmlMode: true,
    });
