Efficiently adapting html content for Vue localization

I've been utilizing the v-html tag to display HTML in my Vue pages. However, I came across a string that was a complete HTML file with content like this:

<html xmlns="https://www.w3.org/1999/xhtml">
<head>
....
<style>
</style>
</head>

<body style="....">
</body>

</html>

The issue is that when I use v-html on a div, the code starts affecting the entire page and adds its styling to the whole page instead of just that specific div.

I attempted adding "scope" to the style tags, but it didn't work. Perhaps because there's also an inline style tag on the body?

I'm searching for a solution to ensure that the HTML only affects the div it's placed on and not the entire page.

If you want to effectively manage the HTML content added using v-html, one approach could be to refine the content by extracting only the <body> tag. This can be achieved through parsing techniques, such as utilizing a library like DomParser instead of relying on regular expressions. Here is an example implementation with DomParser:

const DomParser = require("dom-parser");
const parser = new DomParser();

export default {
  // ...
  computed: {
    html() {
      const rawHtml = "<html><body><div>test</div></body></html>"; // Ensure that this data is fetched from your server
      const dom = parser.parseFromString(rawHtml);
      return dom.getElementsByTagName("body")[0].innerHTML;
    }
  }
}

It's important to note that this solution may be oversimplified, especially in scenarios where the HTML lacks a <body> tag.

It is crucial to exercise caution when incorporating external HTML content using the v-html attribute, as this could potentially expose your website to security vulnerabilities (refer to the Vue documentation for more information).

Should you decide to trust the source of the HTML, another consideration is how to integrate it without impacting the integrity of your own site. One solution to this is utilizing the <iframe> element - while not entirely risk-free, with proper precautions and understanding, it can isolate the external HTML content from affecting your site.
