How to disable parsing code in script tags using JavaScript DOMParser?

I have the following text file with JavaScript tags:

<script>
...
</script>
<script>
...
</script>
<script>
...
</script>

when I parse it like so:

const parser = new DOMParser();
const xmlDoc = parser.parseFromString(`<root>${data}</root>`, "text/xml");
const tags = xmlDoc.getElementsByTagName("script");

I get an error because there are < and > symbols in JS program code, like

for (let i = 0; i < tags.length; i++) {

I don't want to replace < > with &lt; &gt; because those are also present inside strings in the code.

Is it possible to disable parsing code inside script tags?

Solution

  • For parsing HTML, we use the mime type text/html

    const htmlDoc = parser.parseFromString(data, "text/html");
const tags = htmlDoc.getElementsByTagName("script");
