Parse data from html response

Question

I'm sending a GET request to a WMS service through angular's HttpClient. The response what I get is a html in string. How can I parse data from this string?

The response looks like this:

<html>
<head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></head>
<body>
<p>Temperature 16.6 °C</p>
<p>Temperature 18.2 °C</p>
</body></html>

I need to get the values inside the paragraph tags. I found solutions only to display data through innerHtml directive, but this is not my case.

EDIT:

I found one possible solution through DOMParser:

const parser = new DOMParser();
const doc = parser.parseFromString(myHtmlStringResponse, "text/html");
const values = [];

const p = doc.getElementsByTagName("p");

for (const item of Array.from(p)) {
     values.push(item.textContent);
}

DOMParser is the simple and robust answer to this question, whereas stripping HTML is an arbitrary answer which may only work in specific circumstances — AFOC

Strip all the html from the response with this regEx:

data.replace(/<(?:.|\n)*?>/gm, '');

where data is your response string

You will get this:

Temperature 16.6 °C
Temperature 18.2 °C

You can use parse through using tag name.

var pele = document.getElementsByTagName('p');

for(var i=0;i< pele.length;i++) {
  console.log(pele[i].innerHTML)
}

But make sure if you are using jquery then put this code snippet under ready function.
