Ran HTML through local server so that parse a text file that is written in XML format. Inside the XMLHttpRequest function, I am able to print the node of the xmlDoc variable I want. But then outside the XMLHttpRequest function, it basically forgets what is stored in the xmlDoc variable.
Why, am I not able to bring the parsed XML xmlDoc variable output out of the XMLHttpRequest function?
HTML
<!DOCTYPE html>
<html>
<body>
<p id="demo"></p>
</body>
<script>
var xmlDoc = new DOMParser();
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
parser = new DOMParser();
xmlDoc = parser.parseFromString(this.responseText,"text/xml");
console.log(xmlDoc.getElementsByTagName("title")[0].childNodes[0].nodeValue)
}
};
xhttp.open("GET", "project_content.txt", true);
xhttp.send();
console.log(xmlDoc.getElementsByTagName("title")[0].childNodes[0].nodeValue)
</script>
</html>
TXT File
