Example

It is a simple example of using the isXMLDoc() method. In this example, we are using the isXMLDoc() method to determine whether the passed values are in the XML document or itself an XML document. Here, we are passing different values as an argument.

Here, there are two variables, one is storing the XML, and another one is storing the simple string. We are also using the $.parseXML() and $.parseHTML() methods to parse the variables into XML and HTML files. Then we will pass the variables to the isXMLDoc() method to check the results.
