The jsoup safelist sanitizer works by parsing the info HTML (in a protected, sand-boxed climate), and afterward emphasizing through the parse tree and just permitting known-safe labels and characteristics (and qualities) through into the cleaned yield. It doesn’t utilize customary articulations, which are improper for this undertaking.

jsoup Examples

Now let’s see the example of jsoup maven as follows.

First, we need to create the maven project in eclipse as shown in the following screenshot as follows.

Now add above mentioned dependencies in the chúng tôi file as follows.

In the above code, we added jsoup dependencies as shown.

Now create a package inside the demo1 project and inside the package we need to create the class as shown in the following screenshot as follows.

Now inside the class file write the following code as follows.

Explanation

By using the above code, we try to find out the all hyperlinks of chúng tôi Here we first import the required packages and library as shown. After we write the code for HTTP protocol and how we can get the all hyperlinks for google as shown.
