I am looking to write a Java app which queries multiple URLs (defined by a list of URIs) for their HTML source and returns the contents of a specific element with a defined id on each page.

As an example, lets say one started with a list of a list of blog post URLs such as…

…now, if a sample page looks like the following…

<html>
<body>
    <div class="content">
        <h2 id="post_title">Post Title</h2>
        <p class="post_paragraph">Here is the content of my post.</p>
    </div>
</body>
</html>

How can I grab the contents of the “post_title” id for each of my URLs, and print it to the console with the classic System.out.print(String s)?

Thanks for all input.

    First you resolve the URL using Java’s connection API

    http://download.oracle.com/javase/6/docs/api/java/net/URLConnection.html

    Then you will need to parse the HTML

    And finally you will need to walk the parsed document structure (that will depend on the parser you choose) to find an element with the given id.
