So, in this section, we are going to solve how to extract content from tag in Java with different approaches and logic. Also, we will create Java programs for the same.

Problem Statement

In this problem, we have given a string of text (tag-based language), and our goal is to parse the text and retrieve the content. We retrieve the data enclosed within a sequence of the well-organized tags meeting the following criterion:

  1. The start and end tag names should be the same. For example, HTML code <h1>Test</h3> is considered as invalid code because it starts with h1 tag and ends with h2 tag.
  2. The content between nested tags is considered invalid. However, the tags can be nested.
  3. Any number of characters can be contained by tags.


Suppose, we have given the following text wrapped inside tags.
