It's easy to see that a lot of redundant information is missing. Because there is no need to have an end tag (closing tag) that matches the start tag (opening tag), the number of bytes required to transfer the same information is greatly reduced. Founder Corockford called it the "XML W

In this case, we suddenly realized that the basic data classes were obfuscated in the original obfuscation, resulting in the original fields becoming the corresponding 'a, B, C, S ..... and data

In today's big data era, data is money. With the transition to an application-based domain, data shows exponential growth. However, 80% of the data is unstructured, so it requires a program and method to extract useful information and convert it into an understandable and available structured form.
