One of the solutions to text loss caused by parsing XML using Sax

Recently, I am working on a small project. I found a solution to the problem of using the sax to parse XML-text data parsing is missing. Here, I would like to share with you some suggestions.
The following XML file:

<Summary>
This book is composed of three beautiful love stories that seem to be independent and actually are connected. The hero is a teacher and enjoys a certain kind of sports. They have personally experienced or witnessed a moment approaching death and learned something in life.
This is the first love novel set of the author after "Call for love at the center of the world. In the age of students, I read the complete set of Modern Japanese literature, including Xia Mushu Shi and Da Jiang Jian sanlang. I also read modern European philosophy from Descartes, levenitz to capitalism and Marx. He has created novels since he was 22 years old and 3 years old. "Breath", "the world runs in a place you don't know", and "Don't trust John Ranon" are all his masterpiece.

The problem is as follows:
When parsing a node <DB: attribute name = "author-Intro">, the text is always missing. Later, the program was improved as follows:

}
}
Cause:
When the text data is too long to be parsed to the current node, the text callback function will be called back multiple times. Using stringbuffer to cache the data is a solution.
