Splitting strings from HTML text area causes unexpected results in GOLANG

Splitting strings from HTML text areas can lead to unexpected results in Golang. This is because during the splitting process, special characters or labels may not be processed correctly, resulting in string segmentation errors, which in turn affects subsequent data processing and display. To avoid this from happening, developers need to carefully handle and escape strings to ensure data integrity and correctness. In Golang, you can use related library functions and methods to split and process strings to ensure the normal operation of the program and the output of expected results.
