Jsoup Study notes 9:jsoup parse saz file, read the HTM file into the string, extract the data from the string into the CSV file

This note will be the operation of the previous note to make some improvements, no longer the HTM file in the Saz file parsing out, but not to read the data directly into the string, the basic idea is as follows:

1. Customize a class that reads content from a text file to a string: Parses an HTM document in a saz file and reads the contents of the file into a string

2. Customize the class that uses Jsoup to parse the HTM string: Parse the incoming HTM string with Jsoup and write the results to a CSV file

3, when parsing, specify a good file path, directly call the above two tool classes can be

The sample code is as follows:
