html - 获取 HTML 元素中使用的类和 ID 的列表

Question

<分区>

Answer 1

据我所知，Netbeans 不支持此功能。我提供了一个 java 类文件，您可以运行它来获取此信息。

1. 在 C 目录中创建一个名为 html 的文件夹。将所有 html/jsp 文件放在 html 目录中。

2. 运行这个java类文件

   import java.io.BufferedReader;
   import java.io.IOException;
   import java.nio.charset.Charset;
   import java.nio.file.DirectoryStream;
   import java.nio.file.Files;
   import java.nio.file.Path;
   import java.nio.file.Paths;
   import java.util.ArrayList;
   import java.util.List;
   import java.util.regex.Matcher;
   import java.util.regex.Pattern;
