Question

是否可以获取HTML项目中使用的所有类/ ID的列表？

我正在处理的项目有18个HTML页面（JSP公平），我想知道每个页面上使用了哪些类/ ID。

例如：<div class="div-class" id="div-id">包含类"div-class"和标识"div-id"。我不想手动搜索每个页面并记下我找到的所有类/ ID。

有没有可以为我做这个的工具？

我使用NetBeans 8.0.2作为IDE，因此如果可以使用NetBeans执行此操作，那就太棒了！

据我所知，Netbeans不支持这种功能。我正在提供一个java类文件，您可以运行该文件以获取此信息。

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。

运行此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;

public class HtmlIdsAndClasses {

    public static void main(String[] args) {

        String path = "C:\\html";

        scanFiles(path);
    }

    private static void scanFiles(String pathLocation) {

        try (DirectoryStream<Path> directoryStream = Files.newDirectoryStream(Paths.get(pathLocation))) {
            for (Path path : directoryStream) {

                HtmlPageInfo pageInfo = new HtmlPageInfo();
                List<String> classList = new ArrayList<String>();
                List<String> idList = new ArrayList<String>();
                pageInfo.setPageName(path.getFileName().toString());
                pageInfo.setClassList(classList);
                pageInfo.setIdList(idList);
                getAllIds(path, pageInfo);
                getAllClasses(path, pageInfo);
                System.out.println(pageInfo);
            }
        } catch (IOException ex) {}
    }

    private static void getAllClasses(Path file, HtmlPageInfo pageInfo) {

        Pattern classPattern = Pattern.compile("class=\"([-A-Za-z_ ]*)\"");
        Charset charset = Charset.forName("UTF8");
        BufferedReader reader = null;
        try {

            reader = Files.newBufferedReader(file, charset);
            String line = null;
            while ((line = reader.readLine()) != null) {

                Matcher classMatcher = classPattern.matcher(line);
                while(classMatcher.find()) {
                    String classGroup = classMatcher.group(1);
                    for(String cls : classGroup.split(" ")) {
                        pageInfo.getClassList().add(cls);
                    }
                }
            }
        } 
        catch (IOException x) {
            System.err.format("IOException: %s%n", x);
        }
        finally {

            if(reader != null) {
                try {
                    reader.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    private static void getAllIds(Path file, HtmlPageInfo pageInfo) {

        Pattern idPattern = Pattern.compile("id=\"([-A-Za-z_]*)\"");
        Charset charset = Charset.forName("UTF8");
        BufferedReader reader = null;
        try {

            reader = Files.newBufferedReader(file, charset);
            String line = null;
            while ((line = reader.readLine()) != null) {

                Matcher idMatcher = idPattern.matcher(line);
                while(idMatcher.find()) {
                    String id = idMatcher.group(1);
                    pageInfo.getIdList().add(id);
                }
            }
        } 
        catch (IOException x) {
            System.err.format("IOException: %s%n", x);
        }
        finally {

            if(reader != null) {
                try {
                    reader.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

class HtmlPageInfo {

    private String pageName;
    private List<String> idList;
    private List<String> classList;
    public String getPageName() {
        return pageName;
    }
    public void setPageName(String pageName) {
        this.pageName = pageName;
    }
    public List<String> getIdList() {
        return idList;
    }
    public void setIdList(List<String> idList) {
        this.idList = idList;
    }
    public List<String> getClassList() {
        return classList;
    }
    public void setClassList(List<String> classList) {
        this.classList = classList;
    }

    @Override
    public String toString() {

        StringBuilder sb = new StringBuilder();
        sb.append("[Page - ");
        sb.append(pageName);
        sb.append("]");
        sb.append("\n\t[IDs - ");
        sb.append("(" + idList.size() + ")]\n\t\t");
        for(String id : idList) {
            sb.append(id + ",");
        }
        sb.append("\n\t[Classes ");
        sb.append("(" + classList.size() + ")]\n\t\t");
        for(String cls : classList) {
            sb.append(cls + ",");
        }
        sb.append("]\n\n");

        return sb.toString();
    }
}

您将在控制台中获得输出，如下图所示。
