Wikipedia:Java库删除Wikipedia文本标记删除

分两步进行:

1. 让一些现有的工具将MediaWiki标记转换成纯HTML;
2. 将纯HTML转换为文本。

以下演示:

import net.java.textilej.parser.MarkupParser;
import net.java.textilej.parser.builder.HtmlDocumentBuilder;
import net.java.textilej.parser.markup.mediawiki.MediaWikiDialect;
import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.parser.ParserDelegator;
import java.io.StringReader;
import java.io.StringWriter;

public class Test {

    public static void main(String[] args) throws Exception {

        String markup = "This is ''italic'' and '''that''' is bold. \n"+
                "=Header 1=\n"+
                "a list: \n* item A \n* item B \n* item C";

        StringWriter writer = new StringWriter();

        HtmlDocumentBuilder builder = new HtmlDocumentBuilder(writer);
        builder.setEmitAsDocument(false);

        MarkupParser parser = new MarkupParser(new MediaWikiDialect());
        parser.setBuilder(builder);
        parser.parse(markup);

        final String html = writer.toString();
        final StringBuilder cleaned = new StringBuilder();

        HTMLEditorKit.ParserCallback callback = new HTMLEditorKit.ParserCallback() {
                public void handleText(char[] data, int pos) {
                    cleaned.append(new String(data)).append(' ');
                }
        };
        new ParserDelegator().parse(new StringReader(html), callback, false);

        System.out.println(markup);
        System.out.println("---------------------------");
        System.out.println(html);
        System.out.println("---------------------------");
        System.out.println(cleaned);
    }
}

This is ''italic'' and '''that''' is bold. 
=Header 1=
a list: 
* item A 
* item B 
* item C
---------------------------
<p>This is <i>italic</i> and <b>that</b> is bold. </p><h1 id="Header1">Header 1</h1><p>a list: </p><ul><li>item A </li><li>item B </li><li>item C</li></ul>
---------------------------
This is  italic  and  that  is bold. Header 1 a list: item A item B item C 

在哪里下载要导入的java包?

如果你需要纯文本,你应该使用WikiClean库 https://github.com/lintool/wikiclean .

1) 当文本不是XML格式时,应该添加执行此处理所需的XML标记。假设您之前正在处理XML文件,而现在您有了没有XML结构的内容,那么您只需像下面的代码那样添加xmlStartTag和xmlEndTag,它就会处理它。

String xmlStartTag = "<text xml:space=\"preserve\">";
String xmlEndTag = "</text>";
String articleWithXml = xmlStartTag + article.getText() + xmlEndTag;
WikiClean cleaner = new WikiClean.Builder().build();
String plainWikiText = cleaner.clean(articleWithXml);

WikiClean cleaner = new WikiClean.Builder().build();
String plainWikiText = cleaner.clean(XMLFileContents);

Mylyn WikiText 可以将各种Wiki语法转换为HTML和其他格式。它还支持MediaWiki语法,这也是Wikipedia使用的语法。虽然mylynwikitext主要是一个Eclipse插件,但它也是 available as standalone library .

试试这个 Mediawiki text to plain text 接近。您可能需要改进PlainTextConverter类以满足您的需要。 结合 example for converting Wikipedia texts to HTML

你可以用 Jwiki 获取维基百科数据示例:

Jwiki jwiki = new Jwiki("elon musk");
System.out.println("Title :"+jwiki.getDisplayTitle()); //get title
System.out.println("Text : "+jwiki.getExtractText());  //get summary text
System.out.println("Image : "+jwiki.getImageURL());    //get image URL
