我如何从java中的字符串中删除阿拉伯标点符号

问题描述 投票：0回答：5

我正在研究一本阿拉伯语词典，我得到了类似的句子
String original = "' ' ' ' : ' '"; 从我的数据库中，但我无法在不删除重音符号和标点符号的情况下处理句子

我尝试使用

import java.text.Normalizer;
import java.text.Normalizer.Form;
import java.util.regex.Pattern;

public static String deAccent(String str) {
    String nfdNormalizedString = Normalizer.normalize(str, Normalizer.Form.NFD); 
    Pattern pattern = Pattern.compile("\\p{InCombiningDiacriticalMarks}+");
    return pattern.matcher(nfdNormalizedString).replaceAll("");
}

但是没用

尝试此代码，它在我的项目中运行良好：

    private String input;
    private final String output;

    /**

     * @param input String
     */
    public ArabicNormalizer(String input){
        this.input=input;
        this.output=normalize();
    }

    /**
     * normalize Method

    private String normalize(){

为什么不选择 Unicode 标点/标记、非空格类别？

不确定您的预期结果，因为它没有发布 - 而且我看不懂阿拉伯语:)，但请尝试以下代码：

String input = "'أَبَنَ فُلانًا: عَابَه ورَمَاه بخَلَّة سَوء.'";
Pattern p = Pattern.compile("[\\p{P}\\p[Mn]");
Matcher m = p.matcher(input);
while (m.find()) {
    System.out.println("found: " + m.group());
}
m.reset();
System.out.println("Replaced: " + m.replaceAll(" "));

输出：

found: '
found: َ
found: َ
found: َ
found: ُ
found: ً
found: :
found: َ
found: َ
found: َ
found: َ
found: َ
found: ّ
found: َ
found: َ
found: .
found: '
Replaced:  أ ب ن  ف لان ا  ع اب ه ور م اه بخ ل  ة س وء

我想这不是您想要的最终结果，但我希望这是您可以使用的。

此外，this 是有关 Unicode 类别的信息金矿。我相信大多数都适用于 Java 

Pattern
。

我发现这样做更好。非常感谢 joop 的提示。

import java.text.Normalizer;
import java.text.Normalizer.Form;

/**
 *
 * @author Ibbtek <http://ibbtek.altervista.org/>
 */
public class ArabicDiacritics {

    private String input;
    private final String output;

    /**
     * ArabicDiacritics constructor
     * @param input String
     */
    public ArabicDiacritics(String input){
        this.input=input;
        this.output=normalize();
    }

    /**
     * normalize Method
     * @return String
     */
    private String normalize(){

        input = Normalizer.normalize(input, Form.NFKD)
                .replaceAll("\\p{M}", "");

        return input;
    }

    /**
     * @return the output
     */
    public String getOutput() {
        return output;
    }

    public static void main(String[] args) {
        String test = "كَلَّا لَا تُطِعْهُ وَاسْجُدْ وَاقْتَرِبْ ۩";
        System.out.println("Before: "+test);
        test=new ArabicDiacritics(test).getOutput();
        System.out.println("After: "+test);
    }
}

就我而言，这个解决方案是有效的。我尝试了很多解决方案，但没有一个能正常工作。

String diacless = Normalizer.normalize(textWithDiacritics, Normalizer.Form.NFKD).replaceAll("\\p{M}", "");
Log.d("diac_remove", "replaced: "+diacless);

您可以使用这个：

String withDiacritics = "طَائِفِيّةٌ";
String withoutDiacritics = withDiacritics.replaceAll("(ّ)?(َ)?(ً)?(ُ)?(ٌ)?(ِ)?(ٍ)?(~)?(ْ)?", "");

输出将类似于：“???”。
