2.java中使用　

 

package com;

import org.apache.commons.io.FileUtils;

import java.io.File;
import java.io.IOException;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class test {
    public static void main(String[] args) throws IOException {
        Pattern pattern = Pattern.compile("ods_ogg_erp_cd[\\w-]{1,1000}");
        String path = "F:\\python\\codes\\pythonLearn\\mappingScript_erp_cd_e5_26.xml";
        File file = new File(path);
        List stringList = FileUtils.readLines(file, "utf-8");
        for (String line : stringList) {
            Matcher matcher = pattern.matcher(line);
            if (matcher.find())
                System.out.println(matcher.group(0));
        }
    }
}
