如何在 java 中使用分隔符从 xml 文件中读取键和值

Question

我想使用 java 读取以下 xml <LINE> 标记。你能帮忙吗？提前谢谢。

<?xml version="1.0" encoding="UTF-8" ?> 
<LINE>002:OR,004:0001,002:01,002:01,007:SCEM_02,000:,007:590,000,002:KG,002:PC;/</LINE> 

Answer 1

import java.util.regex.*;
public String extractLine(String xmlSource) {
    Pattern p = Pattern.compile("<LINE>(.*?)</LINE>");
    Matcher m = p.matcher(xmlSource);
    boolean found = m.find();
    if (!found)
        return null;
    return m.group(1);
}

特定情况的解决方案是：

String str = "<LINE>002:OR,004:0001,002:01,002:01,007:SCEM_02,000:,007:590,000,002:KG,002:PC;/</LINE> ";
str = str.substring((str.indexOf(">")+1),str.lastIndexOf("<"));
System.out.println(str);
