如何parse/split一个字符串？

Question

这是我从数据库返回的字符串，

"N,591;F\"Vendor Number\",86;F\"Vendor Name\",143;F\"Claim Number\",82;"

并存储在字符串列中，

我想提取 'Vendor Number'、'Vendor Name' 和 'Claim Number'..我该怎么做？谢谢...

Answer 1

应该这样做：

String string = "N,591;F\"Vendor Number\",86;F\"Vendor Name\",143;F\"Claim Number\",82;";
String[] s = string.split("\"");
System.out.println(s[1]);
System.out.println(s[3]);
System.out.println(s[5]);

输出：

Vendor Number
Vendor Name
Claim Number

如果列标签的数量未知，请选择每个备用索引。

Answer 2

打包测试；

进口java.util.ArrayList；导入 java.util.StringTokenizer;

public class StringSplitTest {

public static void main(String[] args) {

    StringTokenizer st = new StringTokenizer("N,591;F\"Vendor Number\",86;F\"Vendor Name\",143;F\"Claim Number\",82;",";");
    while (st.hasMoreElements()) {
        StringTokenizer notRequired = new StringTokenizer((String) st.nextElement());
        StringTokenizer st1 = new StringTokenizer((String) st.nextElement(),",");
        StringTokenizer st2 = new StringTokenizer((String) st.nextElement(),",");
        StringTokenizer st3 = new StringTokenizer((String) st.nextElement(),",");
        System.out.println(st1.nextElement()+ " = " + st1.nextElement());
        System.out.println(st2.nextElement()+ " = " + st2.nextElement());
        System.out.println(st3.nextElement()+ " = " + st3.nextElement());

}

} }
