Question

我有一个包含以下值的字符串：

TOTAL DUE-STATEMENT $ 240.05911费用$ 10.00FRANCHISE税$ .172VSALES税$ .53LOCAL-TAX $ .23服务折扣 - $ 50.00PAYMENT - 谢谢 - $ 100.00HBO + STARLET $ 100.00

我需要将此字符串拆分为键/值对。

TOTAL DUE-STATEMENT $240.05
911 Fee $10.00
FRANCHISE TAX $.17
2VSALES TAX $.53
LOCAL-TAX $.23
SERVICE DISCOUNT -$50.00
PAYMENT - THANK YOU -$100.00
HBO+STARLET $100.00

我的字符串值将始终是动态的，描述是动态的，除了911 Fee 我写了一个正则表达式如下。

([911 a-zA-Z |911 a-zA-Z|a-zA-Z |a-zA-Z \\-? a-zA-Z|! ?|+? ]+)(-?\\$[0-9|,]*\\.[0-9][0-9])

我正确获取键/值对，除了描述包含数字，字母和特殊字符。我的输出如下：

TOTAL DUE-STATEMENT $240.05
911 Fee $10.00
FRANCHISE TAX $.17
SALES TAX $.53   ** Which is wrong**(Expected is 2VSALES TAX as key)
LOCAL-TAX $.23
SERVICE DISCOUNT -$50.00
PAYMENT - THANK YOU-  $100.00 "-" is coming as key (Expected is PAYMENT - THANK YOU)
STARLET $100.00 **- Which is wrong** (Expected is HBO+STARLET)

有人可以帮助我在这个正则表达式中改变我需要的东西吗？

Answer 1

示例：http://regexr.com?35dsq

使用此RegEx

/([-]{0,1}\$\d*\.\d\d)/g

找到$后跟任意数字的数字，然后是.，然后是2位。

然后在替换中使用

 \1\n

Answer 2

描述

此正则表达式解决方案假设money列有时具有-前缀，但始终包含$后跟零个或多个数字，一个点和正好2个数字。其余的字符是名称的一部分。

([^$]*?)(-?\$\d*\.\d{2})

enter image description here

每个捕获组1都有名称，捕获组2将具有美元值。

Answer 3

考虑到总有两个小数位

你的正则表达式可以简化为

.+?[$]\d*[.]\d{2}

你需要匹配模式与上面的regex not split

Matcher m =Pattern.compile(regex).matcher(input);
while(m.find())
{
m.group();
}

Answer 4

当您的价格格式已知时，请搜索它，其间的所有内容都是描述：

    String in = "TOTAL DUE-STATEMENT$240.05911 Fee$10.00FRANCHISE TAX$.172VSALES TAX$.53LOCAL-TAX$.23SERVICE DISCOUNT-$50.00PAYMENT - THANK YOU-$100.00HBO+STARLET$100.00";
    Pattern price = Pattern.compile("-?\\$\\d*\\.\\d{2}");
    Matcher matcher = price.matcher(in);
    int offset = 0;
    while (matcher.find(offset)) {
        String description = in.substring(offset, matcher.start());
        String value = matcher.group();
        System.out.println(description + " " + value);
        offset = matcher.end();
    }

Answer 5

class Main {
    public static void main(String[] args) {
        String test = "TOTAL DUE-STATEMENT$240.05911 Fee$10.00FRANCHISE TAX$.172VSALES TAX$.53LOCAL-TAX$.23SERVICE DISCOUNT-$50.00PAYMENT - THANK YOU-$100.00HBO+STARLET$100.00";
        java.util.regex.Pattern p = java.util.regex.Pattern.compile("(?<KEY>.+?(?=-?\\$[\\d,]*\\.\\d{2}))(?<VAL>-?\\$[\\d,]*\\.\\d{2})");
        java.util.regex.Matcher m = p.matcher(test);
        while(m.find()) {
            System.out.println(m.group("KEY") + " : " + m.group("VAL"));
        }
    }
}

你只需要一个非贪婪的KEY匹配。+？然后是一个前瞻性的VALUE，它总是以一个点结束，两个数字为美分。

Answer 6

这应该这样做：

^(.+) (-?\$\d*\.\d\d)$

正则表达式的后半部分与美元金额相匹配，包括可选的 - 符号。第一部分除了分隔空间外，还包括其他所有内容。

Java中的正则表达式需要处理动态字符串值
