Java 正则表达式与多行字符串不匹配

Question

我在查找多行字符串时遇到问题： 我在“contractBytes”变量中有这个文本：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Records xmlns="http://www.datapump.cig.com">
<Contract phaseId="4" operation="2">
    <General>
        <ContractCode>8848</ContractCode>

        <CreditPurpose id="20"/>
        <NegativeStatus id="4"/>
        <ApplicationDate>2009-09-08</ApplicationDate>
        <StartDate>2009-09-08</StartDate>
        <ExpectedEndDate>2011-03-31</ExpectedEndDate>
        <Subjects>
            <Subject roleId="1">
                <Entity>
                    <Individual gender="1">

                        </FirstName>
                        <Surname>
<Text language="uk-UA">Первый</Text>
                        </Surname>
                        <FathersName>

                        </FathersName>

    <Type>
        <Credit paymentPeriodId="9" paymentMethodId="6">
            <CreditLimit currency="USD">7800.0</CreditLimit>

                <Record accountingDate="2011-04-20">
                    <CreditUsage id="3"/>
                    <ResidualAmount currency="USD">7800.0</ResidualAmount>
                    <OverdueAmount currency="USD">0.0</OverdueAmount>
                </Record>
            </Records>
        </Credit>
    </Type>
</Contract>

我正在尝试使用正则表达式：

Pattern p = Pattern.compile("(<Contract)(.)*(Contract>)", Pattern.DOTALL);
Matcher m = p.matcher(contractBytes);
for (;m.find();)
{
    if (m.group(1).contains("<ContractCode>" + contractCode + "</ContractCode>"))
    {
        dealXmlMap.put(Long.parseLong(contractCode), m.group(1));
        break;
    }
} 

但是 m.find 总是返回 false。 我应该如何使用此模式从 contractBytes var 中获取文本？

Answer 1

(<Contract)(.*)(Contract>)

试试这个。见演示。(.)*你只是捕获了第一个字符而不是全部。
