Xpath 匹配表达式给出两个字符串值

Question

我有提取以下值的要求。

<cidx:ReferenceInformation ReferenceType="DeliveryNoteNumber">
                    <cidx:DocumentReference>
                        <cidx:DocumentIdentifier>5004330471</cidx:DocumentIdentifier>
                    </cidx:DocumentReference>
                </cidx:ReferenceInformation>

我正在使用下面的 Xpath 表达式并获得 2 个值匹配。

表达式

/*[local-name()='Envelope']/*[local-name()='Body']/*[local-name()='ShipNotice']/*[local-name()='ShipNoticeBody']/*[local-name()='ShipNoticeProperties']/*[local-name()='ReferenceInformation']/*[local-name()='DocumentReference']/*[local-name()='DocumentIdentifier']/text()

输出

 <?xml version="1.0" encoding="UTF-8"?>
<result>
5004330471
0803692106
</result>

我测试过在线工具中的Xpath [http://www.xpathtester.com/xpath][1]

下面是INPUT XML

<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP:Header/>
<SOAP:Body>
    <cidx:ShipNotice xmlns:cidx="urn:cidx:names:specification:ces:schema:all:4:0" Version="4.0">

            </cidx:ShipNoticeProperties>
        </cidx:ShipNoticeBody>
    </cidx:ShipNotice>
</SOAP:Body>
</SOAP:Envelope>

谁能告诉我如何只获得这个值？

<cidx:DocumentIdentifier>5004330471</cidx:DocumentIdentifier>

Answer 1

看来您需要测试 cidx:ReferenceInformation 元素中的 ReferenceType 属性：

/*[local-name()='Envelope']/*[local-name()='Body']/*[local-name()='ShipNotice']/*[local-name()='ShipNoticeBody']/*[local-name()='ShipNoticeProperties']/*[local-name()='ReferenceInformation' and @ReferenceType='DeliveryNoteNumber']/*[local-name()='DocumentReference']/*[local-name()='DocumentIdentifier']

注意：如果您可以声明名称空间并在路径中使用前缀，则可以清理很多 xpath。

如果您使用的是 XPath 2.0，您也可以使用 * 作为前缀来清理它...

/*:Envelope/*:Body/*:ShipNotice/*:ShipNoticeBody/*:ShipNoticeProperties/*:ReferenceInformation[@ReferenceType='DeliveryNoteNumber']/*:DocumentReference/*:DocumentIdentifier
