如何从XPath的子级值节点获取父级文本值？

Question

How can I get the UUID from the addressinformation (in this case 999123 ) where the address name is "BILL_TO" (if any) with Java XPath?

Here is my XML:

    <Company>
        <Name>My Company</Name>
        <LastName>Smith</LastName>
        <FirstName>Jim</FirstName>
        <street>123 Main Street</street>
        <AddressInformation>
                <UUID>543233<UUID>
            <Address>
                <UUID>223223</UUID>
                <AddressID>
                    <AddressName>Default</AddressName>
                </AddressID>
            </Address>
        </AddressInformation>
        <AddressInformation>
                <UUID>999123<UUID>
            <Address>
                <UUID>443211</UUID>
                <AddressID>
                    <AddressName>BILL_TO</AddressName>
                </AddressID>
            </Address>
        </AddressInformation>
        <city>Mytown</city>
        <state>NY</state>
        <zip>11234</zip>
</Company>

ok first off your XML wasn't well formed so I fixed this it for you

 <Company>
    <Name>My Company</Name>
    <LastName>Smith</LastName>
    <FirstName>Jim</FirstName>
    <street>123 Main Street</street>
    <AddressInformation>
            <UUID>543233</UUID>
        <Address>
            <UUID>223223</UUID>
            <AddressID>
                <AddressName>Default</AddressName>
            </AddressID>
        </Address>
    </AddressInformation>
    <AddressInformation>
            <UUID>999123</UUID>
        <Address>
            <UUID>443211</UUID>
            <AddressID>
                <AddressName>BILL_TO</AddressName>
            </AddressID>
        </Address>
    </AddressInformation>
    <city>Mytown</city>
    <state>NY</state>
    <zip>11234</zip>
</Company>

then this is the xpath which should do the trick for you:

//Company/AddressInformation[Address/AddressID/AddressName='BILL_TO']/UUID
