Question

我必须处理xsd模式以通过jaxb生成java代码，并且在其中一个序列中有两个具有相同名称的元素。这引起了麻烦，我开始使用bindings.xml来区分两个元素。

我的问题是我无法为此目的找到一个单一的元素，它是针对我想要的元素以及来自另一个compleType的另一个元素。

        <xs:anyAttribute processContents="skip"/> 
    </xs:complexType> 
</xs:schema>

这是我的bindings.xml

<jxb:bindings version="2.0"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<jxb:bindings schemaLocation="FLUTE-FDT-3GPP-2005-Extensions.xsd" node="/xsd:schema">
    <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
        <jxb:bindings node=".//xsd:attribute[@name='value']">
            <jxb:property name="requiredValue"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>
<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']">
        <jxb:bindings multiple="true" node="//xs:element[2]">
            <jxb:property name="delimiter1"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

因此，第一个分隔符元素被正确地重命名为delimiter1，但schemaVersion元素也被重命名为delimiter1！

有关错误的任何建议吗？

按照我的bindings.xml的建议使用@ref后如下所示：

<jxb:bindings version="2.0"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <jxb:bindings schemaLocation="FLUTE-FDT-3GPP-2005-Extensions.xsd" node="/xsd:schema">
        <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
            <jxb:bindings node=".//xsd:attribute[@name='value']">
                <jxb:property name="requiredValue"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
    <jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
        <jxb:bindings node="//xs:complexType[@name='FileType']">
            <jxb:bindings multiple="true" node="//xs:element[@ref='sv:delimiter'][1]">
                <jxb:property name="delimiter1"/>
            </jxb:bindings> 
            <jxb:bindings node="//xs:element[@ref='sv:delimiter'][2]">
                <jxb:property name="delimiter2"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

现在它重命名sv:delimiter（文档中为3）的所有出现，而不是仅重命名FileType complexe类型中的出现。它比以前更好，但我希望能够只在可能的情况下重命名所选元素。

感谢Xstian，这是正在运行的解决方案：

<jxb:bindings version="2.0"
    xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <jxb:bindings schemaLocation="FLUTE-FDT-3GPP-2005-Extensions.xsd" node="/xsd:schema">
        <jxb:bindings node="//xsd:complexType[@name='MBMS-Session-Identity-Expiry-Type']">
            <jxb:bindings node=".//xsd:attribute[@name='value']">
                <jxb:property name="requiredValue"/>
            </jxb:bindings>
        </jxb:bindings>
    </jxb:bindings>
    <jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
            <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='sv:delimiter'][1]">
                <jxb:property name="delimiter1"/>
            </jxb:bindings> 
            <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='sv:delimiter'][2]">
                <jxb:property name="delimiter2"/>
            </jxb:bindings> 
    </jxb:bindings>
</jxb:bindings>

Answer 1

尝试使用例如

<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']">
        <jxb:bindings node="//xs:element[@ref='mbms2012:Alternate-Content-Location-1']">
            <jxb:property name="delimiter1"/>
        </jxb:bindings>
    </jxb:bindings>
</jxb:bindings>

或

<jxb:bindings schemaLocation="mbms-flute-release11.xsd" node="/xs:schema">
    <jxb:bindings node="//xs:complexType[@name='FileType']//xs:element[@ref='mbms2012:Alternate-Content-Location-1']">
          <jxb:property name="delimiter1"/>
    </jxb:bindings>
</jxb:bindings>
