JAXB解组并嵌入了XSD [英] JAXB unmarshall and embedded XSD

问题描述

我有一个嵌入XSD的XML，所以它类似于：

I have an XML who embed the XSD, so it's something like :

<?xml version="1.0" standalone="yes"?>
<NewDataSet>
  <xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
    <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
      <xs:complexType>
        <xs:choice minOccurs="0" maxOccurs="unbounded">
          <xs:element name="Table">
            <xs:complexType>
              <xs:sequence>
                <xs:element name="elem1" type="xs:string" minOccurs="0" />
                <xs:element name="elem2" type="xs:string" minOccurs="0" />
                <xs:element name="elem3" type="xs:string" minOccurs="0" />
                <xs:element name="elem4" type="xs:string" minOccurs="0" />
                <xs:element name="elem5" type="xs:string" minOccurs="0" />
              </xs:sequence>
            </xs:complexType>
          </xs:element>
        </xs:choice>
      </xs:complexType>
    </xs:element>
  </xs:schema>
  <Table>
    <elem1>random1</elem1>
    <elem2/>
    <elem3>random3</elem3>
    <elem4>random4</elem4>
    <elem5>random5</elem5>
  </Table>
</NewDataSet>

我目前正在使用嵌入式XSD的克隆作为Schema：

I'm currently using the a clone of the embedded XSD as Schema :

<xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
  <xs:complexType>
    <xs:choice minOccurs="0" maxOccurs="unbounded">
      <xs:element name="Table">
        <xs:complexType>
          <xs:sequence>
            <xs:element name="elem1" type="xs:string" minOccurs="0" />
            <xs:element name="elem2" type="xs:string" minOccurs="0" />
            <xs:element name="elem3" type="xs:string" minOccurs="0" />
            <xs:element name="elem4" type="xs:string" minOccurs="0" />
            <xs:element name="elem5" type="xs:string" minOccurs="0" />
          </xs:sequence>
        </xs:complexType>
      </xs:element>
    </xs:choice>
  </xs:complexType>
</xs:element>

但问题是，当我想解组条目XML时，我收到以下错误消息：

But the problem is that, when i want to unmarshal an entry XML I get the following error message :

意外元素（uri： http://www.w3.org/2001/XMLSchema ，local：schema）。预期的元素是< {} Table>

unexpected element (uri:"http://www.w3.org/2001/XMLSchema", local:"schema"). Expected elements are <{}Table>

我试图在我的XSD上添加标签但是没有成功，仍然会收到错误，因为命名空间（我猜？）。

任何帮助和解释都会非常感激。

I tried to add the tag on my XSD but without success, still get an error because of the namespace (i guess ?).
Any help and explanations would be really appreciate.

推荐答案

您可以在 XMLStreamReader 上利用StAX StreamFilter ，以便不将与XML模式对应的元素报告为事件。然后你可以使用JAXB从 XMLStreamReader 解组。

You can leverage a StAX StreamFilter on an XMLStreamReader so that the elements corresponding to the XML schema are not reported as events. Then you can unmarshal from the XMLStreamReader with JAXB.

• JAXB过滤解析

• JAXB filtered parsing
