XJC似乎完全忽略了我的XML Schema元素上的mixed="true"
,从而不允许我提取文本内容。从下面的示例XML中,我需要能够提取“Title Text”。如果没有识别到mixed="true"
,则不会创建任何访问器,也不会从XML取消编组:
<?xml version="1.0" encoding="UTF-8"?>
<title xmlns="urn:hl7-org:v3" integrityCheck="true">Title Text</title>
这是一个完整但经过简化的模式示例,用于演示问题:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xs:schema targetNamespace="urn:hl7-org:v3"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="urn:hl7-org:v3"
xmlns:mif="urn:hl7-org:v3/mif"
elementFormDefault="qualified">
<xs:complexType name="ST" mixed="true">
<xs:complexContent>
<xs:restriction base="ED">
<xs:sequence>
<xs:element name="reference" type="xs:string" minOccurs="0" maxOccurs="0"/>
<xs:element name="thumbnail" type="xs:string" minOccurs="0" maxOccurs="0"/>
</xs:sequence>
<xs:attribute name="compression" type="xs:string" use="prohibited"/>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
<xs:complexType name="ED" mixed="true">
<xs:complexContent>
<xs:extension base="BIN">
<xs:sequence>
<xs:element name="reference" type="xs:string" minOccurs="0" maxOccurs="1" />
<xs:element name="thumbnail" minOccurs="0" maxOccurs="1" type="xs:string" />
</xs:sequence>
<xs:attribute name="compression" type="xs:string" use="optional" />
<xs:attribute name="integrityCheck" type="xs:string" use="optional" />
<xs:attribute name="integrityCheckAlgorithm" type="xs:string" use="optional" default="SHA-1" />
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:complexType name="BIN" abstract="true" mixed="true">
<xs:complexContent>
<xs:extension base="ANY">
<xs:attribute name="representation" use="optional" type="xs:string" default="TXT" />
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:complexType name="ANY" abstract="true">
<xs:attribute name="nullFlavor" type="xs:string" use="optional" />
</xs:complexType>
<xs:element name="title" type="ST" />
</xs:schema>
请注意,上述示例中我使用了 mixed="true"。尽管如此,生成的模式片段中并不包含对它的引用,生成的类也没有使用 XmlMixed 注解,也没有值或内容访问器。/**

为什么XJC / JAXB完全忽略了我的混合内容字段?我尝试过JAXB 2.1和JAXB 2.2,但生成的代码中只有微不足道的差异。
注意:我无法更改模式,因为实际模式是符合标准的医疗保健(HL7)模式。
