I got this XML structure:
<Tax>
<Money currency="USD">0.00</Money>
<Description xml:lang="en">
17.5% Non-Recoverable
<ShortName>vatspecial</ShortName>
</Description>
</Tax>
Notice that Description
node has MixedContent
(composed with text and XML) and this is the XSD
part regarding Description
node:
<xsd:complexType name="TaxDescriptionType">
<xsd:sequence>
<xsd:element name="ShortName" type="xsd:string" />
</xsd:sequence>
<xsd:attribute ref="xml:lang" />
</xsd:complexType>
Everything is ok at this point, XJC
outputs the generated classes like this one regarding TaxDescriptionType
:
package org.com.project;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;

import javax.xml.bind.annotation.XmlType;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "TaxDescriptionType", propOrder = {
"shortName"
})
public class TaxDescriptionType {
@XmlElement(name = "ShortName", required = true)
protected String shortName;
@XmlAttribute(name = "lang", namespace = "http://www.w3.org/XML/1998/namespace")
@XmlJavaTypeAdapter(CollapsedStringAdapter.class)
@XmlSchemaType(name = "NCName")
protected String lang;
/**

public String getShortName() {

}
/**

public void setShortName(String value) {
this.shortName = value;
}

public String getLang() {

public void setLang(String value) {

}
}
Then, with the above class
I am able to work around with the elements like this:
taxDescriptionType.setLang("en");
taxDescriptionType.setShortName("vatspecial");
/* missing value: 17.5% Non-Recoverable */
But the problem is that I can't found a way to get
or set
the 17.5% Non-Recoverable
text of the MixedContent-ComplexType
from the above XML
example.
This is what I tried and it's not working:
mixed="true"
attribute like this: <xsd:complexType name="TaxDescriptionType" mixed="true">
(I think XJC is ignoring the last attribute)
Doing some research, I found this:
JAXB XJC compiler disregarding mixed=true on XML Schema documents
But I am not sure if this is the way to solve this. One of the answers said that this is a bug and in the other one shows a code that transforms the MixedContent
into a List<Serializable>
and maybe the next situation will be about how to deal with this:
taxDescriptionType.getContent().add(Serializable element);
(And I really don't know how to deal with a Serializable
element)
As you mentioned you need to add the mixed
attribute to indicate that your type supports mixed content. Without this specified your XML content is invalid:
<xsd:complexType name="TaxDescriptionType" mixed="true">
<xsd:sequence>
<xsd:element name="ShortName" type="xsd:string" />
</xsd:sequence>
<xsd:attribute ref="xml:lang" />
</xsd:complexType>
The generated TaxDescriptionType
class will have the following property. Essentially this means that all of the non-attribute content will be stored in a List
. This is necessary because you need a mechanism that indicates where the text nodes are wrt the element content.
@XmlElementRef(name = "ShortName", namespace = "http://www.example.org/schema", type = JAXBElement.class)
@XmlMixed
protected List<Serializable> content;
You will populate this list with instances of String
(representing text nodes) and JAXBElement
(representing element content).
ALTERNATIVELY
Mixed content generally makes life more complicated than it needs to be. If possible I would recommend an alternate XML representation.
<Tax>
<Money currency="USD">0.00</Money>
<Description xml:lang="en" ShortName="vatspecial">
17.5% Non-Recoverable
</Description>
</Tax>
Or
<Tax>
<Money currency="USD">0.00</Money>
<Description xml:lang="en">
<LongName>17.5% Non-Recoverable</LongName>
<ShortName>vatspecial</ShortName>
</Description>
</Tax>
