使用JAXB将子节点中的XML数据作为字符串获取 [英] Getting a XML data present in a child node as string using JAXB
问题描述
我正在使用JAXB将XML（Parent XML，FIXML）转换为String。在该XML中，一个子节点具有另一个XML（子XML，FpML）数据，我已经为其创建了模式（xsd）。在Parent XML的模式中，具有Child XML的元素类型被定义为String。我需要孩子XML应该作为字符串。请让我知道我必须做些什么改变。我对JAXB比较陌生。在此先感谢.. !!
I am using JAXB to convert the XML(Parent XML, FIXML) to String. In that XML one child node is having another XML(Child XML, FpML) data for which I done have schema (xsd). In the schema for the Parent XML, the element type which has the Child XML is defined as String. I need the child XML should come as the string. Please let me know what change I have to do. I am relatively new to JAXB. Thanks in Advance..!!

根据您的评论：
嗨..感谢您的回复.. @Blaise
Doughan&在你提供的上面
示例中的@CoolBeans你提到
字符串值但是在我的
xml中，而不是字符串值，
将是其中的另一个XML。比如
Richard
我需要输出
Richard作为
字符串。请告诉我
仍然需要更多信息。
谢谢..干杯，Sakthi。 S
Hi.. Thanks for your reply.. @Blaise Doughan & @CoolBeans in the above example you provide you have mentioned String Value but in my xml, instead of "String Value" there will be another XML inside it. like Richard and I need the "Richard" as string in the output. Please let me know still you want more information. Thanks.. Cheers, Sakthi. S
您可以使用@XmlAnyElement和DomHandler实现的组合来处理此用例。有关详细示例，请参阅：
You can use a combination of @XmlAnyElement and a DomHandler implementation to handle this use case. For a detailed example see:

更新＃2
根据您的评论
您能告诉我什么是更改
需要在架构中完成make
提交@XmlAnyElement，因为我
在
构建时生成java类。
Can you please tell me what is change need to be done in the schema to make that filed "@XmlAnyElement", since I am generating the java classes on the build time.
您可以使用JAXB dom 架构注释来在属性上生成XmlAnyElement：
You can use the JAXB dom schema annotation to cause an XmlAnyElement to be generated on a property:
XJC致电
xjc -d out -b bindings.xml dom.xsd
dom.xsd
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.example.com/default"
targetNamespace="http://www.example.com/default">
<xs:element name="customer">
<xs:complexType>
<xs:sequence>
<xs:element ref="address"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="address">
<xs:complexType>
<xs:attribute name="street" type="xs:string"/>
</xs:complexType>
</xs:element>
</xs:schema>

<jxb:bindings schemaLocation="string.xsd">
<jxb:bindings node="//xs:element[@name='customer']/xs:complexType/xs:sequence/xs:element[@ref='address']">
<jxb:dom/>
</jxb:bindings>
</jxb:bindings>
</jxb:bindings>
客户
Customer 上的地址属性将使用 @XmlAnyElement 进行注释：
The address property on Customer will be annotated with @XmlAnyElement:
package com.example._default;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAnyElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
import org.w3c.dom.Element;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"address"
})
@XmlRootElement(name = "customer")
public class Customer {
@XmlAnyElement
protected Element address;
public Element getAddress() {
return address;
}
public void setAddress(Element value) {
this.address = value;
}
}
原始答案
您可能正在寻找@XmlValue注释。例如，如果您有以下类：
You may be looking for the @XmlValue annotation. For example if you had the following class:
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD
public class Child {
@XmlValue
private String value;
}
以上课程将编组为：
<child>String Value</child>
在相应的XML模式中，子元素的类型为xs：string。
In the corresponding XML schema the type of the child element would be xs:string.
<xs:element name="child" type="xs:string"/>
