SimpleXML: Value and Attribute on same Node

155 views Asked by RigaJona At 10 January 2022 at 10:08

Is it possible, to address a nodes Attributes and Value with SimpleXML? For example in tag "from":

<?xml version="1.0" encoding="UTF-8"?>
  <note>
    <to>Tove</to>
    <from name="test">Jani</from> 
    <heading>Reminder</heading>
    <body>Dont forget me this weekend!</body>
  </note>

I couldn't find a way to address the content of the node in my code. My example code for this XML would be:

public class Note 
{
    @Element(name = "to")
    private String to;

    @Element(name = "from")
    private Sender from;

    @Element(name = "heading")
    private String heading;

    @Element(name = "body")
    private String body;
    
}

public class Sender 
{

    private String content;

    @Attribute(name = "name")
    private String attribute;

}

Now im looking for a annotation for Sender.content which addresses the value note/from/Jani

According to the official documentation, you can use the annotation @Text:

Example below:

Adding text and attributes to elements

As can be seen from the previous example annotating a primitive such as a String with the Element annotation will result in text been added to a names XML element. However it is also possible to add text to an element that contains attributes. An example of such a class schema is shown below.

@Root
public class Entry {

   @Attribute
   private String name;

   @Attribute
   private int version;     

   @Text
   private String value;

   public int getVersion() {
      return version;           
   }

   public String getName() {
      return name;
   }

   public String getValue() {
      return value;              
   }
}

Here the class is annotated in such a way that an element contains two attributes named version and name. It also contains a text annotation which specifies text to add to the generated element. Below is an example XML document that can be generated using the specified class schema.

<entry version='1' name='name'>
   Some example text within an element
</entry>

The rules that govern the use of the Text annotation are that there can only be one per schema class. Also, this annotation cannot be used with the Element annotation. Only the Attribute annotation can be used with it as this annotation does not add any content within the owning element.

Your code will then look like:

public class Sender 
{

    @Text
    private String content;

    @Attribute(name = "name")
    private String attribute;

}
