Element occur more than once (unmarshall no namespace xml)

[cesarAugusto]

Hi everybody.

 

I´m trying to unmarshall an xml file with no namespace, I have the structure bellow in that file:

<a>

    <b>

        <c>

            <name index=1>NameOne</name>

            <name index=2>NameTwo</name>

            <name index=3>NameThree</name>

        </c>

    </b>

</a>

 

So I need to assign the second occur(NameTwo) of the tag name to a String property in my class "Dog", the property's name is "name".

 

My Class is something like this:

 

public class Dog{

  private String name;

  public Dog(){

   

  }

  public String getName(){

    return this.name;

  }

  public void setName(String name){

    this.name = name;

  }

} 

 

Finally my mapping.xml have the follow structure to unmarshall the xml file.

 

<class name="Dog">

  <map-to xml="a"/>

 

  <field name="name" type="java.lang.String">

    <bind-xml name="name" node="element" location="b/c"/>

  </field>

</class>

 

If I try to unmarshaller the xml file with that Structorure Castor throw me an exception tell me "Element "name" occur more than once".

 

The key point that is in the line ( <bind-xml name="name" node="element" location="b/c"/> ) How can I tell to castor that I need the second occur of name

(  <name index=2>NameTwo</name> )?

 

I can't change the xml to put a nameSpace, when I used DOM whith XPATH I would use a XPATH like this: "a/b/c/name[position()=2]". there is any way to do something like this with castor.

 

Thanks in advance.

Hi Cesar,

I am afraid that that won't be able with Castor - for several reasons,
that is.

a) Provided the mapping you are using, the XML does not match the
structure you have defined in your mapping. Your field mapping

<field name="name" type="java.lang.String">
  <bind-xml name="name" node="element" location="b/c"/>
</field>

indicates that the 'name' property of your Dog class does not allow
multi-valuedness. That's your first break.

b) You are slightly mis-interpreting the location attribute. This
attribute is designed to allow pre-pending XML artefacts that you do not
want to have in your Java POJOs. It is a structural element only, and
not designed to be used to identify specific occurrences of XML
artefacts at run-time.

Regards
Werner
