Re: [Simple-support] Interpret a sub-element as String

[Niall G. <gal...@ya...>]

Did you try 

   @Path("sub-element")
    @Element(name="name")
    public String subElement;

or

   @Path("sub-element")
    @Element
    public String name;

 Tried the
 @Path annotation as well. The problem I found there is that
 ultimately, I need to also annotate the field that has the
 Path annotation with another annotation that states whether
 it is an element, attribute or Text.
 Since my aim is to extract the value
 as a String, I tried the @Text annotation:
 @Rootpublic class
 RootElement {    @Element   
 public String description;
    
 @Path("sub-element")   
 @Text    public String
 subElement;
    
 public RootElement() {   
 }}
 I also
 tried @Element. However none of this works. I get a
 ValueRequiredException for subElement. I can of course add a
 required=false, but that does not serve my
 purpose.
 It looks like
 I'm missing some fundamental point about how Path
 expressions are supposed to work!
 Also, the docs for Path state that a
 subset of XPath expressions are supported and goes on to
 list a few examples. Is this an exhaustive list of supported
 expressions?
 I tried
 something like @Path("sub-element/text()") and it
 threw a PathException.

 Hi,
 
 
  
 
 
 Here's an XML I
 have:
 
 
  
 
 
 <root-element>
 
 
    
 <description>lorem-ipsum</description>
 
 
     <sub-element
 id="1"><name>Hello
 World</name></sub-element>
 
 
 </root-element>
 
 
  
 
 
 Now, for whatever reason,
 I want to read the <sub-element> part as a String
 rather than as an object - i.e.,
 
 
  
 
 
 @Root(name="root-element",
 strict=false)
 
 
 class RootElement
 {
 
 
    
 @Element(name="description")
 
 
     String
 description
 
 
     
 
 
     //No @Element
 annotation here.
 
 
     String
 subElement;
 
 
 }
 
 
  
 
 
  
 
 
 RootElement root = new
 Persister().read(RootElement.class,
 INPUT);
 
 
  
 
 
 RootElement EXPECTED = new
 RootElement("lorem-ipsum", "<sub-element
 id=\"1\"><name>Hello
 World</name></sub-element>");
 
 
 assertEquals(EXPECTED,
 root);
 
 
  
 
 
 Similarly, when I
 serialize this RootElement object, I want the string to
 appear as a sub-element.
 
 
  
 
 
  
 
 
 Any idea on how to go
 about doing this? It looks like I am looking for some sort
 of interceptor - I get the partially parsed object and then
 I can fill in the missing fields. 
 
 
  
 
 
 I tried using a Converter
 and the @Convert annotation; I tried implementing a Visitor
 - in both cases I got stuck trying to figure out what
 portion has been parsed already.
 
 
  
 
 
 I have temporarily written
 code to first parse the object with all fields except
 subElement; and then set this field using sub-string
 operations. However, this is not really scalable -
 especially when I use sub-element inside a list, inside
  other parent elements, or when root-element itself has
 other parent elements etc.
