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

[Kiran R. <tec...@gm...>]

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:

@Root
public 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.
