[Simple-support] How do I use the value of an XML element when setting the path?

[Arthur E. <ar...@bl...>]

I've posted this question onto Stackoverflow, but thought I should post it
here to see if anyone has an answer:
http://stackoverflow.com/questions/12298673/how-do-i-use-the-value-of-an-xml-element-when-setting-the-path-in-the-java-simpl

I have the following XML:

<rdr>
  <details>
    <detail>

        <name>version</name>
        <value>15.0</value>

    </detail>
    <detail>
        <name>resolution</name>

        <value>1080X1920</value>
    </detail>

  </details>
</rdr>

and I am marshalling this into the following Java bean:

import org.simpleframework.xml.Element;
import org.simpleframework.xml.Path;
import org.simpleframework.xml.Root;

@Root(name = "rdr", strict = false)

public class XmlBean {

@Path("details/detail[1]")
@Element(name = "value")

private String version;

@Path("details/detail[2]")
@Element(name = "value")
private String resolution;

public String getVersion() {


    return version;
}

public void setVersion(String version) {


    this.version = version;
}

public String getResolution() {

    return resolution;
}

public void setResolution(String resolution) {


    this.resolution = resolution;
}

}

I am using simple XML, version 2.6.6.

However, what I would like to do, is use the name elements in the XPath.
For example, rather than using the Path "details/detail[1]" I would like to
use "details/detail[name=version]". This doesn't work and I get an
org.simpleframework.xml.core.PathException: Invalid index for path
exception returned. I have tried surrounding version with ' to no avail.
>From what I understand of XPath, this is the correct syntax:
http://www.w3schools.com/xpath/xpath_syntax.asp Can anyone confirm that
this looks correct?

I've looked into the source code for the simple xml library and it is
handling the XPath processing by itself without using a 3rd party library.
I can see why it doesn't work, because it is only accepting digits and will
throw that exception for any char that isn't a digit.

I'm tempted to fix the library, but suspect that I am doing something wrong
and that there may be another annotation that I should be using or some
other syntax.

Is there another annotation that I can use to achieve what I am trying to
do? Is it possible to do what I am trying to do using Simple?
