jOOX answers many Stack Overflow questions


jOOX - a jQuery port to Java When you search for Stack Overflow questions regarding XML, DOM, XPath, JAXB, etc, you could very often answer them simply with an example involving jOOX. Take this question extract for example:

Goal

My goal is to achieve following from this ex xml file :

<root>
    <elemA>one</elemA>
    <elemA attribute1='first' attribute2='second'>two</elemA>
    <elemB>three</elemB>
    <elemA>four</elemA>
    <elemC>
        <elemB>five</elemB>
    </elemC>
</root>

to produce the following :

//root[1]/elemA[1]='one'
//root[1]/elemA[2]='two'
//root[1]/elemA[2][@attribute1='first']
//root[1]/elemA[2][@attribute2='second']
//root[1]/elemB[1]='three'
//root[1]/elemA[3]='four'
//root[1]/elemC[1]/elemB[1]='five'

jOOX answer

The above can be achieved quite simply with jOOX (compared to the other answers to the question involving XSLT, SAX, DOM, etc):

List<String> list = $(document).xpath("//*[not(*)]").map(new Mapper<String>() {
  public String map(Context context) {
    return $(context).xpath() + "='" + $(context).text() + "'";
  }
}});

This will produce

/root[1]/elemA[1]='one'
/root[1]/elemA[2]='two'
/root[1]/elemB[1]='three'
/root[1]/elemA[3]='four'
/root[1]/elemC[1]/elemB[1]='five'

It is an “almost” solution to the OP’s problem, jOOX does not (yet) support matching/mapping attributes. Hence, attributes will not produce any output. This will be implemented in the near future, though.
