Join child values via XPath?

Question

I know my problem will be easily resolved if I have non-unique child nodes (by 'concat').

Problem:

<CarPlant>
      <Model>Audi</Model>
      <Model>Scoda</Model>
</CarPlant>

I would like to get a string e.g. "Audi,Scoda" to process it by scala's means.

Answer 1

This XPath 2.0 expression,

/CarPlant/string-join(Model,',')

will evaluate to

Audi,Scoda

for your XML, as requested.
