Xquery: returning multiple data elements using Java?

Question

I have the following xml:

<Products>
    <Product>
        <name>Sample name</name>
        <attribute id="sampleid" location="sampleLocation" type="sampleType"/>
        <price>12345</price> 
    </product>
</Products>

How can I return the following data from this XML for a given name (always unique):

1. location (e.g. "sampleLocation")
2. type (e.g. "sampleType")
3. price (e.g. 12345

I currently am able to query each individually to return values, but im not sure of the syntax to return multiple values together.

Example of individual query for location:

 ResourceSet resourceSet = service.query(
                        format("//Products/Product[name='%s']" +
                                        "/attribute/@Location/string()"
                                , StringEscapeUtils.escapeXml(journey_Name)
                        ));

The query above will return: "sampleLocation".

What XQuery processor and what API are you using?

The following query returns a sequence of three strings:

/Products/Product/(string(attribute/@location), string(attribute/@type), string(price))

How to return a sequence of three strings to your Java app depends on the XQuery processor and API that you are using, which you haven't told us.
