[jdom-interest] return specific XML node within a for-loop

[Phil Weighill Smith]

I personally would use an XPath expression (JDOM has an XPath mechanism
but you will need to include additional JARs on your classpath). To get
the description for a given coffeeName element you can do something
like:

public String getCoffeeDesc(Document doc, String coffeeName) {
    XPath xpath = XPath.newInstance("//row[./coffeeName/text() = " +
coffeeName + "]/coffeeDesc/text()");
    Text coffeeDesc = (Text)xpath.selectSingleNode(doc);
    return coffeeText.value();
}

Hope that helps.
