Groovy String Concatenation

Question

Current code:

row.column.each(){column ->
    println column.attributes()['name']
    println column.value()
}

Column is a Node that has a single attribute and a single value. I am parsing an xml to input create insert statements into access. Is there a Groovy way to create the following structured statement:

Insert INTO tablename (col1, col2, col3) VALUES (1,2,3)

I am currently storing the attribute and value to separate arrays then popping them into the correct order.

Answer 1

I think it can be a lot easier in groovy than the currently accepted answer. The collect and join methods are built for this kind of thing. Join automatically takes care of concatenation and also does not put the trailing comma on the string

def names = row.column.collect { it.attributes()['name'] }.join(",")
def values = row.column.collect { it.values() }.join(",")
def result = "INSERT INTO tablename($names) VALUES($values)"
