Converting xml to csv using groovy

Question

I am trying to convert the below XML to CSV using groovy XmlSlurper().parseText() , but nothing is printed when moving to inner node.

Xml File :

 string input = """<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<executeQueryInSpaceResponse>
    <executeQueryInSpaceResult>

Groovy Code :

content = new XmlSlurper().parseText(input)
println content
println content.executeQueryInSpaceResponse.executeQueryInSpaceResult

It is not printing anything. The expected output will be like,

Expected Output CSV File:

The header of the csv file should be :

Name,First Name,Last Name,Address Line 1,Address Line 2,City,State,Country,Postal Code,Program,Campus Name,Date ASP,Date LEGACY,Success 1,Success 2,Received Date,Submitted Date,Complete Date,Decision Date,Registration Date,FDOC Date,Status,Step,LeadId,Source,Vendor,Client,SAVEDEXPRESSION

And the Rows should be,

ABCDEF,ABC,DEF,Shilo,,August,Georgia,,34566,Studies,August,,,Clerk,,2016-01-05 00:00:00.000,,,,,,Not Qualified,Unintended Request,512544989,marketing,Interactive,,0

Answer 1

The line you put inside the code will return you the root node of the xml.

content = new XmlSlurper().parseText(input)

If you put content.executeQueryInSpaceResponse will return nothing. because the content is your root node executeQueryInSpaceResponse . Both are same.

you need to replace the code as shown below :

println content.executeQueryInSpaceResult

and also I suggest you to refer Groovy-XML Parsing . Enjoy Coding !

Answer 2

Here is a snippet to help you:

def header = content.executeQueryInSpaceResult.columnNames.children().collect().join(',')
def csv = content.executeQueryInSpaceResult.rows.children().inject(header){ result, row ->
 [result, row.children().collect().join(',')].join("\n")
}
