Transforming Data to XML
We can get the data from the database and create different representations using Groovy builders. Here is an example that creates an XML representation (see Building XML) of the data in the weather table:
| WorkingWithDatabases/Weather.groovy | |
| | bldr = new groovy.xml.MarkupBuilder() |
| | |
| | bldr.weather { |
| | sql.eachRow('SELECT * from weather') { |
| | city(name: it.city, temperature: it.temperature) |
| | } |
| | } |
The code produces this XML output:
| WorkingWithDatabases/Weather.output | |
| | <weather> |
| | <city name='Austin' temperature='48' /> |
| | <city name='Baton Rouge' temperature='57' /> |
| | <city name='Jackson' temperature='50' /> |
| | <city name='Montgomery' temperature='53' /> |
| | <city name='Phoenix' temperature='67' /> |
| | <city name='Sacramento' ... |
