Validating Xml

To validate the Map xml file, reference mapnik's mapfile DTD as in:

    <?xml version="1.0" encoding="utf-8"?>
    <!DOCTYPE Map SYSTEM "mapnik2.dtd">
    <Map>
    ...
    </Map>

The DTD file can be found here: https://github.com/mapnik/mapnik/blob/master/utils/xml/mapnik.dtd

Validating in editors

• Eclipse
• One time validation: right click on the xml file -> validate
• Automatic validation: right click on project -> properties -> Validation -> Add Validation Builder to project -> OK

Validating from the command line

    xmllint --valid --noout path/to/file.xml
