# Scanner Item

An `Scanner` item can appear inside a Module Item, and allows to define artifacts dependency, according to the artifacts contents. For example scanner for "qrc" files:

    import qbs.Xml

    Module {
      Scanner {
        condition: true
        inputs: 'qrc'
        scan: {
          xml = XmlDomDocument(input.fileName);
          dependencies = [];
          // do something with the xml
          return dependencies;
        }
      }
    }
