The XML datatype supports writing XML to Strings, output streams or writers.

Writing to a String:

  1. import static org.camunda.spin.Spin.XML;
  2. import org.camunda.spin.xml.SpinXmlElement;
  4. // Create XML element
  5. SpinXmlElement element = XML("<root id=\"test\"/>");
  7. String xml = element.toString();
  9. String value = element.attr("id").value();

Writing to an Output Stream:

  1. import static org.camunda.spin.Spin.XML;
  2. import org.camunda.spin.xml.SpinXmlElement;
  3. import org.camunda.spin.xml.SpinXmlAttribute;
  5. // Create XML element
  6. SpinXmlElement element = XML("<root id=\"test\"/>");
  8. try {
  10.   // Define Output Stream
  11.   OutputStream outputStream = System.out;
  13.   // Wrap Output Stream in Writer
  14.   OutputStreamWriter outputStreamWriter = new OutputStreamWriter(outputStream);
  16.   // Write element to stream writer
  17.   element.writeToWriter(outputStreamWriter);
  19.   // Get attribute from element
  20.   SpinXmlAttribute attr = element.attr("id");
  22.   // Write attribute value to stream writer
  23.   attr.writeToWriter(outputStreamWriter);
  25.   // End Output Stream
  26.   outputStreamWriter.write("\n");
  28.   // Close Output Stream and Writer
  29.   outputStreamWriter.close();
  31. } catch (IOException e) {
  32.   // Handle exception if needed
  33. }

Write to Writer

  1. import static org.camunda.spin.Spin.XML;
  2. import org.camunda.spin.xml.SpinXmlElement;
  3. import org.camunda.spin.xml.SpinXmlAttribute;
  5. // Create XML element
  6. SpinXmlElement element = XML("<root id=\"test\"/>");
  8. // Create String Writer
  9. StringWriter writer = new StringWriter();
  11. // Write element to Writer
  12. element.writeToWriter(writer);
  14. // Get attribute from element
  15. SpinXmlAttribute attr = element.attr("id");
  17. // Write attribute value to Writer
  18. attr.writeToWriter(writer);
