Examples of nu.xom.ProcessingInstruction

nu.xom.ProcessingInstruction
This class represents an XML processing instruction. Each processing instruction has two key properties:
- The target, a non-colonized name
- The data, a string which does not contain the two character sequence ?>. The syntax of the data depends completely on the processing instruction. Other than forbidding ?>, XML defines no rules for processing instruction data.
