Examples of org.apache.uima.util.XMLInputSource

org.apache.uima.util.XMLInputSource
An input source used by the {@link XMLParser} to read XML documents for parsing.
The application uses the {@link #XMLInputSource(File)} constructor to create anXMLInputSource from a descriptor File. Alternatively, if the source of the XML is not a file, the {@link #XMLInputSource(InputStream,File)} constructor may beused to read the XML from an input stream. The second argument to this constructor is the relative path base, to be used if the descriptor contains imports with relative paths. It is acceptable to set this to null if it is known that the descriptor does not contain any such imports.
