## Detailed Description

The QXmlLocator class provides the XML handler classes with information about the parsing position within a file.

The reader reports a QXmlLocator to the content handler before it starts to parse the document. This is done with the QXmlContentHandler::setDocumentLocator() function. The handler classes can now use this locator to get the position (lineNumber() and columnNumber()) that the reader has reached.
