+ \example xml/xmlstreamlint
+ \title XML Stream Lint Example
+
+ The XML Stream Lint example provides a simple command line utility that
+ accepts a file name as its single argument and writes it to the standard
+ output file.
+
+ The specified file is parsed using an QXmlStreamReader object and written
+ to the standard output file using an QXmlStreamWriter object. If the file
+ does not contain a well-formed XML document or the use of namespaces in
+ the document is incorrect, a description of the error is printed to
+ the standard error file and will appear in the console.
+
+ \section1 Basic Operation
+
+ The main function of the example opens the file specified by the user
+ for input (\c inputFile), and it uses QFile to access the standard output
+ file.
+
+ Reading XML is handled by an instance of the QXmlStreamReader class, which
+ operates on the input file object; writing is handled by an instance of
+ QXmlStreamWriter operating on the output file object:
+
+ \snippet examples/xml/xmlstreamlint/main.cpp 0
+
+ The work of parsing and rewriting the XML is done in a while loop, and is
+ driven by input from the reader:
+
+ \snippet examples/xml/xmlstreamlint/main.cpp 1
+
+ If more input is available, the next token from the input file is read
+ and parsed. If an error occurred, information is written to the standard
+ error file via a stream, and the example exits by returning a non-zero
+ value from the main function.
+
+ \snippet examples/xml/xmlstreamlint/main.cpp 2
+
+ For valid input, the writer is fed the current token from the reader,
+ and this is written to the output file that was specified when it was
+ constructed.
+
+ When there is no more input, the loop terminates, and the example can
+ exit successfully.
