Sample: SAX2Count

| SAX2Count |
| SAX2Count is the simplest application that counts the elements and characters of a given XML file using the (event based) SAX2 API.
| Running SAX2Count |
| The SAX2Count sample parses an XML file and prints out a count of the number of elements in the file. To run SAX2Count, enter the following
    SAX2Count <XML File>
The following parameters may be set from the command line
    Usage:
        SAX2Count [options] <XML file | List file>

    This program invokes the SAX2XMLReader, and then prints the
    number of elements, attributes, spaces and characters found
    in each XML file, using SAX2 API.

    Options:
        -l          Indicate the input file is a List File that has a list of xml files.
                    Default to off (Input file is an XML file).
        -v=xxx      Validation scheme [always | never | auto*].
        -f          Enable full schema constraint checking processing. Defaults to off.
        -n          Disable namespace processing. Defaults to on.
                    NOTE: THIS IS OPPOSITE FROM OTHER SAMPLES.
        -s          Disable schema processing. Defaults to on.
                    NOTE: THIS IS OPPOSITE FROM OTHER SAMPLES.
        -locale=ll_CC specify the locale, default: en_US
        -?          Show this help.

      * = Default if not provided explicitly.
-v=always will force validation -v=never will not use any validation -v=auto will validate if a DOCTYPE declaration or a schema declaration is present in the XML document Here is a sample output from SAX2Count
    cd xerces-c_2_8_0-linux/samples/data
    SAX2Count -v=always personal.xml
    personal.xml: 60 ms (37 elems, 12 attrs, 134 spaces, 134 chars)
Running SAX2Count with the validating parser gives a different result because ignorable white-space is counted separately from regular characters.
    SAX2Count -v=never personal.xml
    personal.xml: 10 ms (37 elems, 12 attrs, 0 spaces, 268 chars)
Note that the sum of spaces and characters in both versions is the same.
| The time reported by the program may be different depending on your machine processor.
