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.

NoteThe time reported by the program may be different depending on your machine processor.
