Sample: DOMCount

DOMCount

DOMCount uses the provided DOM API to parse an XML file, constructs the DOM tree and walks through the tree counting the elements (using just one API call).

Running DOMCount

The DOMCount sample parses an XML file and prints out a count of the number of elements in the file. To run DOMCount, enter the following

    DOMCount <XML file>

The following parameters may be set from the command line

    Usage:
        DOMCount [options] <XML file | List file>

    This program invokes the DOM parser, builds the DOM tree,
    and then prints the number of elements found in each XML file.

    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*].
        -n          Enable namespace processing. Defaults to off.
        -s          Enable schema processing. Defaults to off.
        -f          Enable full schema constraint checking. Defaults to off.
        -?          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 DOMCount

    cd &XercesCInstallDir;-linux/samples/data
    DOMCount -v=always personal.xml
    personal.xml: 20 ms (37 elems)
