<s1 title="&XercesCName; Sample 1: SAXCount">

    <s2 title="SAXCount">
        <p>SAXCount is the simplest application that counts the elements and characters of
        a given XML file using the (event based) SAX API.</p>

        <s3 title="Building on Windows">
	        <p>Load the &XercesCInstallDir;-win32\samples\Projects\Win32\VC6\samples.dsw
	        Microsoft Visual C++ workspace inside your MSVC IDE. Then
	        build the project marked SAXCount.</p>
        </s3>

        <s3 title="Building on UNIX">
<source>cd &XercesCInstallDir;-linux/samples
./runConfigure -p&lt;platform&gt; -c&lt;C_compiler&gt; -x&lt;C++_compiler&gt;
cd SAXCount
gmake</source>
	        <p>This will create the object files in the current directory
			and the executable named
	        SAXCount in '&XercesCInstallDir;-linux/bin' directory.</p>

	        <p>To delete all the generated object files and executables, type</p>
<source>gmake clean</source>
        </s3>

        <s3 title="Running SAXCount">

          <p>The SAXCount sample parses an XML file and prints out a count of the number of
          elements in the file. To run SAXCount, enter the following </p>
          <source>SAXCount &lt;XML File&gt;</source>
          <p>The following parameters may be set from the command line </p>
<source>Usage:
    SAXCount [options] &lt;XML file>

Options:
    -v=xxx      Validation scheme [always | never | auto*]
    -n          Enable namespace processing. Defaults to off.

This program prints the number of elements, attributes,
white spaces and other non-white space characters in the input file.

  * = Default if not provided explicitly</source>
          <p><em>-v=always</em> will force validation<br/>
             <em>-v=never</em> will not use any validation<br/>
             <em>-v=auto</em> will validate if a DOCTYPE declaration is present in the XML document</p>
          <p>Here is a sample output from SAXCount</p>
<source>cd &XercesCInstallDir;-linux/samples/data
SAXCount -v=always personal.xml
personal.xml: 60 ms (37 elems, 12 attrs, 134 spaces, 134 chars)</source>
          <p>Running SAXCount with the validating parser gives a different result because
          ignorable white-space is counted separately from regular characters.</p>
<source>SAXCount -v=never personal.xml
personal.xml: 10 ms (37 elems, 12 attrs, 0 spaces, 268 chars)</source>
          <p>Note that the sum of spaces and chracters in both versions is the same.</p>

          <note>The time reported by the program may be different depending on your
          machine processor.</note>
