| <s1 title="Sample: SAX2Count"> |
| |
| <s2 title="SAX2Count"> |
| <p>SAX2Count is a simple application that counts the elements and characters of |
| a given XML file using the (event based) SAX2 API.</p> |
| |
| <s3 title="Running SAX2Count"> |
| |
| <p>The SAX2Count sample parses an XML file and prints out the number of |
| elements and characters in the file. To run SAX2Count, enter the following </p> |
| <source>SAX2Count <XML File></source> |
| <p>The following parameters may be set from the command line </p> |
| <source> |
| 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. |
| </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 or a schema declaration is present in the XML document</p> |
| <p>Here is a sample output from SAX2Count</p> |
| <source>cd &XercesC3InstallDir;/samples/data |
| SAX2Count -v=always personal.xml |
| personal.xml: 60 ms (37 elems, 12 attrs, 134 spaces, 134 chars)</source> |
| <p>Running SAX2Count with the validating parser gives a different result because |
| ignorable white-space is counted separately from regular characters.</p> |
| <source>SAX2Count -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 characters in both versions is the same.</p> |
| |
| <note>The time reported by the program may be different depending on your |
| processor speed.</note> |
