| Running DOMFilter |

`DOMFilter` parses an XML document, searching for specific elements by name, or elements with specific attributes.

Requirements:

- Xerces-J is loaded on your computer.
- JDK is loaded on your computer.

Source code:

- DOMFilter.java

| DOMFilter |

To run DOMFilter:

1. open up a MS-DOS command line window
2. set the path to the jdk\bin directory
3. change directory to the latest xerces-1_4_4 directory
4. invoke the `DOMFilter` sample

On Windows:

The easiest way to do this is to create a .bat file using the Notepad editor. Then the `DOMFilter` can be invoked by double clicking on the file name or icon. The following command lines assume that both the jdk and the xerces-1_4_4 directories are located directly below the c: dirve.

    set PATH=%PATH%;c:\jdk1.1.8\bin
    set CLASSPATH=%CLASSPATH%;c:\xerces-1_4_4\xerces.jar;c:\xerces-1_4_4\xercesSamples.jar
    cd c:\xerces-1_4_4
    java dom.DOMFilter data/personal.xml

Switches:

`DOMFilter` also allows you to change the default behavior using the following command line flags (type this in as one long command line):

- -p Specify the parser class to be used.
  The available parsers are:

- dom.wrappers.DOMParser [default parser]

- -h Print DOMCount help information. [default is no help]
- -e Specify the name of the element to search for. [defaults to matching all elements]
- -a Specify the name of the attribute to search for. [defaults to matching all attributes]

Running `DOMFilter` with the default settings is equivalent to running `DOMFilter` like this:

    java dom.DOMFilter -p dom.wrappers.DOMParser
        data/personal.xml

Bringing up the help information:

    java dom.DOMFilter -h

Searching for elements:

    java dom.DOMFilter -e family data/personal.xml

Search for attributes:

    java dom.DOMFilter -a subordinates data/personal.xml

| Parse your own XML file instead of data/personal.xml
