Created a set of examples that demonstrate the new callback functionality of BSF4ooRexx 4.0
by using the Java SAX classes.

Run and look up the Rexx code and study the comments.

Usage:

        xyz.rxj www.rexxla.org.xhtml

        where "xyz.rxj" is one of:
                01_getText.rxj
                02_getText.rxj
                03_listElementNames.rxj
                04_listElementNamesIndented.rxj
                05_listElementNamesIndentedWithAttributes.rxj
                06_listElementNamesIndentedWithAttributes_DOES_NOT_USE_DTD.rxj
                07_listElementNamesAsTree.rxj


File list:
        01_getText.rxj
        02_getText.rxj
        03_listElementNames.rxj
        04_listElementNamesIndented.rxj
        05_listElementNamesIndentedWithAttributes.rxj
        06_listElementNamesIndentedWithAttributes_DOES_NOT_USE_DTD.rxj
        07_listElemen
        DTD/
        www.rexxla.org.xhtml

Note 1) the directory DTD is necessary as SAX will look it up for the DTD definition and
        additional support files

Note 2) "06_listElementNamesIndentedWithAttributes_DOES_NOT_USE_DTD.rxj" can be used with
        any XML-file or URL referring to a XML file; this is possible, because it ignores
        external DTD-files, hence the following would be possible with this script:

                06_listElementNamesIndentedWithAttributes_DOES_NOT_USE_DTD.rxj http://www.wu.ac.at
                06_listElementNamesIndentedWithAttributes_DOES_NOT_USE_DTD.rxj http://www.rexxla.org
                ...
