Working examples are provided with the dpkq package. Here are some of this example files (all the example files can be seen at at http://hg.savannah.gnu.org/hgweb/epeios/file/tip/tools/dpkq/Test). You will see some tags/attributes prefixed with xpp: in some files. This is because this files goes through the Epeios XML preprocessor.
There are also project files (i. e. files with .xprj extension) you can give as argument to dpkq. Records stored in the Elements.xml (more precisely in its element_.xml sub-file) data file refers directly or indirectly to records of the other data files.
The Viewer entry in the project files (defined in the common.xprj file) should actually launch a Web browser to display the output XML file after applying the XSL file on it. As there is no cross-platform standard way to do this, the Viewer tag contains a command which displays the content of the available markers. Modify this entry at your convenience, but remember that some Web browser does not perform the XSL transformation, apparently due to some security issues. In this case, you can call a script which applies explicitly the XSL transformation, and then opens the Web browser with the resulting HTML file…
As a musician, I use dpkq to work my scores. For this, I created following tables :
In the examples, for simplification purpose, the Voices table and Segments table are not present. Also, the final result show only some formatted line of text per record, instead of showing a scan of page(s) of the score corresponding to the measures of segment as in my use of dpkq.
