Using the Schema Framework, I often have to write non-trivial XSL code. From parsing values to selecting from a set of options, XSL code can be difficult to write due to the restrictions of the language.

There are some techniques I have found or developed that have been very useful. Unfortunately, I forget the details of the more unusual solutions when I need them again. This project will be the reference of my solutions.

The examples should be in paired files, and XML and XSL file with the same name that should be used together.

For the most part, the output will be text, though you should be able to view the results by opening the XML file with a browser. My preferred method to check the results is to use xsltproc:

 $ xsltproc parse_vals.xsl parse_vals.xml

Note the main two parameters of xsltproc are the XML file and the XSL file. Remember to put the XSL file first on the command line.

The focus of this idea is the XSL file, dup_doc.xsl. The companion file, dup_doc.xml is a simple document with a variety of XML items to test and confirm how they are, or are not, duplicated.
