Special characters XSD and XSLs
This module was developed in order to provide a standard way
of handling XChars markup.
So far, it was only possible by using the proprietary
XChars Java package
With a XML schema and some XSL stylesheets it should be
possible to access XChars information from virtually any
programming language, given that there is plenty of tools
for any of them related to these XML technologies.
Initially, this module's files come from processing
the XChars configuration file from maven artifact
This file was used as source for the XSLT stylesheets in
transforms the original specialCharacters.xml into an
equivalent XML schema (in src/main/resources
transforms the original specialCharacters.xml into
several XSL stylesheets - depending on the 'encoding'
parameter passed for the transformation -, in
src/main/resources directory. The resulting stylesheets
were manually simplified (for example, removing all the
<xsl:if/> generated for every chemical element,
all of them with the same formatting). Besides,
xchars2default.xsl had to be manually modified in order
to fix the 'composite' encoding used for some xchars
As only 'default', 'sp_code' and 'chebi_code' encodings
are currently in use, the others haven't been properly
maintained This results in lots of errors for their
resulting xsl stylesheets, which have been excluded
from the tests and the final maven artifact.
Use the XSD and XSL files as per your favourite tool documentation.
With the XSD schema you will be able to generate code or validate
XML containing xchars markup.
With the XSLs you can transform any text containing xchars markup
in your preferred encoding.
Please note that you will probably have to put the xchars text
into a XML element.
