XSLT transforms library

A nice collection of useful XSLT transforms, models and reusable fragments under GPL, involving HTML tables, XML Schema, HTML GUI, MathML, SQL analogy, etc. This has been developped as part of the "Worlwide Botanical Knowledge Base" project, ( http://wwbota.free.fr/ ).

The transforms fall within the following (mutually exclusive) categories :

proof of concept: aims at showing the possibilities of XSLT in various domains; far from production quality
pedagogical: small examples
design pattern: starting points of frequent use to write transforms, not for direct use but after editing (about design patterns see the book "Design Patterns" by E. Gamma et al.)
production: XSLT transforms of production quality, for direct use
template library: for use as imported stylesheet, of production quality

I strongly recommend Michael Kay's book (the author of the Saxon processor), whose sources can be downloaded from wrox.com .

Vision

Create a series of useful transforms, either acting on the structure of the document, or performing generic transforms (e.g. creating an index of words), or acting on well-knows documents (e.g. XML Schema, SVG, XHTML, ...), or merging or splitting in various ways. These transforms should be able to be re-assembled (by chaining-piping, import, or other combinations) to perform complex tasks out of simple bricks. This is coherent with the vision of an XML-centered application (see Extensible browsers and XML-compliant applications on this site). This way we could also do something as useful and flexible as the Unix shells commands (wc, sed, grep, ...), and C++ Standard Template library. This is a sub-project under GNU Public Licence, so contributions are wellcome!

An application of XSLT transforms library is XMLPublish, a Web document publication framework through XML. As an example, XMLPublish was used with this HTML page as the source for generation .

XML source	XSLT	Description	Category	Domain	Output
FinancialReport_1.htm	HTMLtable2XML.xslt	from HTML table to XML; generates XML tags from first row <th> tags UPDATED	production	XHTML	FinancialReport_1.xml
test.xml	queryOnSubElement.xslt	selects a given tag according to the content of a subelement	pedagogical	query	queryOnSubElement.xml

test.xml	identquery2.xslt	identity transform 2 : a good starting point to write XSLT transforms	design pattern
emptyElements.xml	suppressEmptyElements.xslt	suppress empty elements (i.e. elements with no text content)	production	structure	emptySuppressed.xml
testHREF.xml	selectHREF.xslt	extract href attributes; example of text mode output	pedagogical	XHTML	selectHREF.txt
testHREF.xml	attributes2elements.xslt	replace attributes with elements; reuses identity transform 2	production	structure	attributes2elements.xml
document-to-split.xml	split.xslt	split named first-level elements into files (XSLT 1.1) NEW	pedagogical	file structure	one file per first-level element
	append.xslt	merge after last first-level element of document at URL $main all first-level elements of input document .	production	file structure
	wrapper.xslt	wrap a nodeset fragment of XML inside an XML document. An attribute marker is used to tell where to insert the fragment.	library	file structure
	difference-by-value.xslt	difference by string value of first-level elements of trees in $v1 and $v2. Outputs a list of nodes in $v1 not having same string value as one of $v2 .	library	string, set
test-make-words-list.xslt: auto-sufficient stylesheet	make-words-list.xslt	from a whitespace-separated string, outputs an sorted list of unique words occuring in $string .	library	string

To transform:

With Saxon (http://users.iclway.co.uk/mhkay/saxon/):

java -classpath /home/jars/saxon.jar com.icl.saxon.StyleSheet $*

With XT

xt Data XSLT

xt Data XSLT result

xt is a command-line (or Java) XSLT processor available from www.jclark.com .
