XSLT

XSLT is a full-fledged programming language, written in declarative, rather than imperative form. Most computer programming languages are written in an imperative form, instructing the computer what to do in a clearly defined sequence of steps. XSLT takes a different approach! It is declarative, which means that you declare what you want to happen but allow your computer processor to evaluate how to accomplish that.

“XSLT” stands for eXtensible Stylesheet Transformation Language, and it has a heritage in publisher technologies.

How to organize the oXygen XML Editor to write XSLT

Two ways

XSLT Transformation Scenario
- Start from your XML file
- Click the icon ‘configure transformation scenario’
- New > XML transformation with XSLT
- Assign a name to the scenario
- In the tab ‘XSLT’ select the XSLT file that you want to use for the transformation
- Change to the tab ‘Output’ and save your file as e.g. ‘something.html’
- Select the checkbox ‘open in browser’ and ‘open in editor’
- Click ‘ok’ and ‘apply’
- If you want to reuse your saved transformation scenario, you only need to click on the button ‘apply transformation scenario’ (red arrow)

How to prepare oXygen XML Editor to write XSLT over TEI

Setting the @xpath-default-namespace
Another way of doing it (using the tei: namespace prefix on element nodes
Setting the output namespace

Template rules

Default template processing (in the absence of explicit template rules)
“Push” processing (process most everything, and you don’t have to have template rules
“Pull” processing using the @select attribute

Processing methods

xsl:apply-templates
xsl:value-of (vs. type-aware xsl:sequence)
xsl:for-each
