9. XSLT (XSL Transformations).
- Lecture notes
- Further reading
- Practical work: Xalan and Emacs on venus
-
On Windows, start XSession and login to venus via Putty
(make sure "Enable X11 forwarding" is ticked in Putty
configuration).
-
Copy the shell script
clt232-xalan to your directory.
Make it executable (chmod +x clt232-xalan).
This script runs the open source
Xalan Java XSLT transformer.
-
On venus, use GNU Emacs (via XSession) to edit XML
files and XSLT stylesheets. Use the Xalan script
(via Putty) to do XSLT transformations.
Check the HTML output files in a web browser and in a text editor.
- "Hello, World": Copy
hello.xml,
hello.xsl
to your directory.
Transform the XML file to HTML with the stylesheet by
./clt232-xalan -in hello.xml -xsl hello.xsl -out
hello.html
- Empty stylesheet: Copy
empty.xsl
to your directory.
Transform the XML file to HTML with the empty stylesheet by
./clt232-xalan -in hello.xml -xsl empty.xsl -out
empty.html
-
XSLT Tutorial
(only "XSLT Basic"): Copy
cdcatalog.xml and stylesheets
cdex1.xsl,
cdex2.xsl,
cdfor.xsl,
cdfilter.xsl,
cdsort.xsl,
cdif.xsl,
cdchoose.xsl.
Transform cdcatalog.xml with all the stylesheets like this
(example 1):
./clt232-xalan -in cdcatalog.xml -xsl cdex1.xsl -out
cdcatalog.html
10. XPath and XSLT. Transforming XML to XHTML.
- Lecture notes
-
XPath
from XML in a Nutshell by Harold & Means (O'Reilly)
- Further reading
- Practical work: XSLT and XPath in jEdit
-
On Windows, use jEdit to edit XML files and
XSLT stylesheets. Use jEdit's XSLT plugin to run
Xalan Java
inside jEdit to do XSLT transformations.
-
On Windows, start jEdit and open
Plugins -> Plugin Manager -> Install tab.
In the Install tab, tick XSLT then click
the Install button to install it.
-
The XSLT plugin includes XPath Tool and XSLT Processor.
Use jEdit's menus to open them. Use the docking options to
dock XPath Tool on the right and to dock XSLT Processor on
the bottom.
-
Copy the files
hello.xml,
hello.xsl,
empty.xsl
again, this time to your temporary Windows folder.
Open hello.xml in jEdit and use jEdit's XSLT plugin
to do the XSLT transformations again (inside jEdit)
using the two stylesheets.
-
Copy
cdcatalog.xml and the example stylesheets
again, this time to your temporary Windows folder.
Open cdcatalog.xml in jEdit and use the XSLT plugin
to do the XSLT transformations again inside jEdit.
-
In jEdit we can use the XPath plugin to check which parts
of an XML document are selected by different XPath
expressions. We can do this without actually doing any
XSLT transformations.
-
Copy the
XPath
examples
9-1.xml,
9-2.xsl,
9-3.xsl,
9-4.xsl
to your temporary Windows folder.
In jEdit, use the XPath plugin to check which parts of
9-1.xml
are selected by the various XPath expressions included in
the stylesheets.
-
Then use the XSLT plugin to do the transformations, and
check the results.
- Practical work: Xalan and Emacs on venus (continued)
-
Copy the
XPath
examples
9-1.xml,
9-2.xsl,
9-3.xsl,
9-4.xsl
to your directory.
Do the transformations with the example stylesheets, for example:
./clt232-xalan -in 9-1.xml -xsl 9-2.xsl -out 9-2.html
-
Copy
sonnet130.xml,
sonnet.dtd,
sonnet-html.xsl
to your directory.
Validate the sonnet against the DTD (same as last week) by
./clt232-xerces -v sonnet130.xml
-
Transform the sonnet from XML to HTML with the stylesheet by
./clt232-xalan -in sonnet130.xml -xsl sonnet-html.xsl
-out sonnet130.html
-
Copy another of
Shakespeare's sonnets
(or compose your own sonnet).
Edit it to create the same XML format, validate it with
the same DTD,
and transform it to HTML with
the same XSLT stylesheet.
