background: LightCyan; 6/8 XSL Transformation continents.xml + continents.xsl → continents.html ● Some ways to run the transformation for the next tasks ● Netbeans: right click on the xml file → XSL transformation... ● Java: using javax.xml.transform.* classes ● xsltproc - xsltproc continents.xsl continents.xml > continents.html ● Online converters, like: – https://xslttest.appspot.com – https://www.freeformatter.com/xsl-transformer.html 7/8 Task 01 (week03) ● Download the project seminars/xslt2-zadani.zip and uncompress locally in a directory ● The goal of the task is to complete file transf.xsl so that the transformations run on data.xml give as output the file data.html (that you can use as example of the expected result) Using the command line (or the implementation in the project or methods mentioned in the previous slide): xsltproc transf.xsl data.xml > out.html (out.html can then be compared with data.html) ● Upload the final XSL file to homework vault sem07/task01-week03/ 8/8 References Suggested material: ● XSLT Specifications →https://www.w3.org/TR/xslt ● W3C School XSLT pages: →https://www.w3schools.com/xml/xsl_intro.asp ● XSLT Tutorial → http://zvon.org/comp/r/tut-XSLT_1.html ● XSLT Elements → https://www.w3schools.com/xml/xsl_elementref.asp ● Online XSLT Quick Card →https://www.cheatography.com/univer/cheat-sheets/xslt-2-0-cheat-sheet/pdf/
