2. What is XSL?
• XSL is a language that allows one to describe a browser
how to process an XML file.
• XSL can convert an XML file into another XML with
different format.
• XSL can convert an XML file into a non-XML file.

3. Purpose
• The most common type of XSL processing is to convert XML file
into HTML file which can be displayed by browsers. We will
focus on this use of XSL.
• XSL is the bridge between XML and HTML.
• We can use XSL to have different HTML formats for
the same data represented in XML.
• Separating data (contents) from style tags (display
commands).

14. XSl:copy
• Copying:
• xsl:copy, copies the current node
• xsl:apply-templates, processes the children of the current node
• ex. <xsl:stylesheetxmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
• <xsl:template match="title">
• <xsl:copy>
• <xsl:apply-templates/>
• </xsl:copy>
• </xsl:template>
• </xsl:stylesheet>
• xsl:copy-of element, can copy the entire subtree of each node that the
template selects
– ex. <xsl:template match="title“>
– <xsl:copy-of select="*"/>
– </xsl:template>
