• XSL/XSLT are XML based languages.

• XSL / XSLT allows us to convert one XML structured document into another (data formatting)

• XSLT is the most common part and it is supported in most web browsers

What is XSL(T)

XSLT is a pattern matching language(rather than a procedural language) that uses templates to generate an output

XSLT Basics

• XSLT processes nodes of XML document.

  • Uses patten matching to identify the nodes.

  • Performs transformation on those nodes

  • Create a new documents

• Type of XSLT nodes

  • Document

  • Processing Instruction

  • ELement

  • Attribute

  • Text

  • Namespace

  • Comment

• XSLT templates

  • Describe the output based on the matched pattern.

  • Templates can be invoked:

Calling templates

• Can be called by name or by matching nodes against a pattern

• It's a declaration, so appears as a child node of the stylesheet element.

XSLT Functions

Template construct(What to do)

• xsl: value - of

  Note: if multiple values are returned, value-of only returns the first node value

• xsl: for - each

   <xsl:for-each select=“nodePattern”/>

• xsl: if

   <xsl:if test=“condition”>

• xsl: choose

   <xsl:choose> 
      <xsl:when test=“condition”> ?<xsl:when>
      <xsl:otherwise> </xsl:otherwise>
   </xsl:choose>

• xsl: apply - templates

XSLT Function

• ceiling() round decimal up to the nearest integer.

• floor() round decimal down to the nearest integer.

• count() determine the quantity in a set.
