XSLT stands for Extensible Stylesheet Language Transformations and enables transforming XML documents into other formats like HTML. XSLT uses XML documents called stylesheets that contain elements and attributes to define templates that match elements in the XML data and specify how to transform their contents. Transformations can occur on a server, client, or with a standalone program and involve elements like <template> to select nodes, <apply-templates> to process children, <value-of> to retrieve node values, <for-each> to loop through nodes, and <sort> to sort output.

1. XSLT

2. Introduction
• Stands for Extensible Styles Language
Transformations
• enables to transform XML documents into
another form
• For example, we can take XML document,
combine it with HTML/CSS, and it will look
completely different when viewing it in your
user agent/browser

3. XSLT Documents
• Is a valid XML document
• Consists of a number of
elements/tags/attributes
• These can be XSL elements or elements from
another language (such as HTML)

4. Processing a Transformation
• A transformation can take place in one of
three locations:
– On the server
– On the client (for example, your web browser)
– With a standalone program

5. XSLT Syntax
• XML Version
• XSL Root Element
• XSL Namespace Prefix

6. XML Version
• XSL documents are also XML documents and
so we should include the XML version
• We should also set the standalone attribute to
no
<?xml version="1.0" standalone="no"?>

7. XSL Root Element
• Root element needs to include the XSL version
as well as the XSL namespace

8. XSL Namespace Prefix
• All XSL elements in XSLT document must include
the XSL prefix
• Syntax:
<xsl:element_name>
• Example:
<xsl:template match="/">
....
</xsl:template>

9. XSLT <template> Element
• The <xsl:template> element is what we use to
select a node from XML document and
transform its contents
• To select an element, we use the match
attribute.
• To transform its contents, we simply place the
new content between the opening
(<xsl:template>) and closing (</xsl:template>)
tags

12. Example

15. XSLT <apply-templates> Element
• <xsl:template> element allows us to select any
node in our XML document and transform its
contents
• We can also use this element to work with the
children of that node.
• <xsl:apply-templates/> element allows us to
determine where the content of its children
appear on our transformed document

16. Example

18. XSLT <value-of> Element
• <xsl:value-of> element allows to retrieve the
value from a node
• When using the <xsl:value-of> element, we
use the select attribute to specify which node
we want to retrieve data from

19. Example

21. XSLT <for-each> Element
• <xsl:for-each> element allows to loop through
multiple nodes that match the selection
criteria
• This in turn, enables to retrieve data from
these nodes
• <xsl:for-each> is used in conjunction with
<xsl:value-of>

22. Example

25. XSLT <sort> Element
• <xsl:sort> element allows to sort the output of
the <xsl:for-each> element
