XSLT

• xslstylesheet
• A stylesheet is represented by an xslstylesheet
  element in an XML document.
• xsltransform is allowed as a synonym for
  xslstylesheet.
• The namespace http//www.w3.org/1999/XSL/Transform
  is used to recognize the XSL elements

4

• A template rule is specified with the
  xsltemplate element.
• The content of the xsltemplate element is the
  template
• The match attribute is a Pattern that identifies
  the source node or nodes to which the rule
  applies.

5

• select
• A select attribute can be used to process nodes
  selected by an expression.
• The value of the select attribute is an
  expression.
• The xslvalue-of element is instantiated to
  create a text node in the result tree.

6

• xsltext
• ltxsltext ...gt ... lt/...gt
• as raw text but allows control of white-space
  stripping and escaping
• ltxslcommentgt ... lt/...gt
• creates comment

7

• The xslfor-each instruction contains a template,
  which is instantiated for each node selected by
  the expression specified by the select attribute.
  The select attribute is required
• ltxslfor-each select"node-set expression"gt
  template lt/...gt
• instantiate template for each node in node-set
• ltxslapply-templates select"node-set expression"
  .../gt
• apply pattern matching and template instantiation
  on selected nodes (default all children)

• Sorting is specified by adding xslsort elements
  as children of xslapply-templates or
  xslfor-each. The first xslsort child specifies
  the primary sort key, the second xslsort child
  specifies the secondary sort key and so on.
• When used in xslfor-each, xslsort elements must
  occur first.

30

• order specifies whether the strings should be
  sorted in ascending or descending order
  ascending specifies ascending order descending
  specifies descending order the default is
  ascending
