  • The content inside the &lt;xsl:template&gt; element defines some HTML to write to the output.
  • &lt;xsl:template match="/"&gt; &lt;html&gt;
  • &lt;xsl:stylesheet&gt;, defines that this document is an XSLT style sheet document
  • ...3 more annotations...
  • &lt;xsl:template&gt; element is used to build templates. The match attribute is used to associate a template with an XML element. The match attribute can also be used to define a template for the entire XML document. The value of the match attribute is an XPath expression (i.e. match="/" defines the whole document).
  • Since an XSL style sheet is an XML document itself, it always begins with the XML declaration: &lt;?xml version="1.0" encoding="ISO-8859-1"?&gt;
  • An XSL style sheet consists of one or more set of rules that are called templates. Each template contains rules to apply when a specified node is matched.

  • How Does it Work? In the transformation process, XSLT uses XPath to define parts of the source document that should match one or more predefined templates. When a match is found, XSLT will transform the matching part of the source document into the result document.
  • XSLT Uses XPath XSLT uses XPath to find information in an XML document. XPath is used to navigate through elements and attributes in XML documents.
  • A common way to describe the transformation process is to say that XSLT transforms an XML source-tree into an XML result-tree.
  • ...2 more annotations...
  • XSLT is used to transform an XML document into another XML document, or another type of document that is recognized by a browser, like HTML and XHTML. Normally XSLT does this by transforming each XML element into an (X)HTML element.
  • What is XSLT? XSLT stands for XSL Transformations XSLT is the most important part of XSL XSLT transforms an XML document into another XML document XSLT uses XPath to navigate in XML documents XSLT is a W3C Recommendation

  • In the absence of a select attribute, the xsl:apply-templates instruction processes all of the children of the current node, including text nodes
  • &lt;xsl:template &nbsp;&nbsp;match = pattern &nbsp;&nbsp;name = qname &nbsp;&nbsp;priority = number &nbsp;&nbsp;mode = qname&gt;
  • &lt;xsl:call-template &nbsp;&nbsp;name = qname&gt;
  • ...2 more annotations...
  • Templates can be invoked by name.
  • An xsl:call-template element invokes a template by name; it has a required name attribute that identifies the template to be invoked
