XSLT <xsl:template> Element - 0 views

www.w3schools.com/...xsl_templates.asp

shared by David Gelpi Fleta on 26 Nov 07 - Cached
  • 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.
  • &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).
  • &lt;xsl:template match="/"&gt; &lt;html&gt;
  • ...3 more annotations...
  • 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;
  • &lt;xsl:stylesheet&gt;, defines that this document is an XSLT style sheet document
  • The content inside the &lt;xsl:template&gt; element defines some HTML to write to the output.

  • 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
  • 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.
  • 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 Uses XPath XSLT uses XPath to find information in an XML document. XPath is used to navigate through elements and attributes in XML documents.
  • 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.

shared by David Gelpi Fleta on 26 Nov 07 - Cached
  • The &lt;xsl:for-each&gt; Element The XSL &lt;xsl:for-each&gt; element can be used to select every XML element of a specified node-set:
  • &lt;xsl:for-each select="catalog/cd"&gt;
  • We can also filter the output from the XML file by adding a criterion to the select attribute in the &lt;xsl:for-each&gt; element.
