XPath and XSLT (II) - Sady

To continue XPath:

Selecting Nodes (VBScript)
set xmlDoc=CreateObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.load("books.xml")

xmlDoc.selectNodes(path expression)

For example: xmlDoc.selectNodes("/bookstore/book[0]/text()")

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. XSLT uses XPath to find information in an XML document.

How to transform XML into XHTML using XSLT

Start with a Raw XML Document

<?xml version="1.0" encoding="ISO-8859-1"?>

<?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?>

<cd>

<title>Empire Burlesque</title>

<artist>Bob Dylan</artist>

<company>Columbia</company>

</cd>

</catalog>

Create an XSL Style Sheet (such as cdcatalog.xsl)

<?xml version="1.0" encoding="ISO-8859-1"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">

<html>

<body>

<h2>My CD Collection</h2>

<xsl:apply-templates/>

<th align="left">Title</th><th align="left">Artist</th>

</tr>

<xsl:for-each select="catalog/cd[artist!='Bob Dylan']">

<xsl:sort select="artist"/>

<xsl:if test="price > 10">

<tr>

<xsl:choose>

<xsl:when test="price > 10">

</xsl:when>

<xsl:otherwise>

</xsl:otherwise>

</xsl:choose>

</tr>

</xsl:if>

</xsl:for-each>

</table>

</body>

</html>

</xsl:template>

</xsl:stylesheet>

Transforming XML to XHTML in the Browser

// Load XML

var xml = new ActiveXObject("Microsoft.XMLDOM")

xml.async = false

xml.load("cdcatalog.xml")

// Load XSL

var xsl = new ActiveXObject("Microsoft.XMLDOM")

xsl.async = false

xsl.load("cdcatalog.xsl")

// Transform

document.write(xml.transformNode(xsl))

</script>

Transforming XML to XHTML on the Server (ASP)

'Load XML

set xml = Server.CreateObject("Microsoft.XMLDOM")

xml.async = false

xml.load(Server.MapPath("cdcatalog.xml"))

'Load XSL

set xsl = Server.CreateObject("Microsoft.XMLDOM")

xsl.async = false

xsl.load(Server.MapPath("cdcatalog.xsl"))

'Transform file

Response.Write(xml.transformNode(xsl))

Open, Edit and Save XML...
