Based on: http://www.w3schools.com/xsl/xsl_templates.asp.
<xsl:template match="/">matches whole document<xsl:value-of>extract value from a node, e.g.<xsl:value-of select="catalog/cd/title"/>, but it will get only first occurence!- <xsl:for-each> allows loops:
<xsl:for-each select="catalog/cd">
...
<xsl:value-of select="title"/>
...
</xsl:for-each> - filtering out the data from previous example:<xsl:for-each select="catalog/cd[artist='Bob Dylan']">
(artist is at the same level as title) - sorting - put <xsl:sort select="artist"/> element inside for-each element
- selecting - embrace the content with <xsl:if test="price > 10"> element inside for-each element
- selecting multiple things (taki switch):
<xsl:choose>
<xsl:when test="price > 10">
...
</xsl:when>
<xsl:otherwise>
...
</xsl:otherwise>
</xsl:choose> - <xsl:apply-templates> element - applies a template to the current element or to the current element's child nodes (xsl:apply-templates select="title"/> - apply the XSLT to the children named title.. if we define several "xsl:apply-templates", at the same time we specify the order in which the children will be processed)
