XSTL syntax summary

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)
