Recursive processing

Recursive processing instructions:

<xsl:apply-templates select="node-set expression" .../>
apply pattern matching and template instantiation on selected nodes (default: all children)
<xsl:call-template name="..."/>
invoke template by name (where xsl:template has name="..." attribute)
<xsl:for-each select="node-set expression"> template </...>
instantiate inlined template for each node in node-set (document order by default)
<xsl:copy> template </...>
copy current node to output and apply template (shallow copy)
<xsl:copy-of select="..."/>
copy selected nodes to output (deep copy, includes descendants)

The select attribute contains an XPath expression, which is evaluated in the current context.

Example:

<xsl:template match="article"> <h1><xsl:apply-templates select="title"/></h1> </xsl:template>

Processing modes: mode="..." on xsl:template and xsl:apply-templates allows an element to be processed multiple times in different ways.
