copied!<p>This is easy. The XSLT processor does all the recursion and the looping for you, all you need to do is to specify templates for nodes you want to handle.</p> <pre><code><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >  <xsl:template match="items[item]"> <ul> <xsl:apply-templates select="item" /> </ul> </xsl:template>  <xsl:template match="items[not(item)]" />  <xsl:template match="item[@name]"> <li> <xsl:value-of select ="@name" /> <xsl:apply-templates select="items" /> </li> </xsl:template>  <xsl:template match="item[not(@name)]"> <li> <xsl:value-of select ="id" /> <xsl:apply-templates select="items" /> </li> </xsl:template> </xsl:stylesheet> </code></pre> <p>The <code><xsl:apply-templates></code> always is the recursive/iterative step in XSLT. It takes any nodes that fit its <code>select</code> expression and finds templates for them.</p> <p>Your job is it to craft an appropriate <code>select</code> expression, supply a template for every node you want to handle and otherwise get out of the way. ;-) Resist the urge to cram everything into one big template or use <code><xsl:for-each></code> just because it feels convenient - it is not. Separate templates create more reusable and maintainable, less deeply nested code, and XSLT processors are optimized for template handling, so this might even be the more efficient approach.</p>
