Showing multiple nested tags 1

[silverfang]

When I am working with an xsl stylesheet and I want to display something like:
<1>
<2>
<3>
<4></4>
<4></4>
<4></4>
<4></4>
</3>
</2>
<2>
<3>
<4></4>
<4></4>
</3>
</2>
</1>

... with <xsl:value-of select="1/2/3/4"/> it only displays the first <4>-tag of each <3>-element. How can I display them al if I have a random number of <4>-tags

There's 2 main ways of doing it. You can use a for-each:

<xsl:for-each select="1/2/3/4">
  <xsl:value-of select="."/>
</xsl:for-each>

Or, my preferred option, you can use templates. Templates give more meaning to the code and make it more readable:

<xsl:template match="/">
  <xsl:apply-templates select="1/2/3/4"/>
</xsl:template>
<xsl:template match="4">
  <xsl:value-of select="."/>
</xsl:template>

I would stick to templates where possible, but sometimes it makes more sense to use for-each.
