I believe the following facts are true:
- alpha's value is a node set
- each alpha/beta's value is a single text node
- xsl:value-of returns the value of a single node, not the value of a node
set.
I.e. it selects and returns the value of the first node matching the XPath
query.
Therefore:
- <xsl:value-of select="alpha"> returns the value of the single <alpha>
node; which is a node set containing 3 nodes.
- <xsl:value-of select="alpha/beta"> returns the value of the first <beta>
node under the <alpha> node; which is a text node.
To get what you want, you need to do the following:
<xsl:for-each select="alpha/beta">
<xsl:value-of select="."/>
</xsl:for-each>
