value-of misses children 2003-02-27 - By Gary L Peskin
Have a look at how xsl:value-of works. Your select attributes evaluate to
node-sets. The xsl:value-of element then converts those node-sets to
strings as if by call to the string function. The string function converts
a node-set to a string by returning the string-value of the node in the
node-set that is first in document order.
For your first xsl:value-of, the select evaluates to a node-set containing a
single Element node, <alpha>. The string-value of this node is the
concatenation of all the string values of all text node descendants of
<alpha> which is what you see.
For your second xsl:value-of, the select evaluates to a node set containing
two Element nodes, <beta>. The string-value of this node-set is the
concatenation of all the string values of all the text node descendants of
the -first- <beta> element, which is what you see.
Perhaps you want xsl:copy-of?
