However, a text node in XPath cannot contain elements, so that apply-templates will never do anything. The second template matches *, which is short for "any element", so it explicitly does not match text nodes, and elements _can_ contain other elements of course. The reason there was no change is presumably because the default template for text nodes looke a bit like <xsl:template match="text()"> <xsl:value-of select="." /> </xsl:template> which, after you ignore the useless call to apply-templates, is the same as what you have there. And the template with * is probably not being called, unless there were elements in your document that no other template matched.
