The most straightforward solution is:

<p><xsl:value-of select="firstname"/><xsl:text> </xsl:text><xsl:value-of 
select="lastname"/></p>

This is necessary because whitespace in stylesheets is normally 
discarded unless it's next to non-whitespace text. Wrapping the literal 
whitespace in <xsl:text> tells the processor "I really want this to be 
output exactly as it appears here."

There are other ways to do it, of course -- anything that generates a 
whitespace value will accomplish the task -- but this is the one that 
will make the stylesheet easiest for a human to read.

FWIW, we've seen a number of cases where the tutorials at w3schools have 
been ... well, let's be charitable and say "incomplete". They may have 
improved since then, but you might want to consider looking at other 
sources as well or instead. My standard recommendation is the 
DeveloperWorks XML site, http://www.ibm.com/xml, but I admit to being 
biased.
