Lab 3. Output two pieces of data from the Wordpress streaming web site

Copy the XSLT code from Example06 into this folder. It outputs the <title>
within <entry>. You are to output both the source <title> and the author <name>.

However, there is a problem. One of the streaming rules is that you cannot make
two downward selects. So you cannot select both title and name. However, you can
make a copy of the <entry> element like so:

    <xsl:variable name="entry" select="copy-of(.)" />
    
Now you can output the title and name within $entry. That is, $entry is not
restricted by any streamability rules.
