Instead of testing for city inside the for-each, why not only select the
Person elements you want? I.e. first

<xsl:for-each select="Person[City]">
  <xsl:value-of select="concat(Name, ' - ', City)"/>
</>

And then

<xsl:text>People not connected to city:</xsl:text>
<xsl:for-each select="Person[not(City)]">
  <xsl:value-of select="concat(Name, ' - ', City)"/>
</>

Cheers,
