If you can't persuade someone to change this appalling data structure, try:

<xsl:for-each select="Address">
    <xsl:value-of select="Address"/>
    <xsl:variable name="p" select="position()"/>
    <xsl:value-of select=../City[$p]"/>
</xsl:for-each>

Don't even think of incrementing variables in XSLT: it's not a sequential,
procedural language.
