Yes, it's entirely possible, but you still haven't given a very precise
specification. For example if there are two identical elements under "add"
do you require exactly two matching elements under "delete"? Or at least
two? Or is one enough?

You could start with something like

<xsl:for-each select="add/*">
  <xsl:if test="../../delete/*[name()=current()/name()]">
    ... there's a match ...
  </xsl:if>
</xsl:for-each>
