did you mean

  table1: query4, query2

as query1 is not a direct parent of table1.

Hopefully this will get you started.

  <xsl:key name="x" match="Table | Query" use="@name"/>
  <xsl:output method="text"/>
  <xsl:template match="Queries">
    <xsl:for-each select="descendant::*[generate-id(.) = generate-id(key('x', @name))]">
      <xsl:if test="key('x', @name)[parent::Query]">
        <xsl:value-of select="@name"/>: <xsl:text/>
        <xsl:for-each select="key('x', @name)">
          <xsl:if test="not(position() = 1)">, </xsl:if>
          <xsl:value-of select="../@name"/>
        </xsl:for-each>
        <xsl:text>&#xA;</xsl:text>
      </xsl:if>
    </xsl:for-each>
  </xsl:template>
