RE: [xsl] concatenate multiple attribute values and assign it to another

based on michael kay response or abels response if I do, the problem is
I get 4 outputs of testnode
i.e
<testnode att1="1,2,3,4" att2="a,b,c,d" />
<testnode att1="1,2,3,4" att2="a,b,c,d" />
<testnode att1="1,2,3,4" att2="a,b,c,d" />
<testnode att1="1,2,3,4" att2="a,b,c,d" />

I want it to output only once.
This is what I have done based on michaels response. The following is a
portion of the xslt file I have.

 <xsl:template match="//testnode">
    <testnode>
      <xsl:attribute name="att1">
        <xsl:for-each select="//testnode">
          <xsl:value-of select="@att1"/>
          <xsl:if test="position()!=last()">,</xsl:if>
        </xsl:for-each>
      </xsl:attribute>
      <xsl:attribute name="att2">
        <xsl:for-each select="//testnode">
          <xsl:value-of select="@att2"/>
          <xsl:if test="position()!=last()">,</xsl:if>
        </xsl:for-each>
      </xsl:attribute>
    </testnode>
  </xsl:template>

In XSLT 2.0 (correcting your XML input)

<testnode>
  <xsl:attribute name="att1" select="testnode/@att1" separator=","/>
  <xsl:attribute name="att2" select="testnode/@att2" separator=","/>
</testnode>

In 1.0

<testnode>
  <xsl:attribute name="att1">
    <xsl:for-each select="testnode">
      <xsl:value-of select="@att1"/>
      <xsl:if test="position()!=last()">,</xsl:if>
etc.
