Default Generating a comma-delimited data in XSLT

I have some data in xml that looks like this:

<AllServices>
  <Service ID="1">a</Service>
  <Service ID="2">b</Service>
  <Service ID="3" />
  <Service ID="4">d</Service>
</AllServices>

The Service element values are dynamic and each element doesn't contain its value all the time. I'm trying to display the data as comma delimited via XSLT, so this is what I have:

<xsl:for-each select="AllServices/Service">
  <xsl:if test=".!=''">
    <xsl:value-of select="." />
    <xsl:if test="position()!=last()">, </xsl:if>
  </xsl:if>
</xsl:for-each>

This only works when the last Service element contains a value. If the last Service element does not contain a value, it leaves the comma at the end of the list like this: a, b,

I need to get rid of the last comma even when the last element value is not present. Can someone tell me how I can achieve this? Thanks in advance!

Change the <xsl:for-each> to select="AllServices/Service[.!='']"

and then get rid of the first <xsl:if> test.

Change

<xsl:for-each select="AllServices/Service">
  <xsl:if test=".!=''">
    <xsl:value-of select="." />
    <xsl:if test="position()!=last()">, </xsl:if>
  </xsl:if>
</xsl:for-each>

to

<xsl:for-each select="AllServices/Service[.!='']">
    <xsl:value-of select="." />
    <xsl:if test="position()!=last()">, </xsl:if>
</xsl:for-each>

Or in XSLT 2.0 it becomes a one-liner:

<xsl:value-of select="AllServices/Service[.!='']" separator=", "/>
